5.7 Voltage and frequency

Voltage measurement should be carried out often while dealing with electric installations
(carrying out different measurements and tests, looking for fault locations, etc.).
Frequency is measured for example when establishing the source of mains voltage
(power transformer or individual generator).
How to perform voltage and frequency measurement
Select VOLTAGE function with the function selector switch. The following
Step 1
menu is displayed:
Figure 5.43: Voltage and frequency measurement menu
Connect test cable to the EurotestXE 2,5 kV instrument.
Follow the connection diagram shown in figure 5.44 to perform voltage and
Step 2
frequency measurement.
