3.3 Meter Mechanical Zero

3.3.1 Place the Test Set on its back on a flat, horizontal surface.

Set the Range Switch to the OFF position.

3.3.2 Examine the position of the Pointer on the Dial. If it is ex-

actly on the Zero Mark, then the meter is mechanically zeroed and

no adjustment is necessary.

3.3.3 If the Pointer is not exactly aligned with the Zero Mark,

then the mechanical zero of the meter needs adjustment. This is

done by using a small, flat blade screwdriver to adjust the Zero Ad-

just Screw. Slowly turn the Zero Adjust Screw clockwise until the

Pointer is approaching the Zero Mark from below zero. When the

Pointer is resting on the Zero Mark, reverse the Zero Adjust Screw

one eighth turn. This will disengage it and reduce the effect that

temperature, shock, and vibration will have on the mechanical zero

of the meter.
