1. Safety features and safety precautions
You have chosen a meter which offers you a very high degree of safety.
This meter Gamma 20 is manufactured and tested in compliance with the
safety standard IEC 61010-1:2001 / DIN EN61010 -1:2001.
In case of incorrect use or careless handling, the safety of both user and
multimeter is not assured.
To maintain the safe and proper condition of the meter and to ensure their safe
operation, it is absolutely necessary to carefully and completely read these
operating instructions before using any meter. These instructions must be
followed in all respects.
For your safety and for protection of the meter, this meter is fitted with an
Automatic terminal Blocking System It is coupled with the function selector
switch which blocks the terminal sockets not necessary for measurement.
Please note the following safety precautions:
lThe meter must be operated only by persons who understand the
danger of shock hazards and know how to apply safety precautions.
Shock hazards exist wherever voltages of more than 30V (TRMS) can
appear.
lDo not work alone in shock hazardous environment while carrying out
measurement.
lThe maximum permissible voltage between terminal Socket (7) and
ground is 1000 V.
lTake into account that unexpected voltages can occur on device under
test (e.g. defective instrument). Capacitors may be charged to a
dangerously high voltage, for instance.
lVerify that the test leads are in good condition, e.g. no cracked
insulation, no open circuits in the leads or connectors.
lThis meter must not be used for measurements on circuits with corona
discharge (high voltage).
lBe particularly careful when measuring on HF circuits. Dangerous
composite voltages may exist there.
lMeasurements under moist environmental conditions are not Permitted.
lDo not exceed the permissible overload limits of the measuring ranges.
See Table “Measuring ranges” under “15. Specifications”.
lAll current measuring ranges, are fused. The maximum permissible
voltage of the measuring circuit (=nominal voltage of the fuse) is1000 V
AC/DC in “mA” ranges, “A” ranges.
lYou must only use the meter in power systems, when 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 1000V.
For safe voltage measurements on power systems, up to 1000V we
recommend the KS 30 measuring adapter, which is available as accessory.
Its internal resistance limits the measuring current in the case of over voltage
and incorrect operation and safely suppress sparking from spark gaps. Also
refer to Section “7.1Voltage measurement on electrical systems up to 1000V
with the KS 30 measuring adapter”.
Fuse replacement
ŸOpen the meter same as for battery replacement
ŸRemove the blown fuse, e.g. with the aid of a probe, and replace it with a
new one.
Permissible types
Øfor current measuring ranges up to 300 mA:
FF (UR) 1.6A /1000 V AC/DC; (10 KA); 6.3 mm x 32 mm
Øfor the 10A current measuring ranges:
Type FF(UR) 16A/1000V AC/DC; (30kA); 10mmx38mm
Caution :
Absolutely verify that only the specified fuse is installed!
If a fuse of other cut-out capacity, other nominal current or other switching capacity
is used, a dangerous situation exists for you, and there is danger of damaging
protective diodes, resistors or other components.
The use of mended fuses or shorting of the fuse holder is not permissible.
16.3 Case
Special maintenance of the case is not required. Take care that the surface
between the connection sockets is clean. For cleaning take a moist cloth.
Avoid scrabbing.

18. Appendix
18.1 AC current measurement with (clip-on) current transformers
18.1.1 Transformer 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 meter and the secondary
winding of the transformer connected to the meter form an 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.
18.1.2 Transformer output V
Several transformers are fitted with a voltage output (designation mV/A). The
secondary output must therefore be connected to the connection sockets ^
and V.

How to prevent automatic TURN-OFF
Switch your meter to "CONTINUOUSLY ON" mode.
ØTo do this, press y "ON/OFF"
pushbutton (2) together. The function "CONTINUOUSLY ON"
is shown on the LCD (1) by the symbol
ellow multi-function pushbutton (5) and the

ON
Automatic TURN - OFF
The meter turns off automatically, when the measured value remains constant
(variations of the measured value < + 2digits) for about 10 minutes and when
neither a pushbutton nor the function selector switch is operated during that
time.
Note:
Electric discharges and high-frequency interference may cause incorrect
information to be displayed and block the measuring process. Reset the meter
by switching it OFF and ON again otherwise, check the battery connections.
Disconnect the meter from the measuring circuit before you open it, and see
section "16.Maintenance"!
Repair, replacement of parts and calibration
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 qualified
person who understands the danger involved.
Fausts and extraordinary stress
When it must be assumed that the safe operation is no longer possible,
take the meter out of service and secure it against accidental use.
It is assumed that safe operation may not be possible,
lwhen the meter shows obvious signs of damage,
lwhen the meter no longer functions correctly,
lafter prolonged storage under adverse conditions,
ldue to severe stress during transportation.
2. Switching the meter "ON”

The function selector switch (6) is coupled with the Automatic terminal
Blocking System which allows access only to two correct sockets for each
function. Prior to switching to the "mA" 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 non permissible functions.
Function and range selection
3.1 Autoranging
The multimeters feature autoranging for all measuring ranges except for
temperature measurement and diode test. Autoranging is automatically
selected after switching the Multimeter ON. According to the measured
quantity applied, the multimeter automatically selects the measuring range
which gives the best resolution. When switching to frequency measurement
the previously selected voltage measuring range is maintained.
The meter switches automatically to :
The next higher range at + (309999 digits + 1digit)
the next lower range at + (28000 digits - 1 digit)
For capacitance measurement the change of
switchover occurs at (2999 digits + 1 digit)
and 280 digits-1 digit
Turning the multimeter OFF

4.1 Backlit
The instrument is provided with user selectable Backlit for
measurements
in poor light conditions or dark area.
Switching the Backlit ON and OFF:
By pressing “AUTO/MAN” and “DATA/MIN/MAX” keys simultaneously
the Backlit can be switched ON.
And by pressing the same keys simultaneously Backlit can be switched
OFF.
Although the main display is activated immediately after the multimeter is
switched on, the two sub-displays must be activated with the MIN/MAX
key. This prevents the contineous display of an undefined condition which
was present at the start of measurement, e.g. open-circuit, as a maxi-
mum value.
The three digital displays, one main display and two sub-displays, show the
measurement value with correct decimal point and sign. The selected unit of
measure and the current type are also displayed. A minus sign appears in
front of the number for the measurement of zero-frequency direct quantities,
if the positive pole of the measured quantity is applied to perpendicular input.
“OL” (overload) is displayed, if the actual value falls above the measuring
range upper limit for the following measured quantities: VDC, IDC,
VAC,IAC,mAAC,mADC,F ‘Ω’,Hz:.
Refreshing of the digital display occurs at different intervals for the various
measured quantities ..

Measurement values can be automatically “frozen” with the data function.
This can be especially useful when your full attention is required for testing
the measuring point with the test probes.
After the measurement value has been acquired, and the appropriate
“condition” has been fulfilled according to the following table, the
measurement value is displayed in the left hand sub-display and two acoustic
signal sounds. At the same time “MAN” appears and indicates that the
measuring range is now set. The test probes can now be removed from the
measuring point and the measurement value can be read from the sub-
display. If the measurement value lies below the limit value shown in the
table, the instrument is reactivated for the storage of a new value; the “HOLD”
display blinks.

observation of measured quantities.
1.If the DATA/MIN/MAX key is activated twice, current MIN and MAX values are
displayed at the sub-displays.
2.Press the DATA/MIN/MAX key again to display the MIN value and the time of
occurrence.
3. If the DATA/MIN/MAX key is once again activated, the MAX value and the
corresponding time of occurrence are displayed.
MIN and MAX values are deleted by pressing and holding the DATA/MIN/MAX key
(approx. 1 s), by activating the rotary switch or by switching the instrument off and
back on again.
1) Reactivate by falling below the specified limits of the measured value.
2) When storing a value for the first time twice sound signal is generated.
For following “Holds” only twice if actual hold value differs from first
stored value by less than 100 digits.
The analog indication is not influenced by data HOLD. You can still read the
actual measured value. Note that with a “held” digital display, the location of
the decimal point is also held.
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” push button (3) is
pressed for approximately 1 s, when the function selector switch (6) is
operated, or when meter is turned OFF and ON again.

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 20 A and when
the nominal voltage of the system does not exceed1000V.
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 and 10 mA ranges, 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.
lThe current measuring ranges up to 10A are protected by a16A/1000V
fuse. The cut-out capacity of the fuse is 30kA at a nom. voltage of
1000V and ohmic load.
lA 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"
lAfter a fuse has blown, eliminate the cause of the overload before using
the meter again !
lReplacement of the fuses is described in section ’’ 16. Maintenance’’.
