ALIGNMENT PROCEDURES
7-1. General
Under normal conditions, the test set will maintain
the factory alignment over a long period of time. It
is necessary to realign the test set if any component
except the batteries is changed. Alignment procedures
are given in paragraphs 7-2 through 7-4.
7-2. Alignment of Meter Zero
a Set the polarity switch to OFF.
b. Adjust the meter zero adjustment screw located
directly below the base of the pointer for a 0 meter
indication.
a. Test Equipment Required. The only test equip-
ment required is a 100-ohm, 1 percent, -watt
resistor, FSN.
b. Procedure.
(1) Disconnect the unit from the case by remov-
ing the four front panel screws.
(2) Set the polarity switch to FWD PNP.
(3) Set the. function switch to OHMS E-B.
(4) Adjust resistor Rll (fig. 7-1) so that the
meter pointer indicates full scale on the OHMS scale.
