RM-111 Operations Manual
Time* – not applicable for this test
Test by* - Select PULSE
Type – Select D. Gating (display gating) for the gating method
#Standards – Enter the number of reference standards that will be used
Mode – If more than one reference standard is used, the user must choose between single-phase or
polyphase modes of operation.
Ref Type – This defi nes the reference standard output pull-up value. Select Radian (150 ohm).
Other is 1000 ohm.
Input A** – Select either DUT or REF
SER#1 – Enter a serial number for standard 1, if applicable.
SER#2 – Enter a serial number for standard 2, if applicable.
SER#3 – Enter a serial number for standard 3, if applicable.
* The “Test By:” parameter input allows the user to select the type of test – TIME, PULSE,
MANUAL, or ENERGY. If ENERGY is selected, the “ Time:” parameter input dynamically
changed to “Energy:”. This allows a test to be stopped after a pre-set amount of energy has been
accumulated by the D.U.T.
**When testing a standard by counting output pulses, the RM-111 will count the output pulses of both
the reference standard (REF) and the standard under test (DUT), until the selected number of pulses
are achieved. The “Input A:” parameter input allows the user to select either “REF” or “DUT”. If
“REF” is selected, the test will stop after the RM-111 counts the specifi ed number of pulses from
the reference standard. If “DUT” is selected, the test will stop after the RM-111 counts the specifi ed
number of pulses from the standard under test. To reduce errors associated with testing standards
with different pulse output constants, the “Input A:” parameter should be set to “DUT” whenever
the DUT has a lower pulse resolution than the reference standard. If “DUT” is selected, the DUT
must be connected to PORT A. Follow the prompts on the RM-111 for connection details.
