Amptec Research 620A 4R, Руководство по эксплуатации и обслуживанию

Страница: 11 / 34

When the AMPTEC 620A4R is measuring 1.2345
Ohms the Option “620ISO” outputs 123.45 mV
DC. The operator can connect any system DVM
(i.e HP , Fluke etc,) with a
GPIB interface which
can be directly connected to a PC for automated
measurements.
Option 430 4000-ITS Mating Connector
AMPTEC offers an adapter connector that
provides equivalent circular socket con-nections
found on SIMPSON 4000 ITS
tm
, and Alinco 101
series Circuit Igniter Testers.
The diagram below shows that the backside of
the OP430 connector adapter has an acrylic tube
filled with an insulating casting resin. The
hardened tube provides additional mechanical
support while handling and connecting the
mating connector.
The Safety Board (U.S.A.F. Non-Nuclear
Munitions ) approved adapter (
OP430 ) has dual
banana leads which provide a 4 wire Kelvin
connection from the adapter to the 620A
Ohmmeter (No lead resistance errors).
In some
applications (i.e. AIM-7 Missile harnesses)
regular alligator clip leads cannot properly
connect to
( screw on ring collar type
connectors)
the small recessed electrical
sockets inside a connector harness
that
normally mates with the SIMPSON 4000ITS or
Alinco 101 series Igniter Tester(s). The OP430
Adapter mimics the older 4000ITS Ohmmeter
(pin into socket) connection. The “OP430” has
the AMPTEC 620A Ohmmeter act as a 2- wire
ohmmeter from the OP430 connector out to the
resistance under test, just as the 4000ITS
Ohmmeter or Alinco 101 series Igniter Testers
would perform.
