Introduction

Thank you for purchasing your REED R5020 AC Clamp Meter. Please

read the following instructions carefully before using your instrument. By

following the steps outlined in this manual your meter will provide years of

reliable service.

Product Quality

This product has been manufactured in an ISO9001 facility and has been

calibrated during the manufacturing process to meet stated product

specications. If a certicate of calibration is required please contact the

nearest authorized REED distributor or authorized Service Center. Please

note an additional fee for this service will apply.

Safety

• Never attempt to repair or modify your instrument. Dismantling your

product, other than for the purpose of replacing batteries, may cause

damage that will not be covered under the manufacturer's warranty.

Servicing should only be provided by an authorized service center.

• Do not exceed the maximum allowable input range of any function.

• Do not apply voltage to the meter when resistance function

is selected.

• Set the rotary switch to OFF when the meter is not in use.

• Set the rotary switch to the appropriate position before measuring.

• When measuring volts do not switch to current/resistance modes.

• Disconnect the test leads from the circuit under test before changing

the position of the rotary switch.

• Do not exceed the maximum rated input limits.

• Improper use of this meter can cause damage, shock, injury or death.

• Always remove the test leads before replacing the battery.

• Inspect the condition of the test leads and the meter itself for any

damage before operating.

• Use great care when taking measurements if the voltages are greater

than 25VAC RMS or 35VDC as they are considered a shock hazard.

• Remove the battery if the meter is to be stored for a long period of time.

• Always discharge capacitors and remove power from the device

under test before performing diode, resistance, or continuity tests.

• Voltage checks on electrical outlets can be difcult and misleading

because of the uncertainty of connection to the recessed

electrical contacts.

Operating Instructions

Connecting the Test Leads

Connect the red test lead to the VΩ Input Jack and the black test lead to

the COM Input Jack.

AC Current Measurements

Warning:

Disconnect the test leads before making clamp measurements.

1. Set the rotary switch to the 400 or 40A

range. If the required range is unknown,

select the higher range rst then move

to the lower range

if necessary.

2. Press the trigger to the open jaw and

fully enclose one conductor only

as shown.

3. The LCD will display the reading.

AC/DC Voltage Measurements

1. Set the rotary switch to the V position, and select

either AC or DC using the MODE button.

2. Connect the test leads to the meter (see Connecting

the Test Leads section for details).

3. Connect the test leads in parallel to the circuit under

test as shown.

4. The LCD will display the reading.

Resistance Measurements

1. Set the rotary switch to the Ω position.

2. Connect the test leads to the meter (see Connecting

the Test Leads section for details).

3. Touch the test probe tips across the circuit or

component under test as shown.

Note: It is best to disconnect one side of the device under test so the

rest of the circuit will not interfere with the reading.

4. The LCD will display the reading.

Diode and Continuity Measurements

1. Set the rotary function switch to the Ω position.

2. Connect the test leads to the meter (see Connecting the Test Leads

section for details).

3. Press the MODE button until the Diode Test indicator appears on

the LCD display.

4. Touch the test probes to the diode under test as shown.

Forward voltage will indicate 0.4V to 0.7V. Reverse voltage will be

indicated by "OL". Shorted devices will indicate near 0mV and an

open device will be indicated by "OL" in both polarities. For

Continuity tests, if the resistance is <150, a tone will sound.
