INSTALL THE FOLLOWING PARTS

Install the double battery contact as shown in Figure 5.

Install the two single battery contacts as shown in Figure 5. Solder the bare wires from B1 to the battery

contacts (as shown in Figure 5).

Install the the two AA batteries in the battery compartment. Be sure to observe the polarity markings on

the bottom of the battery compartment.

Connect the battery snap to the 9 volt

battery and place the battery in the 9 volt

battery compartment.

Place the thumb wheel knob onto the 0

Ω

ADJ pot located at the lower right of the

meter dial.

Install the back cover using the 5/8

screw as shown in Figure 6.
