Series III Multimeter

Instruction Sheet

Read First: Safety Information

WTo avoid damage to the meter, electric shock or injury:

•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.

•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.

WWarning

To avoid false readings, which could lead to possible

electric shock or personal injury, replace the battery

as soon as the low battery indicator (M) appears.

Pushbutton

Use the pushbutton to either select a fixed range or put the meter

in the Automatic Touch Holdmode.

Autorange

The meter defaults to autorange when first turned on.

Manual Range

Manual ranging is available in V ac, V dc, ohms, A ac, and A dc.

The manual range mode and Touch Hold mode are mutually

exclusive. MAN is displayed when the meter is in the manual

range mode.

Automatic Touch Hold Mode

WWarning

To avoid electric shock, do not use the Touch Hold

mode to determine if a circuit with high voltage is

dead. The Touch Hold mode will not capture

unstable or noisy readings.

The Touch Hold mode automatically captures and displays stable

readings. Press Rfor 2 seconds. HOLD is displayed when

the meter is in the Touch Hold mode.

measurement function. The Touch Hold mode and manual range

mode are mutually exclusive.

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

WWarning

To avoid injury, do not attempt a current

measurement if the open circuit voltage is above the

rated voltage of the meter.

To avoid blowing an input fuse, use the 10 A jack until you are

sure that the current is less than 300 mA.

Turn off power to the circuit. Break the circuit. (For circuits of

more than 10 amps, use a current clamp.) Put the meter in series

with the circuit as shown and turn power on.

Maintenance

WWarning

To avoid electric shock, personal injury, or damage to

the meter:

•Do not service this product other than as described

in this Instruction Sheet unless you are a qualified

technician and have the required equipment and

service information.

•Remove any input signals prior to removing test

leads and opening case.

•When servicing the meter, use only specified

replacement parts.

•Do not allow water to get in the case.

WCaution

To avoid damaging meter components, lift up the

end of the battery as shown.

To avoid contamination or static damage, do not

touch the circuit board without proper static

protection.

For maintenance procedures not described in this Instruction

Sheet, contact a Fluke Service Center.
