2. Wrong relay duration.
3. Relay set for wrong activation
i.e.

.
1. Relay duration is set at a value other
than 00.00. This causes the counter
to auto-reset at the preset.

steps show the setup for units with
all of the available options. Options
not ordered will be suppressed in
the programming menu.
1. Recheck power wiring

install a surge suppressor.
1. Recheck input wiring.
2. Recheck scale factors and factor
calculations.
3. Replace transmitting device.
4. Recheck debounce filtering selection
"hi cps" or "lo cps".
5. To confirm set scale factor at one
and connect a wire to pin #7 and
touch it to pin # 5 (input A). Each
time pin #5 is touched counter A
should count once. If not, call
factory for RMA.
1. Check scaling factor, if it is correct,
lower the number of significant
figures.
2. Reprogram the unit and be sure to
enter a decimal (enter one and re
move it if a decimal is not desired).
1. Relay A (and B if Prewarn) will only
energize when start is activated.
2. Recheck programmed relay duration.
3. Recheck programmed relay
activation mode.
1. If Relay B output is not being used,
set the relay duration to 00.00.
