5.1.2 Alternating Voltage and Frequency Measurement V AC and Hz
with Selectable Low-Pass Filter
➭ Set the CL iP parameter to 0FF in the current clip setup menu.
Otherwise all measured values are displayed in amperes,
corrected by the amount resulting from the selected transfor-
mation ratio for an interconnected clip-on current sensor.

➭ In accordance with the voltage or frequency to be measured,
turn the rotary switch to V~ or Hz/%.
➭ Connect the measurement cables as shown.
The “
⊥” connector jack should be grounded.
Voltage Measurement
Note
An intermittent acoustic signal warns the operator if the
measured value exceeds the upper range limit in the 1000 V
range.
measured value exceeds the upper range limit in the 1000 V
range.
Make sure that a current measuring range (“A”) has not been
activated, when the multimeter is connected for voltage
measurement! If the fuse’s blowing limits are exceeded as a
result of operator error, both the operator and the instrument are
in danger!
➭ You can switch back and forth between voltage measurement
activated, when the multimeter is connected for voltage
measurement! If the fuse’s blowing limits are exceeded as a
result of operator error, both the operator and the instrument are
in danger!
➭ You can switch back and forth between voltage measurement
with and without low-pass filter.
➭ Repeatedly press the FUNC | ENTER multifunction key, until
the V or V/Fil unit of measure appears at the display.
Frequency Measurement
➭ Connect the measured quantity in the same way as for voltage
➭ Connect the measured quantity in the same way as for voltage
measurement.
➭ Manually select the measuring range for the voltage amplitude.
When the instrument is switched to frequency measurement,
the previously selected voltage measuring range remains active.

➭ You can switch back and forth between frequency
measurement with and without low-pass filter.
Repeatedly press the FUNC | ENTER multifunction key, until
the Hz or Hz/Fil unit of measure appears at the display.
Lowest measurable frequencies and maximum allowable
voltages are included in chapter 8, “Technical Data”.

Measurement with Low-Pass Filter
Attention!
!
Be aware of the fact that dangerous voltage spikes are not
displayed during this type of measurement (see also “Volt-
age Comparator”. We recommend measuring voltage
without the low-pass filter first, in order to be able to detect
any dangerous voltages.
displayed during this type of measurement (see also “Volt-

without the low-pass filter first, in order to be able to detect
any dangerous voltages.
A 1 kHz/-3 dB low-pass filter can be activated if required, in order
to
filter out capacitively induced high frequency pulses of greater
than 1 kHz, for example when performing measurements at
cables, i.e. undesired voltages of greater than 1 kHz can be
suppressed.
