Introduction

Thank you for purchasing your REED R5710 Ground Resistance Tester.

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 ISO 9001 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.

• Be aware of your surroundings, environment and measurement scope.

• If the instrument applies to ground resistance testing instead of current

power frequency wire it will affect the clamps magnetic property and

the accuracy of measurement.

• Before turning on the unit, press on the trigger a couple of times to

conrm it can properly open and close.

• Do not press the trigger or clamp any wires when turning on the instrument.

• Only clamp the tested desired object after the display shows "OL Ω".

• Keep the contact surface of the jaws clean and refrain from using harsh

cleaning products.

• When taking measurements the instrument will sporadically "hum".

• Do not exceed the max measurements.

• If instrument will not be used for a prolonged amount of time, remove

the battery.

• If something is damaged, immediately stop using the instrument.

Operating Instructions

Power ON/OFF

1. To turn the instrument ON/OFF press the button.

2. At power up, the LCD display will light up while displaying the symbols

shown below.

3. During that time, the instrument will also go through a quick internal

calibration and enter resistance/ground leakage measurement mode

if it passes. Refer to Resistance/Ground Leakage Measurement

Mode for details.

Note: The instrument automatically enters the resistance/earth leakage

measurement mode at start up regardless of the last saved setting.

Note: DO NOT clamp on to any conductor or open the clamp jaws during

the start-up self-calibration.

4. If the instrument does not pass calibration, the LCD display will indicate

"ER" as shown below.

Note: This error could be caused by the clamp jaw not being properly

closed or from any dirt build up on the metal surface of the jaw clamp.

Auto Power OFF

To preserve battery life, the instrument is programmed to turn itself OFF

after 5 minutes of inactivity. Prior to the instrument turning OFF, the LCD

display will blink for approximately 30 seconds. Press the button to

delay the auto power OFF function and resume normal operation.

Resistance/Ground Leakage Measurement Mode

When instrument is turned on and passes calibration, "OL Ω"

and "0.00 mA" appears on the LCD display as shown below

conrming that you can now measure the resistance/earth leakage

simultaneously.

2. Pull the trigger to open the clamp and clamp onto the circuit

under test.

3. The LCD will display the resistance and ground leakage current

measurement values.

4. If the instrument beeps and the LCD display ashes, the

measurement values are exceeding the critical set alarm. Refer to

Setting the Critical Alarms for details.

Resistance Measurement Mode

1. After the instrument has powered up and passed calibration, press

the MODE button to enter the resistance only measurement mode.

2. "OL Ω" appears on the LCD display as shown below conrming that

you can now measure the resistance.

3. Pull the trigger to open the clamp and clamp onto the circuit

under test.

4. The LCD will display the resistance value.

5. If the instrument beeps and the LCD display ashes, the resistance

measurement is exceeding the critical set alarm. Refer to Setting the

Critical Alarms for details.
