Select the desired Start Option i.e.,
N. OPEN
(Normally Open). Select the desire
Start Latch,
ON
(Normally ON). If it is desired to use the reversal of the Start
signal to stop the timer (such as timing the closing and opening of a single
contact, when measuring the trip-free operating time of a circuit breaker) switch
the Start Latch OFF.
3.
When it is desired to use a separate stop gate signal to stop the timer, select the
required Stop Option i.e.,
N. OPEN
(Normally Open). Set the Stop Latch to the
desired setting. For example, if it is desired to have the timer stop upon the first
stop signal only (ignore contact bounce), set the Stop Latch to
ON
.

Make test connections to the
TIMER START
and
STOP
Terminals. When AC or
DC voltage is applied, CATII insulated test leads are required (use PN684000
and 684001 leads).
5.
When the appropriate start and stop signals are applied, the timer will indicate the
trip time in both seconds and cycles. Note that the time base is also displayed (
60 HZ
or
50 HZ
) to remind the user what the time base is when timing in Cycles.
