4 Operation
The A 1322 / A 1422 operates in conjunction with the master instrument (PAT or
Machine tester).
Following is the list of applicable testers; in this manual they are referred as a master
instrument:
MI 3310 SigmaPAT (SigmaGT) and
MI3321 MultiservicerXA.
4.1 Connections
Required and optional connections between A 1322 / A 1422 and the master instrument
are shown in the following figure.

Connection of MI3321
instrument
Required connections are:
-
Measuring connection between PAT test socket (5) on A 1322 / A 1422 and
mains test socket of the master instrument, and
-
RS232 communication interface between the A 1322 / A 1422 (7) and PC/Printer
connector on the master instrument.
Optional connections:
-
when measuring prolongation cords and PRCDs via test sockets 13,15,17 the
EB(6) should be connected to the EB/S (or S/C1) terminal on the master
instrument . The connection is used for earth bond and polarity tests.
The EB(6) connection is not intended for measuring earth bond of appliances not
connected to sockets 13,15,17, touch current, insulation resistance S, substitute
leakage current S). For this tests the EB/S (or S/C1) terminal on the master
instrument shall be used (no connection to the EB(6) socket on the A 1322 /
A1422).
-
The master instrument can be optionally supplied via power supply socket (1). It
is recommended to use this connection, especially if no external 230 V wall
sockets is available. The voltage on supply socket (11) is turned on/off with the
fuse/circuit breaker (2) on A 1322 / A 1422.
