Replacing the battery
Place the multimeter on its face, loosen the two screws on the rear
and remove the lower part of the case, lifting it from the bottom. The
lower and the upper part of the case are xed together at the top on
the front by means of wedges.
Remove the battery from the battery compartment and carefully
disconnect battery connectors.
Snap the battery connectors to a new 9 V battery and insert the
battery into the battery compartment.
Replace the lower part of the case. Start at the top on the front and
take care that the wedges are properly engaged at this point.
Tighten the lower part with the two screws.
Please destroy the batteries in an environment friendly way.
18.2 Fuses
A blown fuse is signalled on the LCD display the instant a measured
quantity having a voltage of more than 4 V is applied to the corresponding
connection sockets.
Then, the digital display (9) shows " FUSE"
The 16 A fuse protects the 3 A and 10 A ranges, the 1.6 A protects all
other current measuring ranges. All other measuring ranges continue to
function.
When a fuse blows, rst eliminate the cause of the overload before using
the multimeter again !
Fuse replacement
Open the multimeter same as for battery replacement
Remove the blown fuse, e.g. with the aid of a probe, and replace it
with a new one.
Permissible types
for current measuring ranges up to 300 mA:
Fast blowing fuse type 1.6 A / 500 V;6.3 mm x 32 mm.
for the 3 A and 10 A current measuring ranges:
Type Dimensions
Normal fuse 16 A / 600 V~10 mm x 38 mm
Caution :
Absolutely verify that only the specied fuse is installed!
If a fuse of other cut-out capacity, other nominal current or other switching
capacity is used, a dangerous situation exists, and there is danger of
damaging protective diodes, resistors or other components.
The shorting of the fuse holder is not permissible.

1. Introduction:
Thank you very much for selecting this Multimeter.
This handheld multimeters are suitable for use in the elds of
general electronics and electrical engineering.
These multimeters are manufactured as per DIN 43751
2. Safety features and safety precautions
You have chosen a multimeter which provides you a very high degree of
safety. The analog-digital m ultimeters ZIEGLER Multi 12S ...16S are
manufactured and tested in compliance with the safety standard DIN
VDE0411 and IEC 1010-1/DIN EN61010-1/VDE0411-1. In case of
incorrect use or careless handling, the safety of both user and multimeter
is not assured
For proper use and safe handling, it is absolutely necessary to read and
understand the operating instructions before using the meter.
For your safety and for protection of the multimeter, the ZIEGLER
Multi
12S...16S multimeters are tted with an Automatic terminal Blocking
System (ABS). It is coupled with the function selector switch which
blocks the terminal sockets not necessary for measurement.
Please note the following safety precautions:
The multimeter must be operated only by persons who understand
the danger of shock hazards and are aware of the necessary safety
precautions. Shock hazards exist wherever voltages of more than
30V (TRMS) are present.
Do not work alone in shock hazardous environment while carrying
out measurement.
The maximum permissible voltage between any of the terminal
sockets (7) and ground is 1000V. But voltages of more than 500V
must be applied only to the unblocked sockets on the voltage
measuring ranges (function selector switch (6) set to a ’’V position’’)
Take into account that unexpected voltages can occur on device
under test (e.g. defective instrument). For example, capacitors may
be charged to a dangerously high voltage.
Verify that the test leads are in good condition, e.g.no cracked
insulation, no open circuits in the leads or connectors.
This multimeter must not be used for measurements on circuits with
corona discharge (high voltage).
Be particularly careful when measuring on HF circuits. Dangerous
composite voltages may exist there.
Measurements under moist environmental conditions are not
permitted.
All current measuring ranges, with the exception of the 16A range of
RISH Multi 13S, are protected with fuse. The maximum permissible
voltage of the measuring circuit (=nominal voltage of the fuse) is
500V ~ on the "mA" ranges, 600V ~ on the "A" ranges.
You must use the "multimeter" only in power systems, when the
current circuit is protected by a fuse or a circuit breaker of 20A, and
when the nominal voltage of the system does not exceed 500V.
For safe voltage measurements in power systems upto 1000V, we
recommend the KS30 measuring adapter, which is available as an
accessory. Its internal resistance limits the measuring current in the
case of overvoltage, in correct operation and safely suppresses
sparking from spark gap. Also refer to Section "8.1 Voltage
measurement on electrical systems up to 1000V with KS30
measuring adapter.

replace the battery or the fuse!
18.1. Battery
Prior to initial start-up, or after storage of multimeter, verify that the battery
of multimeter does not leak. Repeat this check in regular short intervals.
If the battery leaks, completely remove the battery electrolyte carefully
with a moist cloth and install a new battery before you operate multimeter
again.
When the symbol " " (17) appears on the LCD (1) replace the battery
as soon as possible. Measurement can be done, but a reduced measuring
accuracy must be taken into account.
The multimeter operates with a 9 V at cell battery according to IEC 6 F
22 or IEC 6 LR 61 or with a suitable NiCd storage battery.

Repair, replacement of parts:
When opening the meter, live parts may be exposed. Therefore, the
meter must be disconnected from the measuring circuit prior to opening
its case for repair or replacement of parts. If repair cannot be avoided
unless the meter is opened and live, this work must only be performed
by a qualied person who understands the danger involved.
Faults and abnormal stress:
When it is realised that the safe operation is no longer possible, take the
meter out of service and secure it against accidental use.
Safe operation may not be possible,
when the meter shows obvious signs of damage,
when the meter no longer functions correctly,
after prolonged storage under adverse conditions,
due to severe stress during transportation.

Automatic TURN-OFF
The meter turns off automatically, when the measured value remains
constant (var iations of the measured v alue < + 2digits) for about 10
minutes and when neither a pushbutton nor the function selector switch
is operated during that time. It remains ON, however, when a current
measuring range is selected and a measured value>30digits is displayed.
How to prevent automatic TURN-OFF
In order to prevent automatic "TURN OFF" select "CONTINUOUSLY
ON" mode. For this, press y ellow multi-function pushbutton (5) and the
"ON/OFF" pushbutton (2) together. The function "CONTINUOUSLY ON"
is shown on the LCD (1) by the symbol (8).
Turning the multimeter OFF
Press the "ON/OFF" pushbutton (2).
4. Function and range selection
The function selector switch (6) is coupled with the Automatic terminal
Blocking System (ABS) which allows access only to two correct sockets
for each function. Prior to switching to the "mA" or "A" functions or from
the "mA" or "A" functions, remove the test lead from the corresponding
socket. When the test leads are plugged-in, the terminal blocking systems
prevents accidental switching to nonpermissible functions.

divisions so that variations of the measured values around "zero"can be
observed exactly. When the measured value exceeds the range of
indication, the left triangle (16) is shown before the polarity of the analog
indicator switches over after approximately 0.7s. The over range indication
on the measuring range (>3099 digits, on the range >1999) is shown
by the right triangle (13).
6. ’’DATA’’hold facility
The DATA function allows to automatically hold the measured values.
This is particularly useful, for instance, when connecting the probes to
the measuring point requires full attention. When the measured value is
applied and the ’’condition’’ according to the table shown below is met,
the meter holds the measured value on the digital display and emits a
sound signal. The probes can now be removed from the measuring point
and the measured value on the digital display (9) can be read. When the
measured value falls below the limit specied in the table, the meter is
reactivated for a new storage.
The analog indication is not inuenced by the DATA hold, The actual
measured value can still be noted / read. Note that with a held digital
display, the location of the decimal point is also held. With autoranging
selected, the measuring range of the analog indicator is no longer known.

As long as the DATA hold function is active, manual range selection is
not possible. The DATA hold function is switched OFF, when,
The "DATA” pushb utton (3) is pressed for approx. 1s. This is
acknowledged by 2 sound signals.
The function selector switch (6) is operated or
The multimeter is turned OFF and ON again.
7. Minimum value and Maximum value ’’MIN/MAX" storage facility.
With the MIN/MAX function, you can hold the minimum and the maximum
measured value which was applied to the input of the multimeter after
activating MIN/MAX function. The most important application is the
determination of the minimum and the maximum value for long-term
monitoring of measured quantities. MIN/MAX does not inuence the
analog indication The actual measured value can still be noted/read.
Apply the measured quantity to the meter and select the measuring
range prior to activating the MIN/MAX function.
With the function activated, you can select the measuring ranges only
manually, if you switch to another range, the stored MIN/MAX values are
cleared.

8.1Voltage measurement on electrical systems up to
1000V with the KS30 measuring adapter.
On low-Voltage systems, transient overvoltages of several kilovolts can
occur due to switching functions or lightning discharges. Direct connection
of your multimeter to such systems for voltage measurement can be
dangerous.
For voltage measurements in power systems with nominal voltages upto
1000V, use the KS30 measuring adapter. It is an adapter for multimeter
which eliminates dangers caused by overvoltages and incorrect operation
of the multimeter. It provides the following protective functions..
Protection of the input circuit of voltage measuring range of
multimeters. The internal resistance of the KS30 limits the current in
the case of overvoltage.
Overload capacity : contin uously 1200 Vrms
Transient (rise 10 ms/fall 1000 ms) 6 kV max.
Safe suppression of sparking from spark plug after overvoltage.
Current limitation in the case of incorrect operation (e.g. applying a
voltage to a current input)
Voltages above 1000V can be measured with a high-voltage probe,
provided the necessary safety precautions are taken !
9. Current Measurement
First disconnect the power supply to the circuit being measured and/
or to the load, and discharge all capacitors within that circuit.
Select the DC current measuring ranges as described in section4.1
With the function selector switch (6), select A for currents >300mA,
and mA for currents<300 mA. When measuring current of unknown
magnitude, select the highest measuring rangerst.
Select the function corresponding to the measured quantity by briey
pressing the yellow multi-function pushbutton (5). Each time the
pushbutton is pressed, alternate switching takes place between DC
and AC on the
ZIEGLER
Multi 12S...15S or between DC and (DC + AC)
on the ZIEGLER Multi 16S. The change-over is acknowledged by a sound
signal. The symbols DC and AC (11) are displayed as per selected
function on the LCD.
When selecting a range with the function selector switch (6), the DC
function is always set by default. When pressing the yellow multi-
function pushbutton (5) for a long time, the multimeter always switches
back to DC and acknowledges this by two sound signals.
Connect the multimeter in series with the load, as shown. Ensure
that the connections are tight (without contact resistance).
Notes on Current measurement :
The multimeter must be used only in the power systems, where the
current circuit is protected by a fuse or a circuit breaker of 20 A, and
when the nominal voltage of the system does not exceed 500V.
Make the measuring circuit connections mechanically strong and
secure so that they do not accidentally open. The conductor cross
sections and connection points should be designed to avoid excessive
heating.
On the 300 mA and 10 A ranges (16 A range for ZIEGLER Multi 13S), an
intermittent sound signal warns you, when the measured value
exceeds the upper range limit.
The current measuring ranges upto 300 mA are protected to a short

circuit current of 25 A by a fuse 1.6 A/500 V in conjuction, with power
diodes. The cut-out capacity of the fuse is 20kA at a rated voltage of
500V~ and ohmic load.
The 3 A and 10 A current measuring ranges are protected by a 16A/
600V fuse. The cut-out capacity of the fuse is 100 kA at a normal
voltage of 600 V ~ and ohmic load.
Caution:
The measuring ranges 3A and 16 A of ZIEGLER Multi 13S are not protected
by a fuse!
A blown fuse is signalled on the LCD the instant a measured quantity
having a voltage of more than 4 V is applied to the corresponding
connection sockets. Then, the digital display (9) shows the word
" FUSE"
After a fuse has blown, eliminate the cause of the overload before
using the meter again !
Replacement of the fuses is described in section ’’ 18. Maintenance’’.
9.1AC current measurement with (clip-on) current transformer
9.1.1 T ransformer output mA/A
Caution:
If current transformers are operated with an open circuit on the secondary
side, e.g. due to defective or disconnected leads, a blown fuse in the
meter, or a wrong connection, dangerously high voltages can occur at
the connectors. Therefore, verify that the current circuit of the multimeter
and secondary winding of transformer connected to the multimeter
forman intact circuit. Connect the transformer to the sockets and mA
and/or A.
The maximum permissible operating voltage is the nominal voltage of
the current transformer. When reading the measured value, take into
account the transformer ratio and the additional error in indication.
Transf ormer output ZIEGLER Multi 12S
The ZIEGLER Multi 12S shows the switching position ’’ A’’ and the
corresponding sockets. Connect to this socket a (clip-on) current
transformer with a transmission ratio of 1000:1; then the measured values
are displayed directly in the ’’A’’ range.
9.1.2 T ransformer output V
Many transformers have voltage output (refered as mV/A)
The secondary output must therefore be connected to the connection
sockets and V.
10. Resistance measurement
Verify that the device under test is electrically dead. External voltages
would falsify the measured result!
Set the function selector switch (6) to " W".
Connect the device under test as shown.

14
12.Capacitance measurement (ZIEGLER Multi 15S and 16S)
Verify that the device under test is electrically dead. External voltages
would falsify the measured results!
Set the function selector switch (6) to "F"
Connect the (discharged !) device under test to the " "and ’’F’’
sockets via test lead.
Notes:
Connect polarised capacitors with the " " pole to the " " socket.
Resistors and semiconductor junctions in parallel with the capacitor falsify
the measured results!
Zero adjustment on the 30 nF measuring range
When measuring small capacitance values on the 30 nF range, the
internal resistance of the multimeter and the capacitance of the leads
can be eliminated by zero adjustment.
Connect the test leads to the meter without device under test.
Briey press the yellow multi-function pushbutton (5).
The meter acknowledges zero adjustment by a sound signal, by
displaying "00.00"" (+1digit) on the LCD and by a ashing decimal
point. The capacitance measured at the instant the pushbutton is
pressed is used as reference value (max.200digits). It is automatically
deduced from the values measured thereafter.
The zero adjustment can be cleared
By pressing the yellow multi-function pushbutton (5) for a long time,
clearance is acknowledged by the two sound signal.
By switching the multimeter off.
13. Frequency measurement ( ZIEGLER Multi 15S and 16S)
Frequency measurement is possible on all voltage measuring ranges in
AC,DC and (AC+DC) modes.
Set the function selector s witch 6) to V ~, V or V
Connections are made the same way as for voltage measurement,
See foot note (8) on page 21.
Briey press the yellow multi-function pushbutton (5)
The multimeter switches to frequency measurement. The frequency
is displayed on the LCD.
See section "17. Specications" for the lowest measurable
frequencies and the maximum permissible voltages.
Changing over between voltage, frequency and duty cycle
measurement
Repeated brief pressing of the yellow multi-function switch (5) changes
the measuring functions in the following order:
Voltage frequency duty cycle voltage ....
From frequency or duty cycle measurement, directly switching back
to voltage measurement is possible.
by pressing the yellow multi-function pushbutton (5) for a long time.
The meter acknowledges this by two sound signals. The voltage
measuring range last selected is maintained.
by operating the function selector switch (6).
15
14. Duty cycle measurement (ZIEGLER Multi 15S and 16S)
With duty cycle measurement, we can determine the ratio of pulse
duration to cycle time of recurring square-wave signals.
Set the function selector switch (6) to V or V
Connections are made in the same way as for voltage measurement
(See foot note 8) on page 21.
Briey press the yellow multi-function pushbutton (5) twice.
The meter switches to duty cycle measurement. The duty cycle-that
is the percentage pulse duration of a signal-is displayed on the
LCDin%
That is: Pulse duration
Duty cycle (%) = x 100
Cycle duration
Notes :
The applied frequency must remain constant during the duty cycle
measurement. Change -over between voltage, frequency and duty cycle
factor measurement is done as described in the preceding section.
15. Temperature measurement
The RISH Multi 12S...16S allows you to measure temperature with
Pt100 and Pt1000 temperature sensors in the range
from - 200 (- 100)
0
C...+850
0
C.
Set the function selector switch (6) to " W"
Connect the sensor to the two unblocked terminals.
Briey press the yellow multifunction pushbutton (5).
The multimeter switches to temperature measurement, it
automatically detects the connected sensor (Pt100 to Pt1000) and
shows the measured temper ature in
0
C on the digital display.
Notes:
This measurement automatically considers the lead resistance of
temperature sensors which are available as accessory .
It is not possible to switch over to temperature measurement when the
30W
Sensor lead resistance up to 50 W
Lead resistance of sensors having a value differing from that of
W
Briey press the yellow multi-function pushbutton (5) again.
The LCD now displays the resistance value which the multimeter
automatically considers after selecting the temperature measuring
range. We can recognise that this is the resistance correction value
on the temperature measuring range. The ’’
0
C’’ character is
simultaneously shown on the display.
You can set the lead resistance correction value as follows:
Press the DATA--MIN/MAX pushbutton (3) to increment the value, or
the AUTO/MAN pushbutton (4) to decrement the value. Each time
the pushbutton is briey pressed, the value changes by one digit.
Briey press the yellow multi-function pushbutton (5) again.
The LCD displays the measured temperature. The ashing decimal
point shows you that we have entered a correction value for the lead
resistance. The correction value is retained as long as multimeter is
switched on.
sensors can be considered up to a value of 50 as follows:

16
Each time the yellow multi-function pushbutton (5) is briey pressed,
the display changes between measured temperature and correction
value of the lead resistance.
We can exit the temperature measurement function
by pressing the yellow multi-function switch (5) longer, this is
conrmed by the two sound signals.
by changing the function selector switch.
Note:
For the lead resistance, the actual value measured on the digital
multimeter should be taken as correction value and not any specied
value.
16. Computer interface via RS 232C
The ZIEGLER Multi S multimeters are tted with a serial RS-232C interface
for transmission of measured data to computer. The measured values
are optically transmitted through the case with infrared light to an interface
adapter which is attached to the multimeter. The measured data is passed
to the computer via a cable.
Switching the interface ON
When switching on the multimeter, press the "ON/OFF" pushbutton
(2) and the " DATA--MIN/MAX" pushbutton (3) together.
With interface switched ON, automatic turn-OFF of the meter is
inactive. This is shown on the LCD (1) by ashing of the (8) symbol.
The ’’DATA " function cannot be activated.
Interface packs as accessories
Interface adapter with memory :
By using this adapter it is possible to store the measured data without
interfacing the multimeter to the computer. This stored data can be
transferred later on to a computer. For establishing a powerful multimeter
system you can connect upto ten multimeters ofine. Online connection
upto six multimeters to the computer is possible via memory adapter.
The interface packs include the adapters, the necessary connection
cables and the " ZIEGLER com 100 " data acquisition and evaluation software
with operating instructions.
RISH com 100 software
The ZIEGLERcom 100 software package corsists of a WINDOWS version.
With ZIEGLER com 100, you can simultaneously access, store, display
and document the measured data of several ZIEGLER Multi S multimeters.
The measured values are presented :
As digital display and analog indication similar to that of the
multimeter. (up to 4 multimeters)
In traces (XY and Yt) as on a 4-channel recorder.
In tabular form (data logger: upto 10 channels).
The measured data is stored in ASCll format for further processing.
For the use of ZIEGLER com 100, the following requirements must be met:
ON
13
Zero adjustment on the 30 W measuring range
When measuring small resistance values on the 30 W range, you can
eliminate the resistance of the leads and contact resistance by zero
adjustment.
Connect the test leads to the multimeter and join the free ends.
Briey press the yellow multi-function pushbutton (5). The meter
acknowledges zero adjustment by a sound signal, the LCD shows
"00.00"(+1digit) and the decimal point ashes. The resistance measured
at the instant the pushbutton is pressed is used as reference value
(max.200 digits) It is automatically deducted from the values measured
thereafter. Zero adjustment can be cleared.
By pressing the yellow multifunction pushbutton (5) for a long time and
is acknowledges by two sound signals.
By switching the multimeter OFF.
11. Diode test and continuity test
Verify that the device under test is electrically dead. External voltages
would falsify the measured results!
Set the function selector switch (6) to " "
connect the device under test as shown.
Forward direction and/or short circuit:
The multimeter displays the forward vol tage in Volts. As long as the voltage
drop does not exceed the maximum display value of 1.999V, you can also
rest several series-connected elements or reference diodes with small
reference voltage.
Reverse direction or open circuit:
The multimeter indicates overrange "OL"
Note:
Resistors and semiconductor junction in parallel with the diode falsify the
measured results!
Diode test and continuity test with buzzer
With the "buzzer" function selected, the meter emits a continuous sound
signal on the range 0...approx. 1V.
To switch the buzzer ON:
Briey press the yellow multi-function pushbutton (5).
The multimeter acknowledges turn-ON with a sound signal. At the same
time, the symbol (18) appears on the LCD.
To switch the buzzer OFF
Briey press the yellow multi-function pushbutton (5) again.
The multimeter acknowledges turn-OFF with a sound signal. The
symbol (18) disappears from the LCD.
When selecting the function "Diode test and continuity test’’ with the function
selector switch (6), the buzzer is always switched OFF. Repeated brief
pressing of the multifunction pushbutton (5) alternately switches the buzzer
on and off. When pressing the push button for a long time, the buzzer is
always switched OFF, this is acknowledged by the buzzer
sounding twice.
