Hazards or unsafe practices which, if not avoided, COULD result in minor

personal injury or property damage.

Hazards or unsafe practices which, if not avoided, COULD result in severe

personal injury or death.

Immediate hazards which, if not avoided, WILL result in severe personal

injury or death.

SAFETY ALERT SYMBOL

The symbol above is used to call your attention to instructions concerning

your personal safety. Watch for this symbol. It points out important safety

precautions. It means “ATTENTION! Become alert! Your personal safety is

involved!” Read the message that follows and be alert to the possibility of

SAVETHESE INSTRUCTIONS

Additional copies of this manual are available upon request at no extra charge.

• Do not use the meter if it is wet or damaged. Electric shock can

result.

• Do not apply more than 500 VAC/VDC between any terminal and

earth ground. Electric shock can result.

• Do not attempt to measure more than 750 VAC or 1000 VDC. Electric

shock can result.

• Do not measure current in circuits with more than 250 VAC/VDC or

in circuits which have a maximum load exceeding 4000 VA and fuse

protection greater than 16 amps. Electric shock can result.

• Do not connect the meter to a source of voltage or current when the

range selector is in an Ωor the position. Electric shock

can result.

• Do not use for IEC 664 Overload Range III installations. Electric

shock can result.

Failure to observe these warnings may result in serious injury or death.

SAFETY INFORMATION

Electric shock hazard:

Contact with live circuits can result in severe

injury or death.

93-604 Multimeter

• Do not open the case while the test leads are connected to the

circuit or while the meter is on. Damage to the meter can result.

• Do not change the position of the selector switch when the test

leads are connected to a component or circuit. Damage to the

meter can result.

• Do not attempt to repair this test instrument. It contains no

user-serviceable parts.

• Do not expose meter to extremes in temperature or high humidity.

Damage to the meter can result. See Specifications section of this

manual.

Failure to observe these precautions may result in minor injury and/or

damage to this instrument.

SAFETY INFORMATION (cont’d)

• Use only properly rated fuses when replacement is necessary.

See the Specifications section of this manual.

• Replace weak or discharged batteries as soon as either of these

conditions is detected.

• This meter is not equipped with an EMI shield. Using this meter in

areas with high-frequency fields nearby may cause inaccurate

readings.

DESCRIPTION

The measurement functions and ranges are as follows:

AC Voltage: 0–750 volts AC Current: 0–20 amps

DC Voltage: 0–1000 volts DC Current: 0–20 amps

Resistance: 0–20 megohms

Continuity Check

Diode Check

Battery Check: 1.5-volt and 9-volt batteries

PURPOSE

This instruction manual is intended to familiarize operators with the safe operation of the

Greenlee 93-604 Multimeter. This manual should be kept available to all operating personnel.

OPERATION

Preparation For Use

Before using the test instrument, check the meter with a functioning circuit or component. If

the test instrument fails to perform as expected, refer to the following troubleshooting list until

the problem is solved:

1. Plug the test leads completely into the input terminals.

2. Remove corrosion from the lead tips and connectors.

3. Replace the battery.

4. Replace the test leads.

5. Send the test instrument in for repair. See the Warranty section of this manual for shipping

instructions.

93-604 Multimeter

Do not attempt to measure more than 750 VAC or 1000 VDC. Electric

shock can result.

Failure to observe this warning may result in serious injury or death.

Voltage Measurement

Electric shock hazard:

Contact with live circuits can result in severe

injury or death.

Do not change the position of the selector switch when the test leads

are connected to a component or circuit. Damage to the meter can

result.

1. Plug the black test lead into the COM input terminal, and plug the red test lead into the

V/Ωinput terminal.

2. Set selector switch to the appropriate range.

Note: When measuring an unknown voltage, start at the highest range.

3. Touch the test leads to the circuit under test and read the display.

Note: If the resolution of the reading is not satisfactory, disconnect the meter from the circuit

and switch to the next lower range. Reconnect the meter to the circuit and read the

display. Repeat this procedure until the resolution is satisfactory.

Do not measure current in circuits with more than 250 VAC/VDC or in

circuits which have a maximum load exceeding 4000 VA and fuse

protection greater than 16 amps. Electric shock can result.

Failure to observe this warning can result in serious injury or death.

Current Measurement

Electric shock hazard:

Contact with live circuits can result in severe

injury or death.

1. Shut off and disconnect power to the circuit to be tested.

2. Open the branch of the circuit where the current is to be measured.

3. Plug the black test lead into the COM input terminal, and plug the red test lead into the

appropriate current input terminal.

Note: When measuring an unknown current, start with the red test lead plugged into the

20A input terminal.

4. Set selector switch to the appropriate

ACA

DCA

range.

Note: When measuring an unknown current, start at the 20A range.

5. Connect the test leads to the circuit.

6. Apply power to the circuit under test and read the display.

Note: A current measurement of 20 amps must not exceed 30 seconds and may not be

repeated more frequently than 15-minute intervals.

Note: If the resolution of the reading is not satisfactory, shut off power to the circuit and

switch to the next lower range. Turn on the power to the circuit and read the display.

Repeat this procedure until the resolution is satisfactory.

Note: If the range selector must be changed from 20A range to the 200 mA range to obtain

finer resolution, you must also unplug the red test lead from the 20A input terminal and

plug it into the mA input terminal.

7. Shut power off and disconnect the meter from the circuit.

8. Reconnect the circuit.
