620LK Operation and Maintenance Manual – Rev. J – Updated January 2020
SECTION A: RECEIVING AND INITIAL INSPECTION
A-1 Introduction to AMPTEC 620LK Bonding Milliohmmeter
Originally designed at the request of Lockheed Martin's engineering team, the AMPTEC
620LK Bonding Milliohmmeter has become the standard in its industry, being used in
aircraft hangars across the globe. The 620LK meter provides extremely safe and
reliable resistance testing on explosive or volatile devices at all times. Our various
safety board approvals (found in section F on page 18) demonstrate our dedication to
making quality products that are safe to use in a variety of atmospheres and
environments.
The AMPTEC 620LK Bonding Milliohmmeter is UL-913 approved as an intrinsically safe
apparatus for use in Class 1, Division 1, Groups A, B, C, and D locations for ambient
temperatures from -20° C to 50° C (T3 zones). The AMPTEC 620LK meter is also MIL.
STD. 810 MTD. 511 approved for use in explosive and volatile atmospheres.
Devices/processes that the 620LK meter can be used for include, but are not limited to:
Electrical chassis ground connections and continuity determination(s) on
electrical subsystems used in general purpose aircraft, helicopters, fighter jets,
UAVs, drones, missiles, etc.
Continuity determinations on fuses, electrical cable connections, heavy duty
metal to metal connections
Bonding measurements for metal to metal connections
Featuring an all metal case with a separate F.O.D. resistant battery compartment, the
AMPTEC 620LK meter has been specifically designed to keep ease of use and
reliability in mind. When it comes to safety, the 620LK meter has failsafe output circuitry
pioneered by AMPTEC to ensure that test current levels do not exceed the specified
failsafe current, even in worst-case component failure situations.
We're extremely proud of the engineering and quality that goes into each and every one
of our products we've created over the past 20 years. We hope you enjoy working with
our 620LK meter and encourage you to contact us if you have any questions or
comments. Thank you for your business!
A-2 Unpacking and Inspection
Should the box you receive your product in be damaged upon its arrival, notify AMPTEC
and the shipping carrier immediately. If your 620LK meter appears damaged, the
carrier's agent should authorize repairs before the unit is returned to our facility.
If the unit fails to operate or meet performance specifications (listed in section B on
page 5) notify the carrier's agent and AMPTEC immediately. Retain the shipping
container for the carrier's inspection.
Do not, under any circumstance, return equipment to any of AMPTEC's facilities or
sales offices without first obtaining an RMA number (see section E-2 on page 13) from
