5.3.3 Measuring voltage and frequency
1. Connect the instrument according to the
diagram opposite.
2. Select any position with the switch
3. Read off all the measurements using the
“MORE” button.
4. To save or print out voltages and
frequencies, a live TEST (RCD, earth, loop,
phase rotation) must be run with the TEST
button; voltages and frequencies are always
saved or printed with the test made.
WARNING!: Voltages and frequencies saved by a TEST can only be displayed whilst printing out
or transferring measurements stored in memory to a PC and EXCEL; The
environmental parameters of measurements (voltages, frequency, current) cannot
be displayed on the LCD screen in Memory Recall mode): see chapter 6.2.

5.4 Measuring current and leakage current with a clamp
This function is used to measure very low currents of around a few mA (fault currents, leakage currents,
etc...) up to currents of around 300 A AC.
Using a clamp gives the best safety possible during measurement.
5.4.1 Description of the function
A current clamp with a 1000:1 transformation ratio is connected via an operational amplifier input (OP).
The resulting power-less flow of current considerably broadens the clamp’s measurement range, enabling
even traditional high current measurement clamps to measure down in the mA region.
