Testing Methods and Tools
To Adjust Gain Settings
Use the gain adjustment setting to adjust, or zero-out, any error a test standard
measures. Use the WGAIN and VARGAIN to adjust Watts and VARs. For a
full description of this feature, see Gain Adjustment on page 12.11.
Step 1. Use the DOWN ARROW pushbutton to select Gain Settings on the
front panel display.
Step 2. Press ENT.
Step 3. Use the UP ARROW and DOWN ARROW pushbuttons to select
WGAIN
or
VARGAIN.
Step 4. Press ENT.
Step 5. Use the RIGHT ARROW and LEFT ARROW pushbuttons to select the

front-panel display.
Step 2. Press ENT.
Step 3. Use the UP ARROW and DOWN ARROW pushbuttons to select the

To Use the Optical Test Pulse
The optical test pulse is an energy pulse output that repeats at a predefined
consumption rate. This optical pulse operates similarly to KYZ pulses, except
that the optical pulse operates with rising edge pickups (see KYZ Outputs on
page 8.13). The register currently displayed on the front panel determines the
test pulse quantity. Select from among the following quantities:
➤ Watt-hours
➤ VAR-hours
➤ VA-hours
Select any direction (in/out, per quadrant) and phase (A, B, C, or 3) register
for optical port output. The pulse weight (KET) setting for each pulse is set to
a default value of 1.8 unit-hours per pulse. This results in the values shown in
Table 12.2.
