These AC Voltmeters are capable of measuring AC voltages of
10 Hz - 500 kHz. The response characteristics of the
pointers are of mean-value response.
The scales are calibrated with root-mean—square values for
sinusoidal waveform inputs.. Range selection of the
Dual-pointer Voltmeters (Models AVM23
AVM25R) can be made with, the two channels directly linked
together or with the two channels linked together providing
a certain differential level between them, as well as it can
be made independently for each of the two channels. Also»
these, models of voltmeters are incorporated with a GND MODE
selector so that the circuit ground can be connected to or
floated from the case ground.
Voltmeters are capable of remote
control of range selection.. The remote control signal used
for this purpose is a positive-logic TTL-level binary-coded
signal with 4 bits per channel. The Remote Controllers which
can be used for this purpose are RC01-AVM, RC02-AVM,
RCOl-ORC, and RC02-ORC, When the IF01-AVM (GP-IB interface)
is used, digital data corresponding to pointer deflection
can be sent to the CPU making use of the range selection
control signal and DC output signal of the voltmeter.
All of the six models of Voltmeters are provided with an AC
output terminal which delivers an output signal of
approximately CL.1 V rms for full scale. Models AVM23R
Voltmeters are provided with a DC output terminal
which delivers an output signal of 1 V (±3%) for full scale..
