Voltage Terminals - Arbiter Systems 928A User Manual

Voltage Terminals

Two sets of voltage terminals allow you to apply volt-
ages up to 660 Vrms, max. They may also be scaled for
reading the primary voltage on a PT or transformer.
These inputs are labeled "CHANNEL A" and "CHAN-
NEL B."
Normally, a direct connection (e.g. 1:1) is the de-
fault selection for measuring voltages, however, you
can configure almost any voltage ratio for PT mea-
surement at the secondary. To configure voltage ra-
tios other than 1:1, see Configuring Channels A and B
starting on page 23.
Press 2nd AV to measure voltage at Channel A.
Press 2nd BV to measure voltage at Channel B.
Note: Voltage inputs are isolated by 1.2 Megohms
to each other and have a maximum input rating of 660
Vrms.
Caution - Max Voltage Input Level: Never
apply any signal to Channel A or B voltage input ter-
minals which is greater than 660 Vrms.
