To ensure safe operation and usage of the meter, follow these instructions. Failure to
observe warnings can result in severe injury or death.

• To avoid possible electric shock or personal injury, follow these guidelines:

• Do not use the meter if it is damaged. Before you use the meter, inspect the case.

Look for cracks or missing plastic. Pay particular attention to the insulation
surrounding the connectors.

• Inspect the test leads for damaged insulation or exposed metal. Check the test

leads for continuity.

• Replace damaged test leads before you use the meter.

• If this product i s used in a manner not specif ied by the manufacturer, the

protection provided by the equipment may be impaired.

• Do not use the meter if it operates abnormally. Protection may be impaired.

When in doubt, have the meter serviced.

• Do not operate the meter around explosive gas, vapor, or dust.

• Do not apply more than the rated voltage, as marked on the meter, between

terminals or between any terminal and earth ground.

• Before use, verify the meter’s operation by measuring a known voltage.

• When measuring current, turn off circuit power before connecting the meter in

the circuit. Remember to place the meter in series with the circuit.

• Do not attempt to repair this meter. There are no user serviceable parts.

• Use caution when working above 30 V ac rms, 42 V peak, or 60 V dc. Such

voltages pose a shock

• hazard.

• When using the probes, keep your fingers behind the finger guards on the

probes.

• Connect the common test lead before you connect the live test lead. When you

disconnect test leads, disconnect the live test lead first.

• Remove test leads from the meter before you open the battery door.

• Do not operate the meter with the battery door remove d or loosened.

• To avoid false readings, which could lead to possible electric shock or personal

injury, replace the batteries as soon as the low battery indicator (

• Only use a 9 Volt battery, properly installed in the meter case, to power the

meter.

• To avoid the potential for fire or electrical shock, do not connect the

thermocouple to electrically live circuits.

• Disconnect circuit power and discharge all high-voltage capacitors before testing

resistance,continuity, diodes, or capacitance.

Introduction

The AC75 digital clamp-on multimeter, is a fully featured meter that also measures
temperature using a Type K probe (included). The AC75 has full Category safety
ratings and is CAT III, 600 V.

Additional Features

Auto Power Off/Auto Power Off Disable See Figures -2- and –3-
The meter will automatically shut itself off after approximately 10 minutes after

power is turned on, or no activity has occurred with the meter. The meter will beep
when it turns off. Turn the rotary dial to reactivate the meter.

The Auto Power Off feature can be disabled to keep the meter from going to sleep.
Press the BACKLIGHT button and then switch the rotary knob to power on the meter.

Backlight See Figure
The AC75 backlight illuminates the entire display for easy measurement viewing in

dark work environments. The backlight is activated for 60 seconds once the button is
pressed.

HOLD Measurem ents See Figure
The HOLD button allows the meter to capture and continuously display a

measurement reading. To use the HOLD feature, make a measurement, when the
reading has stabilized, press the HOLD button. The measurement value will be
captured on the display. Press the HOLD button again to release the value.

Product Maintenance

Maintenance

Do not attempt to repair this meter. It contains no user serviceable parts. Repair or
servicing should only be performed by qualified personnel.

Cleaning

To clean the meter, periodically wipe the case with a soft moistened cloth. To avoid
damage to the plastic components do not use benzene, alcohol, acetone, ether, paint
thinner, lacquer thinner, ketone or other solvents to clean the meter.

Troubleshooting

If the meter appears to operate improperly, check the following items first.

1. Review the operating instructions to ensure the meter is being used properly.

2. Make sure the battery is in good condition. The low battery symbol

when the battery falls below the level where accuracy is guaranteed. Replace a
low battery immediately.

Battery Replacement

To replace the battery

1. Turn the meter off and remove the test leads.

2. Loosen the screw and remove the battery door.

3. Replace the battery using an alkaline 9 V battery. See General Specifications for

detailed battery specifications.

4. Replace the battery cover and tighten the screw. Recycle the battery using

approved meth ods.

To avoid elect rical, shock remove the tes t leads from both the
meter and the tes t circuit before accessi ng the battery or the fus es.
