the AC adapter must be connected for 4 hours in
order to fully restore the charge. If you need a
replacement AC/DC Battery Charger for the 630A,
contact the AMPTEC customer service department
and request an option “630DC” Battery Charger.

Setup and Use
Once the AMPTEC 630ES has had it’s batteries
charged for 12 to 24 hours it is ready for use. The
630ES consumes little power and generates virtually
no heat. Consequently, it may be used in any area
where the environment does not exceed the
specifications of Table B-2.
Avoid exposing the 630ES Explosive Safety Igniter
Tester to extremes of temperature which will affect
accuracy and shorten battery life-span.
630ES Explosive Safety Igniter Tester keyed
connector. In this way the user may not ever be able
to connect any test leads while the unit is charging.
The 630ES is designed so it is virtually impossible to
be powered (in operating - measurement mode)
directly from the AC line adapter. As an additional
note, the 630ES main power switch
must also be
in
the “
Off/Charging
”
mode
in order for the connected
battery charger to recharge the 630ES’s batteries.
For customers using 220VAC 50 HZ AC line power
for running the battery charger, please inform
AMPTEC’s sales department at the time of your
order and the appropriate adaptor will be included
with the 630ES Failsafe Ohmmeter shipment for an
additional fee.
A fully charged battery pack may power the 630ES
for approximately 8 to 10 hours before requiring a
recharge. Amptec installs a quality set of 4 each
Heavy Duty (5700 mAHr) Ni-Cad batteries. The
620A will also operate on a 4000 mAhr D cell Ni-
Cads with a shortened operating time between
charges.
The “Power” switch has two separate modes. The
“ON” position supplies internal battery isolated
power to operate the 630ES when they are charged.
If you turn on the 630ES, and the display does not
come on, it may indicate the batteries need charging.
The “OFF/CHARGING” power switch position is for
use when the batteries need charging or the 630ES is
not in use. As mentioned earlier of course the AC/DC
Battery Charger must be plugged into the 630ES’s
keyed connector to facilitate charging the batteries.
Although the batteries are fully charged prior to
shipment, it may be desirable to refresh the charge
for 24 hours before use. As a rule of thumb, the
630ES requires twice as much time to fully recharge
as the amount of discharge time. For example, if the
instrument was used continuously for 2 hours,
