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
specications. If a certicate 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 difcult 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.
