When the 620ES is first turned on, the unit
draws more internal power to heat up the unit’s
ovenized zener voltage reference. If the “Low
Battery” Indicator only comes on for a few (i.e
10 to 15 seconds) seconds when the 620ES is
first turned on then goes out, the battery levels
are starting to indicate the charge level is getting
low.

Setup and Use
The AMPTEC 620ES Igniter Tester may be
setup to operate within minute(s) of power "turn
on" (unless your in an extremely cold
temperature - allow more time for warm-up - 15
minutes). A quick check for no sign of the "low
battery indicator" and test lead integrity check
and it should be ready to use.
Once the AMPTEC 620ES has had it’s batteries
charged for 12 to 24 hours it is ready for use.
The 620ES 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 620ES to extremes of
temperature which will affect accuracy and
shorten battery life-span.
