Introduction
Congratulations on your purchase of the Extech RC200 RC Tweezers Multimeter This meter, using the
tweezers adaptor, measures SMD capacitors, resistors, diodes and continuity test. With the test lead
adaptor, it measures AC/DC Voltage. Proper use and care of this meter will provide many years of
reliable service.

INTERNATIONAL ELECTRICAL SYMBOLS
Caution ! Refer to the explanation in this Manual
Caution ! Risk of electric shock
Earth (Ground)
Double Insulation or Reinforced insulation
This meter has been designed for safe use, but must be operated with caution. The rules listed
below must be carefully followed for safe operation.
1. NEVER measure voltage with the Tweezer adaptor installed.
2. NEVER apply voltage or current to the meter that exceeds the specified maximum:
Input Protection Limits
Function Maximum Input
V DC or V AC 600V DC/AC
3. USE EXTREME CAUTION when working with voltages greater than 25VAC or 35VDC. These
voltages are considered a shock hazard.
4. DO NOT measure voltage if the voltage on the "COM" input jack exceeds 600V above earth
ground.
5. NEVER connect the meter leads across a voltage source while the function switch is in the
capacitance, resistance, or diode mode. Doing so can damage the meter.
6. ALWAYS discharge filter capacitors in power supplies and disconnect the power when making
capacitance, resistance, continuity or diode tests.
7. ALWAYS turn off the power and disconnect the test leads from the circuit before opening the
cover to replace the batteries.
8. NEVER operate the meter unless the battery cover is in place and fastened securely.
9. NEVER operate the meter if any part is damaged.
10. ALWAYS turn the meter off when not in use.

Operating Instructions
WARNING: Risk of electrocution. High-voltage circuits, both AC and DC, are very dangerous and
should be measured with great care.
1. If “OL” appears in the display during a measurement, the value exceeds the range you have
selected. Change to a higher range.
2. The meter will automatically recognize if the voltage test leads or tweezers adaptor is inserted.
3. The meter will turn on with autoranging “AUTO” selected. In this mode, the unit will automatically
select the proper range to measure the device under test. Press the “RANGE” button to go to
manual (“MANU”) ranging. Continue pressing the button until the range desired is selected. Press
and hold the RANGE button for two seconds to return to autoranging.
4. On some low AC and DC voltage ranges, with the test leads not connected to a device, the
display may show a random, changing reading. This is normal and is caused by the high-input
sensitivity. The reading will stabilize and give a proper measurement when connected to a load.
Test Lead AC/DC Voltage Measurements
1. Insert the voltage adaptor into the meter observing the polarity indicators.
2. Press the MODE button for 2 seconds until the meter beeps. “V” will be displayed on the LCD
3. Press the MODE button to select either AC or DC voltage.
4. Touch the black test probe tip to the negative side of the circuit.
Touch the red test probe tip to the positive side of the circuit.
5. Read the voltage in the display.
Note: The “ “ DANGER symbol will appear in the display whenever the measured voltage exceeds
30V
WARNING: To avoid electric shock, disconnect power to the unit under test and discharge all
capacitors before taking any capacitance or resistance measurements. Remove the batteries and
unplug line cords.
Tweezer Resistance, Capacitance, Continuity and Diode Measurements.
1. Insert the tweezers adaptor into the meter observing the polarity indicators.
2. Press the MODE button for 2 seconds until the meter beeps. The meter turns on in the SCAN
mode and “- - - -“ on the display.
3. Insert a component into the tweezers contacts. In the SCAN mode, the meter automatically
selects the proper range and units (Capacitance or Resistance).
4. Read the measurement results in the display.
5. Press the MODE button to exit the SCAN mode and begin resistance measurements. The “Ω”
icon will appear on the display.
6. Press the MODE button for continuity measurements. The icon will appear on the display. The
meter will beep if the resistance is less than the continuity threshold.
7. Press the MODE button for diode measurements. The icon will appear on the display. A good
diode will read “OL” in one direction and a low voltage in the opposite direction.
8. Press the MODE button for capacitance measurements .The “F” icon will appear on the display. It
can take several minutes for the reading to stabilize at the final value for large value capacitors.
9. Press the MODE button again to return to the SCAN mode.

Power OFF and Auto Power OFF
Press and hold the MODE button for 4 seconds to manually turn power off. The auto off feature will
automatically turn the meter off after approximately 10 minutes of inactivity..
Low Battery Indication
The icon will appear in the display when the battery voltage becomes low. Replace the battery
when this appears.
Maintenance
1. KEEP THE METER DRY. If it gets wet, wipe it off.
2. USE AND STORE THE METER IN NORMAL TEMPERATURES. Temperature extremes can
shorten the life of the electronic parts and distort or melt plastic parts.
3. HANDLE THE METER GENTLY AND CAREFULLY. Dropping it can damage the electronic
parts or the case.
4. KEEP THE METER CLEAN. Wipe the case occasionally with a damp cloth. DO NOT use
chemicals, cleaning solvents, or detergents.
5. USE ONLY FRESH BATTERIES OF THE RECOMMENDED SIZE AND TYPE. Remove old or
weak batteries so they do not leak and damage the unit.
6. IF THE METER IS TO BE STORED FOR A LONG PERIOD OF TIME, the batteries should be
removed to prevent damage to the unit.
BATTERY INSTALLATION
1. Turn power off.
2. Open the rear battery cover by removing the two Phillips head screws located on the rear of the
meter.
3. Insert the batteries into battery holder, observing the correct polarity.
4. Put the battery cover back in place. Secure with the screws.
5.
You, as the end user, are legally bound (Battery ordinance) to return all used batteries and
accumulators; disposal in the household garbage is prohibited!
You can hand over your used batteries / accumulators at collection points in your community
or wherever batteries / accumulators are sold!
Disposal: Follow the valid legal stipulations in respect of the disposal of the device at the
end of its lifecycle
NOTE: If your meter does not work properly, check the batteries to make sure that they are still
good and that they are properly inserted.
