The next interval will start at 11:10am, and so on. This is used to precisely time the demand
intervals for comparison to meter data acquisition systems.
Synchronize To Meter
If the user would like to compare accumulated results from the PowerMaster
®
and the meter,
enter the Demand Test screen as normal. To synchronize both the meter and the PowerMaster
®
,
do the following: press the RESET on the meter to reset all accumulated demand results and
press the F1 (Restart) button then F6 (Start Testing) on the PowerMaster
®
SIMULTANEOUSLY.
This will synchronize the results and accumulate power accordingly. After the test is complete,
compare the “Demand Interval” results against the meter. These results are the accumulated
power during the demand period.

Customer Load Trending Data
Functionality:
Moves to the next page to display VA, VAR, and PF trend graphs
Goes back to the test results
Description:
This screen displays the data that is accumulated during the test period. When performing
customer load meter tests, the customer’s load is normally changing. These graphs give the user
a visual perspective of how much the load changed during the test. If the graphs appear to be
excessively changing, the user may decide to do a retest when the load is more stable. Also,
viewing these graphs gives the user the ability to troubleshoot problems that cannot be
immediately seen. For example, if there is a loose connection at the test block for voltages, the
graph will display the “peaks” and “valleys” to show the intermittent connections during the meter
test (however minuscule in detail).
