5.2.9 Voltage TRMS
It is a simple function that continuously measures the voltage across the IEC cord
connector.
Test circuit for voltage measurement

Voltage TRMS procedure
Select the VOLTAGE TRMS function.
Connect the IEC cable to the instrument and into the normal mains supply as
shown on figure 5.23.
Store the result by pressing MEM key (optional).

Note:
One of the safety features incorporated into the GammaGT is that the voltage
measurement will start automatically from any mode when a voltage higher than
approximately 50 V (AC or DC) is applied to the IEC connector! If the voltage test
has not been preselected then the voltage cannot be stored, but all measurements
were prohibited until the voltage is removed.
