The AC voltage This section describes how to configure AC voltage measurement from the front panel. Select the default delay to give the correct first reading for most measurements. For the most accurate measurements, the input that prevents the RC time constant must be stabilized to 1/50 of the AC signal level. Signals greater than 300 V (RMS) will cause self-heating of the signal regulator.These errors are included in the instrument specification. Changes in internal temperature due to self-heating may cause additional errors in other functions or ranges. The extra error usually disappears within a few minutes. Step 1: Configure the test leads, as shown below. Step 2:
Press [ACV] on the front panel. Step 3: Press Range to choose a range for measurement. Auto (auto range adjustment) selects range for measurement based on input. Compared with 28
