4.Place the battery in the compart- ment as indicated by the polarity symbols (+ and –) marked inside.

5.Replace the back cover and the top cover, then secure them with the screws.

When you cannot adjust the needle to point to 0 on the scale when you mea- sure resistance (see “Measuring Re- sistance” on Page 16) or the multimeter stops operating properly, replace the battery.

Warning: Dispose of old batteries promptly and properly. Do not burn or bury them.

Caution: If you do not plan to use the multimeter for a month or more, re- move the battery. Batteries can leak chemicals that can destroy electronic parts.

CONNECTING THE TEST LEADS

The test leads supplied with your mul- timeter are rated for 1000 volts. Use only test leads of the same rating with the multimeter. You can order re- placement leads from your local RadioShack store.

WARNING: ALTHOUGH THE TEST LEADS ARE RATED FOR 1000 VOLTS, THE MAXIMUM RATING OF THIS MULTIMETER IS 500 VOLTS DC/500 VOLTS RMS AC. DO NOT TRY TO MEASURE ANY VOLTAGE GREATER THAN 500 VOLTS DC/ 500 VOLTS RMS AC.

Plug the black test lead’s right-angled end into the multimeter’s (common) jack, then plug the red test lead’s right-angled end into the + jack.

CONNECTING THE AC AMMETER TO THE MULTIMETER

Cautions:

Always connect the ammeter to your multimeter before you clamp the ammeter to a wire car- rying current.

Always unclamp the ammeter from a wire carrying current before you disconnect it from the multimeter.

1.Use a Phillips screwdriver to remove the screw on the upper back of the multimeter. Then pull up the top cover to remove it.

2.Insert the four pins on the amme- ter as far as they will go into the top of the multimeter, then gently press the ammeter down onto the top of the multimeter until it clicks.
