RM-111 Operations Manual
Demand – Enter the desired number of minutes for the demand test. To omit the demand test,
enter zero.
Pulses/Rev – Enter the number of pulses (or equivalent pulses) per revolution of the meter under
test. Use the calculations above and enter one pulse per Ke value.
Creep Mins – Enter the desired number of minutes to be used for the Creep test.
* The “
Test By:
” parameter input allows the user to select the type of tests –
Revs
or
Energy
.
if
Energy
is selected, the “
FL Revs:
”,”
PF Revs:
”, and “
LL Revs:
” parameter inputs dynamically
change to “
FL Wh:
”, “
PF Wh:
”, and “
LL Wh:
”.This allows a test to be stopped after a pre-set
amount of energy has been accumulated by the DUT
4. Press ENTER to exit the Test Setup screen.
5. From the Main Menu select RUN TESTS.
6. Select Test Meter.
7. Select the previously confi gured test setup.
8. The RM-111 will prompt the user to select either a Manual (RM-1S or RR-1S) test or a Pulse
Sensor (RM-DS, RR-DS, RM-1H, or RR-1H) test. Select Pulse Sensor. Select BNC if using an
RM-1H or RM-DS, or select Lemo if using an RR-1H or RR-DS.
9. If not already completed, follow the prompts on the RM-111 to make the appropriate
connections. See Figure 14.0 “True Three Phase Meter Testing (Using Customer Load)” for the
applicable wiring diagram. The number of reference standards defi ned in the test setup determine
how the ports are confi gured. In this application, three standards are used. If using the RM-1H
or RM-DS, connect it to port A. If using the RR-1H or RR-DS, connect it to the PICKUP input.
Connect the standards to ports B, C, and D.
10. Once connections are complete, press ENTER to start the test.
11. The RM-111 starts the ALIGN PULSE SENSOR TEST to allow for the pulse sensor to be
checked. During this time, the disk rotates at full load current. When the 1H or DS sensor is
properly connected, the LCD will show fl ashing segments that are synchronous with the sensor
output. Press ENTER when alignment is achieved.
