Introduction AMPTEC 630ES
The AMPTEC 630ES Explosive Safety
Igniter Tester was derived from the model
AMPTEC 620A-4 Igniter Tester (The
USAF Squib Meter"). The AMPTEC 630ES
Explosive Safety Igniter Tester's features
were originally developed for the United
States Depart. of Energy at Los Alamos
National Laboratories. It is used to check
high explosives and related EEDs
(electro-explosive devices) circa 1999. Its
has numerous safe operation features and
Safety Board Approvals (contact
AMPTEC RESARCH Sales Dept.) that
have reviewed the unit’s failsafe circuitry
and deemed it as the “HE meter” (high
explosive meter) for use by Los Alamos
National Laboratories, NASA and US Air
Force Range Safety .
User Note: When key is removed from the AMPTEC 630ES, the
unit's circuitry is not connected to any test lead connection that
may be going off to some "squib" under test. If the user puts the
key in their pocket, they know that nothing the 630ES does can
electrically effect the "squib" wires that they may be going to
connect to. Upon return to the 630ES, only when the key is
inserted and the keyswitch is in "measure mode" is the failsafe
ohmmeter Igniter Tester connected to the test leads (if plugged
into the "Connections" port.
630ES Key Switch
In the locked “SAFE” mode all test lead inputs are shorted
together and completely disconnected from all 630ES
electronics. In “Measure” mode the J1 lines -Ihigh is “ON”
for 630ES I high, J1 Vhigh is “ON” for 630ES V high, J1 V low
is “On” for 630ES Vlow, and J1 Ilow is “ON” for 630ES Ilow

Getting started – If the AMPTEC 630ES is new to you, the lid of the 630ES contains a laminated instruction
card that diagrams all of the AMPTEC 630ES switches, connections, milliammeter use and more . . (see near
the last slide of this presentation for the 630ES User Reference Instruction Card diagram.

Startup Check Out Procedure
630ES
630ES-504
The first item to examine is to check the
calibration sticker's due date for the
AMPTEC 630ES Igniter Tester. If the due
date is still valid and not expired, it is ready
to begin the safety check procedure. If the
calibration due date is expired then contact
your calibration laboratory or AMPTEC
RESEARCH. A tamper resistant calibration
sticker is usually located around the
perimeter screw(s) area to the AMPTEC
630ES Igniter Tester DMM top plate. The
sticker will most likely be covering one of
unit's the calibration access screws.
Step 2: Procedure for turning "ON" the AMPTEC 630ES Igniter Tester :
Using the unit's main operating power switch located in the lower left portion of
the front panel, flip the toggle bat of the power switch (grey silicone rubber boot
protected) into the “UP” or “ON” position .
After the AMPTEC 630ES is powered up you should see the red LED display
come on. A low battery level is indicated with a negative or minus sign in the front
of the unit's L.E.D display. Adequate battery level – the minus sign may initially
come on for a couple of seconds but should go out and not be continuously lit. In
order to charge the 630ES, the meter must be turned off and the battery charger
(AC powered) plugged into the unit’s “CONNECTIONS” port. Do not operate
the 630ES with a “Low Battery” indication as the readings can be inaccurate.

The 2.0 ohm range on the AMPTEC 630ES Igniter Tester should be
checked out first. After pressing the 2 ohm range (momentary) switch,
the range indicator LED should come on.
This indicates the 2 ohm range is selected .
2.0 Ohm Range - Checkout / Verify Procedure
5 mA
There is positive (+) and negative (-) polarity
associated with the AMPTEC 630ES Test Leads.
AMPTEC 630ES Test Lead polarity doesn’t effect
Red / High
the resistance measurement, but it (polarity) does
banana lead
effect the use of the milliammeter. The banana jack
lead with the red indicator is Voltage and Current
HIGH, while the banana jack with the black
indicator is Voltage and Current Low. When using
the built-in analog DC milliammeter (red jack on the
meter +, and black jack on the common black jack)
proper test lead polarity connection must be
maintained to facilitate proper operation of the
milliammeter. In addition the 630ES key must be in
the keyswitch and the switch in “measure” mode in
order to measure anything with the 630ES Test
Leads. The milliammeter should indicate the units
test current level is less than 5 mA, which is viewed To "CONNECTIONS" port
as just right of the the 12 O'clock or mid scale needle
position.

The key must be in and switched
to the measure position in order to
make any measurement. In the
"SAFE" mode the connection port
leads are shorted (No output for
Safety purposes)

2.0 Ohm Range Check
1. Next check the 2 ohm range by plugging
in the red banana jack lead into the 0.100
(1/10th) Ohm reference resistor. Note: this resistor
is only approx. 0.100 ohms . The 630ES reading
will be approx. 0.10 ohms (i.e .0995 ohms
or 0.1011 ohms.

The purpose of having a reference resistor
is only to verify the 630ES is measuring in the
proper magnitude or level of resistance.
To "CONNECTIONS" port
The unit's reference resistors are not be
0.100 ohm resistor
considered as a calibration standard, but
only as a simple measurement verification or
checkout tool.
If the 0.100 ohm check looks OK, try plugging
the red banana jack lead into the 1.0 ohm reference
resistor. Again the 630ES should display a reading
of approx. 1.0 ohm (i.e .9985 ohms or 1.0012 ohms etc.)
