Series III Multimeter

Instruction Sheet

W Read First: Safety Information

To ensure that the meter is used safely, follow these instructions:

• Never use the meter if the meter or test leads look damaged.

• Be sure the test leads and rotary switch are in the correct

position for the desired measurement.

• Never measure resistance in a circuit when power is applied.

• Never touch the probes to a voltage source when the test

leads are plugged into the 10 A or 300 mA input jack.

• To avoid damage or injury, never use the meter on circuits that
exceed 4800 volt-amps.

• Never apply more than the rated voltage between any input
jack and earth ground.

• Be careful when working with voltages above 60 V dc or 30 V
ac rms. Such voltages pose a shock hazard.

• Keep your fingers behind the finger guards on the test probes
when making measurements.

Warning

To avoid false readings, which could lead to
possible electric shock or personal injury, replace
the battery as soon as the battery indicator (N)
appears.

When the meter captures a new input, it beeps and a new
reading is displayed. To manually force a new measurement to
be held, press R.

Note

Stray voltages can produce a new reading.

To exit the Touch Hold mode, turn the meter off.

Bar Graph

The bar graph shows readings relative to the full scale value of a
displayed measurement range and indicates polarity.

Standby

If the meter is on but is inactive for an hour (20 minutes in diode
test), the screen goes blank and displays selected bar graph
segments. To resume operation, turn the rotary switch or press
R.
