Avoid exposing the 601ES Explosive Safety
DMM to extremes of temperature which will
affect accuracy and shorten battery pack
lifespan.
Once the 601ES DMM main power switch is
turned "ON" and following a (1) minute
warmup, (
) the AMPTEC 601ES
Explosive Safety DMM should be ready for
general purpose testing and use.
The 601ES DMM operator may be asked to
perform a series of tests (i.e. verify the test
current is less than 10mA with the unit's DC
milliammeter) prior to connection to any
explosive device under test.
Test lead sets may also be placed in the pouch
which holds the laminated AMPTEC 601ES
DMM Operator Instruction Card.
provided there is No ‘LO BAT’
Indicator shown
To replace low batteries first unscrew the
battery compartment lid and lift. Remove the
battery holder, plastic tie and low batteries.
Replace with a new set of (4) “AA” batteries
according to polarity. Using the spare plastic tie
included in the battery compartment, wrap the
plastic around the battery holder and secure.
Cut excess plastic. Next, wrap the black and
red wire around the battery holder and place the
holder into the compartment. Lastly replace lid
and screw in screws to secure. See Fig. A-4
above. *Please note: After replacing battery
holder with (4) new ‘AA’ batteries; secure with
a new plastic tie lock.
The 601ES Explosive Safety DMM 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-1.

Sect. A - Receiving and Initial Inspection
The AMPTEC 601ES DMM comes factory set with
an “Auto Turn-Off” time out of 30 minutes.
With certain batteries at the end of their power
capacity the “LO BAT” display may be only on for a
minute or less before the 601ES Automatically shuts
down. As an example, if you turn it on and don't see
“LO BAT”. Then in a few minutes walk out on and
return to discover the meter is turned off,
are the primary reason for this. Any time
the “LO BAT” display stays on for more than a
second or two it is time to exchange the batteries.
