Preliminary Adjustments

Fully seat the test leads in the correct input jacks. If necessary,
using a small fl at tip screwdriver, slowly turn the mechanical
zero adjustment screw clockwise or counter-clockwise until
the needle indicator is directly over the three black zeros at
the left end of the scale.
Check Condition of Internal Battery
Before making resistance or continuity tests, check the
condition of the internal battery. First turn the function/range
switch to the ohms Rx1 position. Short the test leads together
and the needle indicator should defl ect to the right side of the
scale. Keep the test leads shorted together while simultane-
ously turning the zero ohms adjustment dial until the needle
indicates zero at the right side of the ohms scale. If the needle
will not zero, replace the batteries with two new 1.5 volt AA
size batteries (see Battery Replacement).
