Relay 1, KYZ-Rated Contacts
Relay 1 is a set of solid state contacts useful for keeping track of energy
using the KYZ method. To set up these contacts, refer to Figure 7.16.
1. Select SETUP (key) > 7 - Trigger Setup > RELAY SETTINGS (soft

2. Specify the channel (A, B, C or Total), the type of signal (e.g. Watt-
hour), and the scale (see below under Kp Register Scale Factor).
Kp Register Scale Factors
Correct scaling is necessary for accurate KYZ pulse metering. Enter in
the value using the numerical keys on the front of the Model 933A keypad.
