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 influence 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.
1) Reactivated by falling below the specified limits of the measured value.
2) With the exception of the ranges 30 mV and 300 mV.
As long as the DATA hold function is active, manual range selection is not
possible. The DATA hold function is switched OFF, when,

5.3. Backlit
The instrument is provided with user selectable Back-lit for taking
measurements in poor lighting conditions/ dark areas.
Switching the Backlit ON
By pressing “AUTO/MAN” and “DATA/MIN/MAX” keys simultaneously the
Backlit can be switched ON.
Switching the Backlit OFF
By pressing “AUTO/MAN” and “DATA/MIN/MAX” keys simultaneously the
Backlit can be switched OFF.
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
specified in the table, the meter is reactivated for a new storage.
The analog indication is not influenced by the DATA hold,
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.

8.1 Voltage measurement on electrical systems up to 1000V
with the KS30 measuring adapter.
On low-Voltage systems, transient over voltages 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..
9. Current Measurement
EFirst disconnect the power supply to the circuit being measured and/
or to the load, and discharge all capacitors within that circuit.
ESelect the DC current measuring ranges as described in section 4.1
EWith the function selector

ESelect the function corresponding to the measured quantity by briefly
pressing the yellow multi-function pushbutton (5). Each time the
pushbutton is pressed, alternate switching takes place between DC
and (DC + AC).
The change-over is acknowledged by a sound 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+AC 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 + AC and acknowledges this
by two sound signals.

that the connections are tight (without contact resistance).

Notes on Current measurement :
lThe multimeter must be used only in the power systems, where the
current circuit is protected by a fuse or a circuit breaker of 2 A and when
the nominal voltage of the system does not exceed1000V AC/DC.
lMake 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.
lOn the 300 mA an Intermittent sound signal warns you, when the
Measured value exceeds the upper range limit.
lThe current measuring ranges upto 300 mA are protected to a short
circuit current of 25 A by a fuse 1.6 A/1000V AC/DC in conjunction,
with power diodes. The cut-out capacity of the fuse is 10kA at a rated
voltage of1000V AC/DC and ohmic load.

†Voltage displayed after measurement is the voltage present on the device
under test (DUT) due to conductor capacitance.
†Discharge the device under test (DUT) by turning the function selector
switch to “V1M ”.Ω
†Contact with DUT must be maintained. Reduction of voltage can be
observed directly on LCD.
CAUTION !!!
Do not disconnect DUT until voltage has dropped below 25V.
16.5 Evaluation of Measurement Values:
In order to assure that insulation resistance does not violate lower limit values,
the instrument’s intrinsic and influence errors must be taken into
consideration.
The minimum values of insulation resistance can be determined by the
following table, which must be displayed under consideration of maximum
operating error for this meter (under nominal conditions of use) in order to
assure that the required limit values are not violated.

ENOTE !!!
The instrument batteries are rapidly depleted during insulation resistance
measurement. Only press and hold the multifunction key as long as is
necessary to take the reading. Continuous measurement as described
below should only be performed if absolutely necessary. Use only Alkaline
manganese batteries in accordance with IEC6 LR03.
High Voltage
Do not touch the conductive ends of the test probes after insulation
measurement has been activated at the instrument. A current with a
value of 2.5 mA (limited by instrument ) may flow over your body, and
although this is not life threatening, the electric shock is distinctly
perceptible. If you are taking measurement at capacitive DUT, for
example a cable, it may be charged with as much as 1000 V,
depending upon the selected nominal voltage. Touching the DUT may
be life threatening.
