To program the Test Pulse LED, from the Device Profile menu in Communicator EXT, first click
on KYZ Outputs, then click on any of the Test LED pull-down menus to configure the following
settings:
1. Assigned Channel - choose from settings.
2. Watthour per Pulse - enter the value in the secondary.
3. Pulse Width - can be set from 5ms to 635ms.
4. Mode - can be enabled or disabled.
5. Form - can be selected between Form A and Form C.
Click OK. Then click Update Device to send the new settings to the meter.
The unit for the calibration pulses is Watthours. The initial value of each pulse (Kt) is 1.800
secondary Watthours per pulse.
4.1.2: LCD Display
In Test Mode, the LCD display provides user access to accumulated real, reactive and apparent
energy as well as block demand for real power. There are eight screens in Test Mode: Wh - Del,
Wh - Rec, VARh - Q1 & Q2, VARh - Q3 & Q4, VAh - Q1 & Q4, VAh - Q2 & Q3, Watt Demand
Test Rolling and Watt Demand Test Block. See section 4.2.2 for more detail.
The LCD display also includes three phase voltage annunciators. These annunciators are labeled A,
B and C to indicate the presence of voltage on the indicated phase. If voltage is not present on one
phase, its indicator will not be displayed. These indicators also show whether current is flowing on
the indicated phase. If no current is flowing on a phase, the annunciator will blink. When current is
flowing, it will show a continuously illuminated digit. This annunciator indicates phase sequence.
4.2: Test Mode
Test Mode allows the meter to be tested without disturbing billing data or setting a new
maximum demand. Test Mode performs the same function as setting the pointers back on an
electromechanical meter after testing.
While operating in Test Mode, the meter uses the same measurement and calculation processes that
are used in Normal Mode. The only difference is that the billing numbers stored in the meter are not
updated with the real-time reading. This preserves the billing numbers while testing is performed.
4.2.1: Entering Test Mode
To enter Test Mode, you must pass the meter's security system. In most instances, this requires you
to remove power from the meter, break the meter seal and remove the Lexan cover, and then
repower the meter.
