Voltage and frequency
Voltage measurements should be carried out regularly 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
Step 1
Select the
VOLTAGE
function with the function selector FCT key. The following
menu is displayed:
