6. Read the display. If 0L appears on the highest Range, the resistance is too large to be

measured or the circuit is an open circuit.

Testing for Continuity (See fig. 2)

1. Set the Function Switch to Ω and press the SELECT button until � is displayed.

2. Connect the test leads: Red to +, Black to COM.

3. Turn off power to the circuit being measured.

4. Discharge any capacitors that may influence the reading.

5. Connect the test probes across the resistance or the two points of test.

6. Listen for the tone that indicates continuity (>10 Ω and < 120 Ω).

Testing Diodes (See fig. 2)

1. Set the Function Switch to Ω and press the SELECT button until  is displayed.

2. Connect the test leads: Red to +, Black to COM.

3. Turn off power to the circuit being measured.

4. Free at least one end of the diode from the circuit.

5. Connect the test probes across the diode.

6. Read the display. A good diode has a forward voltage drop of about 0.6 V. An open or

reverse biased diode will read .0L.

MAINTENANCE AND REPAIR

If there appears to be a malfunction during the operation of the meter, the following steps

should be performed in order to isolate the cause of the problem:

1. Check the battery.

2. Review the operating instructions for possible mistakes in operating procedure.

3. Inspect and test the test leads for a broken or intermittent connection.

Except for the replacement of the battery or test probes, repair of the multimeter should

be performed only by a Factory Authorized Service Center or by other qualified instrument

service personnel. The front panel and case can be cleaned with a mild solution of detergent

and water. Apply sparingly with a soft cloth and allow to dry completely before using. Do not

use aromatic hydrocarbons or chlorinated solvents for cleaning.

battery Replacement (see fig. 4)

� Warning

To prevent electrical shock or meter damage, disconnect the meter's test leads from any

circuit and the meter, then turn the meter off before removing the battery cover. battery

replacement should be performed in a clean environment and with appropriate care taken to

avoid contaminating the meter's interior components.

1. Remove the screws and lift the battery cover.

2. Replace the battery with the same type, 3V coin battery (ANSI/NEDA-5004LC, IEC-CR2032).

Note polarity of the battery.

3. Replace the rear case and screws.
