A-1. Introduction to the AMPTEC 601ES
Explosive Safety DMM / Igniter Tester
Power On
The AMPTEC 620A, 630 , 640 series and now
the AMPTEC 601 Series Explosive Safety
DMMs are designed to be the "
",
and provide extremely safe and reliable voltage ,
current and resistance measurement/testing of
explosive or volatile devices. Safety Approvals
from various Safety Boards include, the U.S. Air
Force ( 620A-4) for generic use on missile
warheads and the US NAVAL ORDNANCE
CENTER (630AN 630BN, 640N and other
versions pending). Some of the devices the
601ES DMM Explosive Safety Meter may be
used on include: fuses, squibs, igniters, EBW,
explosive bolts, rocket motor squibs, to name a
few.
The AMPTEC 601ES Explosive Safety DMM
supports safe ordnance testing. Many customers
need to safely measure stray voltage circuitry (
RMS AC and DC), stray current and resistance
using the failsafe output circuitry proprietary to
AMPTEC RESEARCH insure that test current
levels coming from the 601ES don’t exceed the
specified "failsafe current" even in a worst-case
component failure situation. The failsafe feature
is tested in every instrument before shipment. A
built-in passive (analog) DC Milliammeter also
lets the user verify actual 601ES DMM current
output levels prior to connection to any EBW,
squib or detonator.
- The AMPTEC 601ES DMM
Explosive Safety Meter main "Power" switch
to turn the
meter "ON" or "OFF". This feature helps
prevent the unwanted effect of bumping of the
power switch and accidentally turning the meter
"OFF" or "ON".
Low or Dead batteries ( AA type Alkaline - 4
each ) is the primary reason for the AMPTEC
601ES DMM not powering up. If the batteries
reach a low energy level the unit's LCD Display
"LO BAT" indicator appears on the display.

must be held down for 2 seconds
The AMPTEC 601ES DMM Safety
Meter has a
circuit that indicates when it is time
To replace the batteries. They can be replaced
without effecting the calibration of the meter.
The batteries are housed in their own
compartment completely separate from any
active electronic circuitry.
Should the AMPTEC shipping box appear
damaged upon arrival, request that the carrier's
agent (i.e. UPS) be present when the unit is
unpacked. If the 601ES DMM Explosive Safety
Meter appears damaged, the carrier's agent
should authorize repairs before the unit is
returned to the factory. Even if the instrument
appears undamaged, it may have suffered
internal damage in transit that may not be
evident until the unit is operated or tested to
verify conformance with its specifications. You
may refer to the
(i.e Test leads etc.)
If the unit fails to operate or fails to
meet the performance specifications
of section B, notify the carrier's
agent and AMPTEC RESEARCH .
Retain the shipping carton for the
carrier's inspection.
or any of its sales offices
an (RMA) Return Material
Authorization number. We need to know who to
contact and how to contact (i.e. phone number
and FAX number) in order to properly
coordinate the return of the repaired AMPTEC
product.
We may
possibly be able to fix the problem over the
phone and prevent you from having to return the
unit to AMPTEC for repair.

Inspection
DO NOT return equipment to AMPTEC
RESEARCH
By calling AMPTEC RESEARCH
first, prior to just returning the 601ES DMM
Explosive Safety Meter, we can often trouble-
shoot (based on the symptoms you describe)
and identify the problem over the phone (i.e
battery loose in the battery holder).
