4. OPERATION
NOTE: All models display an 8 in all digits for
1 sec. at power-up.
700 Hour Meter (AC/DC)
To Display & Operate: Apply DC+ or AC hot to pin 1
and DC – or AC neutral to pin 2. The accumulation of
elapsed time is indicated by the flashing hourglass icon.
If power has been applied for 5 seconds minimum, the
accumulated time will be stored in non-volatile memory
when power is removed.
To Reset: (for Resettable Models) Apply DC+ or AC hot
to pin 4 for 1/2 second minimum while power (pins 1 &
2) is applied for 5 seconds minimum. The reset voltage
must be at the same level as the voltage used to power
the unit.
701 Hour Meter (AC/DC or DC Only)
To Display: Apply DC+ or AC hot to pin 1 and DC– or
AC neutral to pin 2. The display is activated at this point
but the elapsed time will not be accumulated until a
signal is applied to pin 3. Note, for proper operation:
Power must be applied to pins 1 & 2 before or coincident
with pin 3.
701 Hour Meter continued
To Operate: Apply DC+ or AC hot to pin 3 for 1/2
second minimum (AC/DC model) or DC+ for 1
millisecond mimimum (DC Only model). The accumulation
of elapsed time is indicated by the flashing hourglass
icon. If power (pins 1 & 2) has been applied for 5 seconds
minimum, the accumulated time will be stored in non-
volatile memory when power is removed.
To Reset: (for Resettable Models) Apply DC+ or AC hot to
pin 4 for 1/2 second minimum while power (pins 1 & 2) is
applied for 5 seconds minimum. The reset voltage must be
at the same level as the voltage used to power the unit.
703 Counter (AC/DC or DC Only)
To Display: Apply DC+ or AC hot to pin 1 and DC – or AC
neutral to pin 2. The display is activated at this point but
the count will not be started until a signal is applied to pin
3. Note, for proper operation: Power must be applied to
pins 1 & 2 before or coincident with pin 3.
To Operate: Apply DC+ or AC hot to pin 3. The count is
incremented when the input signal is removed from pin 3.

16 17
703 Counter continued
The input signal must be applied for 1/2 second
minimum (AC/DC model) or for 1 millisecond
mimimum (DC Only model). If power (pins 1 & 2) has
been applied for 5 seconds minimum, the incremented
count will be stored in non-volatile memory when power
is removed.
To Reset: (for Resettable Models) Apply DC+ or AC hot to
pin 4 for 1/2 second minimum while power (pins 1 & 2) is
applied for 5 seconds minimum. The reset voltage must
be at the same level as the voltage used to power the unit.
732 Hour Meter (DC Only)
To Activate Display: Apply DC+ to pin 1 and DC- to pin 2.
To Activate LED: Apply DC+ (for active-high models) or
DC- (for active-low models) to pin 3 during indicator-on
condition.
To Activate Elapsed Time: For models without separate
enable option - elapsed time is activated when power is
applied to pins 1 & 2. For models with enable option -
apply signal to pin 4. Note: Power (to pins 1 & 2) must be
applied before or at the same time as signal to pin 4.
732 Hour Meter continued
Operation: Apply DC+ to pin 4 for 1 millisecond
minimum. Activation (accumulation) of elapsed
time is indicated by the hourglass icon flashing. Time
accumulated will be stored into non-volatile memory when
power is removed, if power (to pins 1 & 2) has been applied
for the minimum of 5 seconds.
Reset: (for resettable models), Apply DC+ to pin 4 for 1/2
second minimum, while power to pins 1 & 2 has been
applied for 5 seconds minimum. Note: The reset voltage
must be at the same level as the voltage used to power
the unit.

5. TROUBLESHOOTING
To maximize the life of this meter, please read
all instructions carefully and review Safety
Precautions on inside front cover of this manual. Most
minor problems can be resolved by removing all power
for at least 10 seconds and then reconnecting.
Problem Possible Cause
No Display Power not connected or too low.
Display Present, but counter
does not activate.
Input (or enable) wire not connected. Start
Input not connected. Input voltage not reaching
specified minimum signal level.
LED not turning ON during
activation condition. Switch or switch-connection faulty.
