8.6 Voltage Measurement
Be aware of the fact that dangerous voltage spikes are
not displayed during measurement with the low-pass fil-
ter. Measure voltage without the low-pass filter first, in
order to be able to detect any dangerous voltages.
Rotary selector switch position “RISO” is available for the
detection of interference voltage during insulation resis-
tance measurement. Use switch position V , V or V
in order to perform precise voltage measurements.
8.6.1 Alternating Voltage and Frequency Measurement V AC and
Hz with Selectable Low-Pass Filter
➭ In accordance with the voltage or frequency to be measured,
turn the rotary switch to V~ or Hz.
➭ Press the MENU key.
➭ Press the “Setup for present measurement” softkey.
➭ Make sure that the Clip parameter is set to Off. Otherwise all
measured values are displayed in amperes, corrected by the
amount resulting from the selected transformation ratio for an
interconnected current clamp sensor.
➭ The display is returned to the measurement view by pressing
the ESC key twice.
➭ Repeatedly press the Func softkey until the desired measuring
function is displayed.
➭ Connect the measurement cables as shown.
The “” connector jack should be grounded.
V AC – Voltage Measurement
An intermittent acoustic signal warns the operator if the
measured value exceeds the upper range limit in the
1000 V range.
Make sure that a current measuring range (“A”) has not been acti-
vated, 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 softkey until unit of measure VAC or
VAC Fil appears at the display.
➭ If necessary, conduct zero balancing by pressing the Zero key
(see section 8.6.4 for description).
Hz – Frequency Measurement
➭ Connect the measured quantity in the same way as for volt-
age measurement.
➭ Manually select the measuring range for the voltage ampli-
tude. When the instrument is switched to frequency measure-
ment, the previously selected voltage measuring range
remains active.
➭ Repeatedly press the Func softkey until unit of measure Hz ap-
pears at the display. Lowest measurable frequencies and
maximum allowable voltages are listed in section 10, “Charac-
teristic Values”.
VAC Fil – Voltage Measurement with Low-Pass Filter
Be aware of the fact that dangerous voltage spikes are
not displayed during this type of measurement (see also
“Voltage Comparator”).
Measure voltage 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.
Fil appears at the display in order to indicate that the low-pass fil-
ter is activated. The multimeter is automatically switched to man-
ual measuring range selection.
Specified measuring accuracy is not reached with signals of
greater than 500 Hz when the filter is active.
