The Real-Time Values screen shows current readings to verify that the system is
configured properly. The tables display the real-time values of Volts, Amps, Kw, KVA,
KVAR, and Power Factor (PF) for Phase L1, Phase L2, and Phase L3. This screen
also displays the CT type connected to the MD-P1 or MD-P1D Power Meter and the
CT value.
Values displayed for Volts, Amps, Kw, and so on should make sense; in other words,
the values in the table should be relevant for the service being measured. This
indicates the MD-P1 or MD-P1D Power Meter setup is correct. It may also be useful to
use a handheld amp meter to test the current and compare its readings to the values
provided on the
Real-Time Values screen.
To acquire new measurement values, click Update to retrieve a new set of values for
the MD-P1 or MD-P1D Power Meter. For Auto-Update, select the check box to
automatically update values approximately every 20 seconds.
Using the Optional Visual Display to Verify Real-Time
Values (MD-P1D Model Only)
The MD-P1D Power Meter has a two line × 16-character backlit visual display that
enables you to read real-time values directly from the meter. It has two rows of 16
characters that auto cycle between informational screens every two to three seconds,
with real-time values updated every second. Click the
Hold button (located on the side
of the meter) to stop the cycle until it is clicked again, or until a set timeout is reached.
Some information such as protocol, CT type, Volts, Aps, Kw, PF and so on, is
displayed during each cycle. See
Appendix E for complete cycle information.
