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 TV 465 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.
