HOW TO INSTALL

FUSE AND BATTERY

Unscrewbaseofohmmeterbattery/fuse attachment

insert fuse (Use Litte/fuse type 8AG - 360x023

1AMPfast blow) and AAAbattery (Cal No 912, not

supplied) into probe end as shown in figure.

Screw base on to probe.

NOTE: If you fail to get an ohmmeter indication or the indication is

intermittent, before replacing the battery or fuse, lightly sand the base

of the battery with fine sandpaper. This will remove any oxidation that

could be causing poor or intermittent contact.

HOW TO USE AS AN OHMMETER

IMPORTANT:

Read "Precaution for Personal and Instrument Safety"

before using instrument.

FOR RS-3 MODELS

CAUTION:

Make certain no voltage is present in circuit before connecting ohmmeter.

The ohmmeter is fused to help protect it against a misapplication of voltage

but under certain conditions it is still possible to damage the meter and/or

cause personal injury. Use only OHB-3HE ohmmeter attachment with fuse

#8AG-360x023. 1 Amp 600V.

1. Insert either the Red or Black Voltage

Lead into the Left Voltage Receptacle

at bottom of instrument case (Fig. 14).

Fig 14

2. Insert ohmmeter battery/fuse attachment

into the jack on the right side of the

instrument just below the ohmmeter Zero

Adjust Knob. Seat plug to bottom for

good connection (Fig. 15).

3. Set range Selector so that the 150 volt

red scale appears in window.

4. Ohmmeter Scale Adjustment with test

Leads Open-Pointer should line up with

division marked "∞" on OHMS SCALE.

Turn Pointer Zero Adjust Screw if neces-

sary (Fig. 16).

6. To Measure Resistance

between any two points on a

device, simply apply the clip lead

Lid

and the ohmmeter attachment

probe tip and read pointer.

CAUTION: Makecertainthatcircuit

is disconnected from line before

takinganyresistance measurements.

HOW TO READ OHMMETER SCALE

The ohmmeter scale is located on the flat plate along the righthand edge of the

window. The zero mark (beginning) is on top of the scale while the infinity mark

"∞" ends the scale.

OPTIONALEXTENDO LEADS

FOR FASTER AND EASIER VOLTAGE TESTING

EXTENDO TESTLEADS. Cal. No VLK-411R. have

5 inch long insulated probes for a man-sized grip.

One probe clamps between instrument jaws.

Optional alligator clip adaptor (Cat No VRC-320)

converts probe so it can be fastened to test point.

Probe tips are replaceable (Cat No VPT) Fig 19
