Functional Description
2.1 Introduction
The following paragraphs provide a brief functional description of some
Model 931A components. Figure 2.1 illustrates the front panel.
2.2 Inputs
2.2.1 Voltage
Measure AC or DC voltages through four color-coded insulated banana
jacks on the front panel.
Labeled A, B, C, and N, each terminal can
accept input voltages of up to 750 Vrms or 1000 Vdc. Each input voltage
terminal is isolated from signal common with an impedance of 1 megohm,
and is physically isolated from the chassis.
2.2.2 Current
The 931A features three independent, transformer-coupled AC current
inputs, accessible via three pairs of front-panel binding posts, which are
color-coded for polarity and labeled A, B, and C.
Each terminal can accept an AC signal with a rms current value of up
to 20 amps. All current inputs are isolated to withstand a potential of
1000 Vpeak from chassis ground.
