1 Introduction
Thank you very much for selecting our multimeter. These multimeters are manufactured as per IS 13875 and DIN 43751.
2 Safety Features and Safety Precautions
You have chosen a multimeter which provides you with a very
high degree of safety. The analog-digital multimeters are manufactured and tested in compliance with the safety standard
IEC 61010-1:2010/ DIN EN 61010-1:2011. In case of incorrect use or careless handling, the safety of both user and multimeter is not guaranteed.
For proper use and safe handling, it is absolutely necessary to read
and understand the operating instructions before using the multimeter.
For your safety and protection, the multimeters are fitted 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 voltage of more than 30 V (TRMS) is present.
• Do not work alone in shock hazardous environment while
carrying out measurements.
• The maximum permissible voltage between terminal socket
(7) and ground is 1000 V.
• Take into account that unexpected voltages may occur on
devices 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.
6 GMC-I Messtechnik GmbH
• 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.
• Do not overload the measuring ranges beyond their allowable capacities. Limit values are given in specifications, see
section 16.
• All current measuring ranges are protected with a fuse. The
maximum permissible voltage of the measuring circuit (nominal voltage of the fuse) is 1000 V AC/DC in the „mA“ and „A“
ranges.
• Protection provided by the digital multimeter may be
impaired if the multimeter is not used in a manner specified
in this user manual.

3 Switching the Multimeter „ON“
Battery
Your multimeter works on 2 x AA size alkaline manganese batteries per IEC LR6. They are provided with the multimeter.
Before you use the multimeter for the first time or after storage,
refer to section 17.1. Set the rotary knob (6) to other than the
„OFF“ position to switch the multimeter ON. Switch „ON“ is
acknowledged by an acoustic signal. All segments of the LCD
will be displayed as shown on page 2.
Note:
Electric discharges and high-frequency influence may cause
incorrect information to be displayed and block the measuring
process. Reset the multimeter by switching it OFF and ON
again. Otherwise, check the battery connections. Disconnect
the multimeter from the measuring circuit before you open it,
and refer to section 17.
Automatic Meter-OFF (MoFF)
The digital multimeter has a default auto meter-off function. If
the multimeter is idle for more than 15 minutes, the multimeter
automatically turns the power off. When MoFF happens, the
state of the multimeter is saved. The „MoFF“ (16) sign on the
LCD panel indicates whether the MoFF is enabled or not. In
some cases, the user might want to disable this feature. Power
ON the multimeter by pressing any of the push functions
except for the HOLD (8) and multifunction (5) pushbuttons.
After auto meter-off, pushing any of the push functions or
changing the rotary switch mode can turn on the multimeter
again. If the multimeter is re-powered by changing the rotary
mode, the saved state is cleared. If the multimeter is re-powered by push functions, the chip restores the saved state and
enters HOLD mode. The LCD displays the saved value.
Turning the multimeter OFF
To turn OFF the multimeter, set the rotary knob (6) to the „OFF“
position.
GMC-I Messtechnik GmbH 9
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 system prevents accidental switching to non permissible functions.
4.1 Switching the Measuring Ranges
The 660 mVAC and 660 mVDC measuring ranges are not
automatically selected when the multimeter is switched ON.
The above ranges can only be selected manually with the
„AUTO/MAN“ key.
4.2 Auto / Manual Ranging
The multimeter features auto ranging for all measuring ranges
with the exception of the °C, °F, continuity, Diode, %, AAC,
ADC. 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. You can switch OFF autoranging and select the ranges manually according to the table
shown in this section. Manual mode is switched OFF when
pushbutton AUTO/MAN is pressed (4) for approximately 1 s, or
when the function selector switch (6) is operated, or when the
multimeter is turned OFF and ON again.

5 Liquid Crystal Display (LCD)
5.1 Digital Display
The main digital display (10) shows the measured value with
correct location of decimal point and sign. The selected measuring unit (15) and the function (21) are simultaneously displayed. When measuring DC quantities, a minus sign appears
in front of the digits, when the positive pole of the measured
quantity is applied to the „ “ input terminal. When upper range
limit 6600 (on the range :1999) is exceeded, „OL“ is displayed. The digital display is updated 2.8 times per second.
The digital sub-display (14) shows the measured value with
correct location of decimal point and sign. The main purpose
of the two digital displays is to display simultaneous measurement as mentioned below:
GMC-I Messtechnik GmbH 11
Main Display Sub-display

5.2 Analog Indication
The analog indication with bar graph is updated 28 times per
second. Analog indication is of particular use when observing
variations of measured values. The analog bar graph (13) has
its own polarity indication in measuring DC quantities, when
the positive pole of the measured quantity is applied to the „ “
input terminal. Analog bar graph has 65 scale divisions so that
variations of the measured values around „zero“ can be
observed exactly. The overrange is indicated by the right triangle (12) when measured value is > 6600 counts (for measurement > 1999).
5.3 Backlight
The instrument is provided with user selectable backlight for
taking measurements in poor lighting conditions/dark areas.
Switching the backlight ON
By pressing (9) key, the backlight can be switched ON for
60 s.

6 HOLD and Delay Hold Feature
6.1 HOLD Feature
After pressing the „HOLD“ (8) button, the multimeter stops
updating the LCD panel. After enabling the HOLD function, the
multimeter switches from AUTO to the manual ranging mode,
but the measuring range remains the same.
6.2 Delay Hold Feature
The multimeter provides a delay HOLD feature. To activate the
delay HOLD feature, press the „HOLD“ (8) button for 2 seconds. The multimeter will wait for 6 seconds, then enters
HOLD mode. During the 6 second period, the HOLD symbol
on the LCD will blink and after 6 seconds, the multimeter will
hold the measured value present on the LCD. To exit the delay
HOLD function, either change range or press the „AUTO/MAN“
(4) or „HOLD“ (8) button again.
7 MIN/MAX Feature
With the MIN/MAX function, you can hold the minimum and
maximum measured value which has been applied to the input
of the multimeter after activating the MIN/MAX function. The
most important application is the determination of the minimum and maximum value for long-term monitoring of measured parameters. The actual measured value can still be
noted/read during this feature. Apply the measured quantity to
the multimeter 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. After
pressing MIN/MAX (3) for the first time, the sub-display shows
maximum value. The sub-display shows minimum value when
it is pressed again. The main display always shows the current
value in MIN/MAX mode. To exit from this mode, either press
and hold the MIN/MAX (3) button for longer than one second,
operate the function selector switch (6) or turn the multimeter
OFF and ON again. Pressing HOLD (8) in MIN/MAX mode
GMC-I Messtechnik GmbH 13
makes the multimeter stop updating the maximum or the minimum value.
Note
MIN/MAX function is available in all measuring ranges except in
Hz.
8 Peak Measurement
METRALINE DM 61 and 62 provide a peak hold function to
capture the maximum or minimum peak value. To enter peak
mode, press the PEAK (2) pushbutton for less than 1 second.
A self-calibration process will be executed automatically before
normal peak-hold operation. In peak mode, the main display
shows the current value of signal, and the sub-display shows
the PMAX or PMIN value which is selected by the PEAK key.
After pressing the PEAK (2) pushbutton for the first time, the
sub-display shows the PMAX value. The sub-display shows
the PMIN value when the PEAK (2) pushbutton is pressed
again. To exit the PEAK-hold function, either press the PEAK
key for more than 1 second, operate the function selector
switch (6) or turn the multimeter OFF and ON again.

According to the voltage to be measured, set the function
selector switch (6) to V AC or V DC. Connect the test leads as
shown. The „ “ socket should be connected to the lowest
potential ground available. In V AC mode, the main display
always shows voltage and the sub-display shows frequency.
Note
The 660 mV measuring ranges can only be selected manually
with the „AUTO/MAN“ (4) pushbutton.
Caution
Ensure that the current
measuring range („mA“ or
„A“) is not selected during
voltage measurement! If
the cut-out rating of the
fuses is exceeded due to
improper operation, a
dangerous situation may
occur!
GMC-I Messtechnik GmbH 15
10 Current Measurement
• First disconnect the power supply to the circuit being measured and/or to the load, and discharge all capacitors
within that circuit.
• With the function selector switch (6), select A for currents
> 660 mA and mA for currents ≤ 660 mA. When measuring current of unknown magnitude, select the highest measuring range first.
• Select the function corresponding to the measured quantity by briefly pressing the yellow multi-function (5) pushbutton.
• Each time the pushbutton is pressed, alternate switching
takes place between DC and AC. The change-over is
acknowledged by an acoustic signal.
• The symbols DC and AC (21) 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.
• Connect the multimeter in series with the load, as shown.
Ensure that the connections are tight (with least 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 1000 V AC/DC.
• Carefully secure the measuring circuit connections by
mechanical means so that they do not accidentally open.
The conductor cross sections and connection points
should be designed so as to avoid excessive heating.
• The current measuring ranges up to 660 mA are protected
against a short circuit current of 25 A by a 1.6 A/
1000 V AC/DC fuse in conjunction with power diodes.
16 GMC-I Messtechnik GmbH
The cut-out capacity of the fuse is 10 kA at a rated voltage
of 1000 V AC/DC and ohmic load.
• The 10 A current measuring ranges are protected by a
10 A / 1000 V AC/DC fuse. The cut-out capacity of the
fuse is 30 kA at a nominal voltage of 1000 V AC/DC and
ohmic load.
• Replacement of the fuses is described in section 17.
10.1 AC Current Measurement with (Clip-on) Current Transformer
10.1.1 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 multimeter, or a wrong connection, dangerously high voltages may occur at the connectors. Therefore,
make sure that the current circuit of the multimeter and secondary winding of the transformer connected to the multimeter
form an intact circuit. Connect the transformer to the and
mA or A sockets. 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.
Transformer output METRALINE DM 61
The METRALINE DM 61 shows the switching position and the
corresponding sockets. Connect a (clip-on) current transformer with a transmission ratio of 1000:1 to this socket. The
measured values are then displayed directly in the „A“ range.

17 Maintenance
Caution
Disconnect the multimeter from the measuring circuit before
you open it to replace the battery or the fuse!
17.1 Battery
Prior to initial start-up or after storage of multimeter, verify that
the batteries inserted in the multimeter do not leak. Repeat this
check at regular brief intervals. If the batteries are leaking,
remove them carefully and entirely with a moist cloth and install
new batteries before putting the multimeter back into operation. When the symbol „ “ (17) appears on the LCD (1),
replace the batteries as soon as possible. Although measurements can still be performed, a reduced measuring accuracy
must be taken into account in this case.
ates with 2 x AA size alkaline manganese batteries per IEC LR6.
Replacing the Battery
➭ Place the multimeter on its face, loosen the single screw on
the rear side and remove the battery cover.
Remove the batteries by levering out the negative pole of
the batteries with a screw
driver first. Otherwise, the
contacts of the positive pole
in the battery compartment
might be damaged and the
battery lead severed.
➭ Remove the batteries from the battery compartment and
replace them with new ones (for technical specifications
refer to sub-section „Power supply“).

32 GMC-I Messtechnik GmbH
Attention!
!
When inserting the batteries, begin with the positive
pole of the battery and fit the negative pole into place
afterwards, in order to avoid damage to the contacts of
the positive pole.
➭ Tighten the battery cover with the screw.
17.2 Fuses
The 10 A fuse protects the 10 A range, the 1.6 A fuse protects
the 66 mA, 660 mA current measuring ranges. When a fuse
blows, eliminate the cause of the overload before using the
multimeter again!
Replacing the Fuses
• Place the multimeter on its face, loosen the two bottom
cover screws on the rear and remove the bottom cover by
lifting it from the bottom.
• Remove the defective fuse from the fuse holders.
• Remove the blown fuse, e. g. with the aid of a probe, and
replace it with a new one.
• Tighten the bottom cover with the two screws.
Fuse types for current measuring ranges up to 660 mA:
– FF (UR) 1.6 A / 1000 V AC/DC; (10 kA); 6.3 mm x 32 mm
For 10 A current measuring range:
– FF (UR) 10 A / 1000 V AC/DC; (30 kA); 10 mm x 38 mm
Caution
It is imperative to ensure that only the fuses specified above
are 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 a risk of damaging protective diodes, resistors or
GMC-I Messtechnik GmbH 33
other components. The short-circuiting of the fuse holder is
