Function Buttons
Correction of Zero correction for DC measurement
This function allows the user to set the magnetization effects to zero
when measuring DC. It must be performed after each high amplitude
current measurement.
With no conductor inserted into the clamp, press and hold the "Z / F"
key (approx. 3 seconds) until a beep sounds and the ZERO symbol
appears on the display.
Function selector (for secondary functions)
Press the "Z / F" key to switch the respective secondary function
between the different measurements for the applications accessible|
via the function switch such as between AC and DC.

Press the "MAX / MIN" button to display the minimum or maximum
values one after the other. Press and hold the button for more than
2 seconds to exit MAX / MIN mode.
Backlight: Press the button to activate / deactivatethe the background!
lighting. It turns off automatically after about 10 seconds of inactivity,|
Work light: Press and hold this button for more than 2 seconds to
switch the work light on or off.
HOLD: The HOLD function holds the currently displayed measured
value on the display so that it can be read or logged in peace.
Make sure that the function is deactivated at the start of the test.
Otherwise an incorrect measurement result will be simulated!
NCV (non-contact AC voltage detection):
Press and hold the button for more than 2 seconds to activate or
deactivate the NCV function.

Other Functions
AC voltage measurement with low-pass filter "LPF"
The"LPF" function allows the clamp meter to filter interfering signals of over 60
Hz. These signals can lead to inaccurate measurements. The meter filters these
signals and only measures the voltage signal.

Measurement with LPF: 60 e
Set the rotary switch to 600A, 60A or V. ©
Press the "Z / F" button three times until 7 appears on the display.
Now you can connect test leads and start measurement.
AThe LPF function is only possible in AC measurement mode.
High-Impedance Voltage Measurement
High Impedance means high electrical Impedance. This is used to denote the
input Impedance or output Impedance of electrical circuits and devices in particular.
When measuring in the circuit, this has only a minor impact on the performance
of the circuit, particularly in the case of sensitive electronic circuits or control
circuits.

Low impedance voltage measurement (LowZ)
LoZ mode allows you to measure AC voltages with a low impedance (approx.
300 kQ). In this mode, the multimeter lowers the internal resistance to prevent
‘phantom’ voltage readings. As a result, the circuit is more heavily loaded than
in the standard measuring mode.
Set the rotary switch to "LowZ" to use the function.
The LowZ voltage measurement must not exceed 600 V. Due to the reduced
impedance, this measurement function is not suitable for continuous measurement.
The measurement duration of 1 minute must be observed.

Operating Instructions
Insert and replace batteries
Replace the batteries immediately when the
symbol “C3” appears in the display. Disconnect the
meter from the power source. Remove the test leads from
the measuring device, loosen the screws on the back and
remove the lower half of the housing, replace the old batteries
and screw the cover back on.
Turn on/off the meter
The device is switched on when the rotary switch (5) is set to a measuring function.
When the rotary switch is set to OFF, the measuring device is switched off.
Automatic shutdown
No operation in 15 minutes, the clamp meter beeps 3 times. Without further
operation, the clamp meter beeps again and switches off automatically.
Press any key to restore the clamp meter to operating status. The symbol &
appears on the display.
To deactivate the automatic switch-off, hold down the "Z / F" key for more than 2
"

seconds and switch on the clamp meter at the same time. The symbol &
disappears. Restart after switching off the meter, the automatic switch-off can be
restored.
Auto-ranging
The meter automatically selects the measuring range that is best suited for the
measurement performed. The measuring unit and resolution are adjusted at the
same time.
AC Zero Input Behavior of True-rms Meters
Unlike averaging meters, which can accurately measure only pure sinewaves,
True-rms meters accurately measure distorted waveforms. Calculating True-rms
converters require a certain level of input voltage to make a measurement. This
is why ac voltage and current ranges are specified from 5 % of range to 100 % of
range. Non-zero digits that are displayed on a True-rms meter when the test
leads are open or are shorted are normal. They do not affect the specified ac
accuracy above 5 % of range.
Connecting Test Leads
Do not test if leads are improperly seated. Results
could cause intermittent display readings. To ensure
proper connection, firmly press leads into the input
Jjack completely.

Making Measurements
AC/ DC Current measurement
The current is measured via the current clamp (2). The sensors in the current
clamp detect the magnetic field created by current-carrying conductors. You can
take measurements on insulated and not insulated conductors.
The test leads should be disconnected from the measuring device when measuring
current. Proceed as follows to measure the current:
1. Turn the rotary switch to the correct current setting (60A / 600A). "DC" appears
on the display. Press the "Z / F" button, AC is shown on the display.
2. Press the clamp release lever and open the clamp.
3. Grasp the individual current conductor to be measured and close the current
clamp again. Position the conductor in the middle between the two triangular
position symbols on the pliers.
» Do not use the current clamp to surround more than one conductor.
» If the supply and return conductors (e.g. L and N) are measured, the currents
will cancel each other out and no measurement will be displayed. The cables of
household appliances usually contain L and N conductors. A cable separator is
required to measure with the current clamp.
13

» If several supply conductors (e.g. L1 and L2) are measured, the currents add up.
» Center the conductor through the current clamp (above the markings)
» Hold your fingers behind the tactile barrier.
4. The measured current is shown on the display. If current> 3A, the orange
display lights up.
5. During AC current measurement, press "Z / F" to display the frequency value
or use the LPF function measurement.
14

Voltage Measurement V (DC / AC)
AVoltage above 600 V cannot be measured! When measuring high voltage, pay special
attention to safety to avoid electric shock or injury.
1. Set the rotary switch to V. Press the "Z / F" key to change the AC or DC voltage
measurement.
2. Plug the black test lead into the COM socket and the red test lead into the INPUT
socket.
3. Then bring the test probes into contact with the points to be measured.
4. Read the result on the display. If the voltage is> 80 V, the orange display lights up.
5. When measuring the AC voltage, press "Z / F" to display the frequency result or the
result of the LPF function.
6. If you are measuring low impedance, turn the rotary switch to the Low-Z position and
press the "Z / F" button to switch between AC and DC voltage.
