2. Safety features and safety precautions
Please note the following safety precautions:
You have chosen a Clamp meter which provides you a very high degree of
safety. The digital Clamp meter / Digital multimeter manufactured and tested in
compliance with the safety standard IEC 61010-1:2010.
In case of incorrect use or careless handling, the safety of both user and clamp
meter are not assured.
For proper use and safe handling, it is absolutely necessary to read and
understand the operating instructions before using the clamp meter.
The clamp meter 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 AC and 1500V DC.
T ake into account that unexpected voltages can occur on devic e
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, i.e. no crac ked
insulation, no open circuits in the leads or connectors.
This clamp meter must not be used for measurements on circuits with
corona discharge (highvoltage).
composite voltages may exist there.
Be particularly careful when measuring on HF circuits. Dangerous
Measurements under moist environmental conditions are not permitted.
For safe voltage measurements in power systems
1500V DC, we recommend the
HV 30 measuring adapter, which is
available as an accessory.
Its internal resistance limits the measuring current in the case of
overvoltage, incorrect operation and safely suppresses sparking
from spark gap. Also refer to Section "8.1 Voltage measurement
on electrical systems up to
1000V AC and 1500V DC
with HV 30
Do not overload the measuring ranges beyond their allowable
capacities. Limit values are given in specifications. Ref. Chapter 16.
Please verify the performance of clamp meter after repairing
of the meter, before using it for actual measurement.
Do not use the clamp meter if obvious wear in jaw opening
is visible.
Protection provided by the digital clamp meter may be impaired if
the clamp meter is not used in a manner
manual.
specified in this user
Operators must use individual protective equipment if
hazardous live parts of installation could be accessible.
Keep hands/fingers behind the edge that separates rotating
jaws with hand held part(22). This is the limits of the hand
held part during measurement.

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
a qualified person who understands the danger involved.by

Disconnect the clamp meter from the measuring circuit before
you open it, and see section "18. Maintenance".
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.
How to prevent automatic TURN-OFF
In order to prevent automatic "TURN OFF" select "CONTINUOUSLY
ON" mode. For this, press

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

4.1 Autoranging
The multimeters feature autoranging for all measuring ranges with the
exception of the 30mV ,300mV ranges. 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
The meter switches automatically to:

4.2 Manual range selection
You can switch OFF autoranging and select the ranges manually
according to the table on the following page.
Manual mode is switched OFF when push button AUTO/MAN is pressed (4)
for approximately 1s, when the function selector switch (6) is operated,
or when the meter is turned OFF and ON again.
When switching back to autoranging from 30mV or 300mV ranges,

5.1 Digital display
The digital display (9) shows the measured value with correct location of decimal
point and sign. The selected measuring Unit(12)and the function(11)
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 3099
(on the range :1999),is exceeded then"OL"is displayed.
With V and Ω measurements, the digital display is updated two times
per second.
5.2 Analog indication
The analog indication with pointer presentation gives the dynamic
response of a moving-coil movement and is updated 20 times per second,
when measuring V and
Ω. Analog indication is of particular advantage
when observing variations of measured values and for calibration
procedures.
The analog indicator has its own polarity indication. When measuring
DC quantities, the analog scale(15) has a negative range of 4 scale
divisions so that variations of the measured values around" zero"canbe
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).
The instrument is provided with user selectable Backlight for taking
measurements in poor lighting conditions/darkareas.
Switching the Backlight ON
By pressing "AUTO/MAN"and"HOLD" keys simultaneously
the Backlight can be switched ON.
Switching the Backlight OFF
By pressing "AUTO/MAN" and "HOLD" keys simultaneously
the Backlight can be switched OFF.

The HOLD function allows to automatically hold the measured values.
The meter holds the measured value on the digital display with a sound
signal and displays “ HOLD ” on LCD display (10). The probes or clamp

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
Clamp Meter
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 measu ring
range prior to activating the MIN/MAX function.
With the function activated, you can select the measuring ranges
manually, if you switch to another range, the stored MIN/MAX values are
cleared.
