Timing Status
The Timers section contains three Timing Status lights that function for
any and all timers:
Reset Active timers are reset to 0.00.
Running Time test is in progress.
Stopped Relay has responded. Timer shows elapsed time in
milliseconds, seconds, or cycles.
When System Output is clicked, the enabled sources turn on and the
enabled timers start. If the timer Stop button is then clicked, these sources
are switched off and the System Output button returns to its previous
status.
Timer Controls
Click Stop to stop timers that have not stopped due to a pre-defined stop
condition. Click Reset to return all the active timers to 0.00.
If Stop is clicked while the timer is running, NO-OP appears in the field
for that timer. NO-OP means No Operation. It appears in the timer
readout after an unsuccessful or an interrupted test. For example, when a
timer is started and then stopped manually during a test, NO-OP appears
in the timer field because the relay under test did not respond.
Measurement Units
Set the measurement units for the timers with the radio buttons located
along the bottom of the Timers section. The options are milliseconds,
seconds, and cycles. The default selection is Seconds (Sec.).
To measure the elapsed time in milliseconds, click the radio button for
mSec. To measure the number of cycles that elapse during a test, click
the radio button for Cycles. For example, if the default system frequency
of 60 Hz is set, the timer shows 90 cycles for a time test that
lasts 1.5 seconds.
