If the function selector is set to R1KΩ, multiply that reading by 1000 to compute the resistance. For example, if the needle points

to 1, the resistance is 1000 ohms (1 1000 = 1000Ω).

Hint: If you are identifying cathode and anode ends or the type of transis- tor (PNP or NPN), the actual polarity of the multimeter's voltage is the op- posite of the polarity suggested by the test probes' color. The red test probe is the negative source, and the black test probe is the positive source.

ˆCare

Keep the multimeter dry; if it gets wet, wipe it dry immediately. Use and store the multimeter only in normal temperature environments. Handle the multimeter carefully; do not drop it. Keep the multimeter away from dust and dirt.

Modifying or tampering with the multi- meter’s internal components can cause a malfunction and might invali- date its warranty. If your multimeter is not performing as it should, take it to your local RadioShack store for assis- tance.

CLEANING

To keep the multimeter looking new, occasionally wipe it with a cloth slight- ly dampened with water. Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the mul- timeter.

WARNINGS:

DO NOT LET ANY WATER DRIP INSIDE THE MULTIMETER WHILE CLEANING IT.

MAKE SURE THAT THE MULTI- METER IS COMPLETELY DRY BEFORE USING IT.
