INSTALLING/REPLACING THE BATTERY

Your meter requires a 9V battery (not supplied) for power.  For reliable
operation, we recommend an alkaline battery, such as Radio Shack
Cat. No. 23-553.

Warning:  TO AVOID ELECTRIC SHOCK, DISCONNECT BOTH LEADS FROM ANY
          EQUIPMENT BEFORE YOU REMOVE OR INSTALL THE BATTERY.

Follow these steps to install the battery:

1.  Turn off power and disconnect the two test probes.

2.  Loosen the battery compartment cover screw and slide off the cover.
    Remove the old battery, if necessary.

3.  Place the battery into the supplied insulation capsule and snap it
    onto the contacts.

Warning:  Do not discard the provided battery insulation capsule.  If you
          do not use this insulation capsule properly, damage or injury
          might result.

4.  Replace the battery compartment cover and secure it with the screw.

WARNING:  DO NOT OPERATE THE METER UNTIL YOU REPLACE THE BATTERY AND CLOSE
          THE BATTERY COMPARTMENT COVER.

Notes:  When the battery indicator appears, replace the battery.

        Never leave a weak or dead battery in your meter.  Even a
        leakproof battery can leak damaging chemicals.  When you are not
        going to use your meter for a week or more, remove the battery.

USING THE TEST PROBES

Use only the type of test probes supplied with your meter.  These test
probes are rated for 1200 volts.  You can purchase replacement probes from
your local Radio Shack store.

Cautions:  Although the test probes are rated for 1200 volts, the maximum
           rating of your meter is 1000 volts DC and 750 volts AC.  If you
           try to measure DC voltages above 1000 volts or AC voltages
           above 750 volts, you might damage your meter and expose
           yourself to a serious shock hazard.  Use extreme care when you
           measure high voltages.

           Never connect the probe you plug into the COM terminal to a
           source of voltage greater than 500 volts with respect to each
           ground.  This creates a serious shock hazard.

USING THE STAND

Use your meter's stand to prop up or hang the meter.

Propping Up the Meter

If you prop up the meter on a benchtop, the stand helps provide a better
viewing angle.  To use the stand as a prop, just open it away from the
meter and set it on a flat surface.

Hanging the Meter

To hang the meter, remove the stand by pressing the power parts of the
stand together.  Then insert the stand into the top two holes as shown.

PRE-OPERATION CHECK

To ensure correct operation and familiarize yourself with the meter,
follow these steps before you use it.

1.  Press POWER to turn on the meter.  The meter beeps once.

2.  Plug the black probe into the meter's COM terminal and the red probe
    into the meter's V/ohm terminal.

3.  Rotate the function selector to MUSIC SYMBOL.  Your meter displays OL
    and the analog bargraph flashes.

4.  Touch the probe tips together.  Your meter sounds a tone.

5.  Rotate the function selector to one of the other OHM positions.  Your
    meter displays a value of less than 1 ohm when you touch the probe
    tips together.
