Arbiter Systems 928A User Manual page 41

rectly read the primary value. The example below
shows how to configure a specific probe.
CAUTION: No Direct Current Input – connect CT
probe only. See caution for CT probe use on page 4.
EXAMPLE: Current Probe Specification
AC Current Probe
AC Input: 75 Arms, maximum
AC Output: 10 mV/A rms
660 Vrms Working volts, max.
This probe produces 10 mV at the output terminals
(to the 928A) for an input current of 1 Amp.
MAXIMUM OUTPUT VOLTAGE
= AC Input
= 75 A 10 mV/A
= 750 mV (or 0.75 Vrms)
It is safe to apply a current or voltage to either
current input if it is less than or equal to the specified
maximum of 1.2 Vrms, or 1.2 Arms. In this case it is
safe to apply 0.75 Vrms being less than 1.2 Vrms. If
using a current output CT, you would be able to apply
up to 1.2 Arms to either current input.
Selecting a Channel Function
