The AC/DC outputs on the HVM100 are independent and
simultaneous for all three channels. First we will discuss the

AC/DC outputs.

AC output is useful for frequency analysis by an external
analyzer or for recording in a tape recorder. The DC output
is useful for a chart recorder, or to measure the voltage pro-
portional to the RMS or peak value.
The DC output is updated according to the averaging time. If
the averaging time is set to slow, the signal on the DC output
pin for the selected channel will be updated once per second.
If the averaging time is set to 60 seconds, the signal on the
DC output pin for the selected channel will be updated once
every 60 seconds.
The AC/DC output connector is a 5 pin switchcraft connec-
tor located on the bottom edge of the instrument. The pinout
is as follows:
Example:
Chart recorder output, monitoring the
DC output, with an averaging time of 60 seconds.
