RM-111 Operations Manual
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 test –
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 D.U.T.
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-KYZ or RR-KYZ) test. Select Pulse Sensor. Select BNC if using an RM-KYZ, or
select Lemo if using an RR-KYZ.
9. If not already completed, follow the prompts on the RM-111 to make the appropriate
connections. See Figure 11.0 “Testing an Induction or Solid State Meter via KYZ Output” for the
applicable wiring diagram. The number of reference standards defi ned in the test setup determine
how the ports are confi gured. If using the RM-KYZ, connect it to port A. If using the RR-KYZ,
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 KYZ sensor is properly
connected, the LCD will show fl ashing segments that are synchronous with the KYZ output. Press
ENTER when alignment is achieved.
12. In this mode, the RM-111 counts the number of pulses from both the reference standard(s) and
the KYZ signal from the meter under test.While the test is in progress, the RM-111 display shows
the meter registration as it accrues and also shows the standards counting. When using a pulse
sensor, the test automatically stops when the pulse sensor senses the last pulse.
13. The test is now complete. To process the results press ENTER.
