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.

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.

Capacitance Measurements
1. To avoid electric shock, disconnect power to the
unit under test and discharge all capacitors before
taking any capacitance measurements. Remove the
batteries and unplug the line cords.
2. Set the rotary function switch to the CAP position.
3. Connect the test leads to the meter (see Connecting
the Test Leads section for details).
4. Touch the test leads to the capacitor under test as shown.
5. Note the capacitance value on the LCD display.
Frequency or % Duty Cycle measurements
1. Set the rotary function switch to the V position.
2. Connect the test leads to the meter (see Connecting
the Test Leads section for details).
3. Select Hz or % duty with the Hz/% button.
4. Touch the test probe tips to the circuit under test
as shown.
5. Note the frequency or % duty cycle value on the
LCD display.
Type K Temperature Measurements
Note: To avoid electric shock, disconnect both test probes from any
source of voltage before making a temperature measurement.
1. Set the rotary function switch to °C or °F.
2. Plug the optional Type K Thermocouple Probe into the thermocouple
input jack.
3. Touch the Temperature Probe head to the area to be measured.
4. When the reading is stable (up to 30 seconds), note the
measured value.
Note: In case of an open input or a temperature overrange, the meter
will display "OL". To avoid electric shock, be sure the thermocouple has
been removed before changing to another function.

Non-Contact AC Voltage Measurements
1. Set the rotary function switch any measurement position.
2. Place the tip of the meter to the hot conductor under test or the hot
side of the electrical outlet.
3. If AC voltage is present, the detector will light up.
Note: The conductors in electrical cord sets are often twisted. For best
results, rub the probe tip along a length of the cord to assure placing
the tip in close proximity to the live conductor. The detector is designed
with high sensitivity. Static electricity or other sources of energy may
randomly trip the sensor.
Auto Power Off
To preserve battery life, the meter is programmed to turn off after approx.
30 minutes of inactivity.
Data Hold
1. While taking a measurement, press the HOLD button to freeze the
current reading on the display.
2. While in this mode a "HOLD" symbol will appear on the LCD.
3. Press the HOLD button again to resume normal operation.
Relative Mode
1. Press the REL button to enter relative mode which will zero the
reading and create a reference point.
2. REL will appear on the LCD display. Future readings will display a
value that is the difference between the actual reading and the stored
relative reading.
Note: While in Relative mode, auto ranging is disabled and measurements
are limited to the range that is active when the REL button was pressed.
3. Press the REL button to exit relative mode and resume
normal operation.
Note: Relative mode does not function in Frequency or Duty Cycle mode.
