Introduction
Congratulations on your purchase of the Extech RC100
SMD Tweezers. This device offers rapid and accurate
capacitance and resistance measurements of chip
components. This meter is shipped fully tested and
calibrated and, with proper use, will provide years of
reliable service.
Precautions and Safety measures
When using this meter, the user must observe all normal
safety rules
•Allow a 30 seconds warm-up before use.
•If the meter is used near noise generating
equipment the display may become unstable or
indicate large errors.
•Do not use the meter if it appears damaged.
•Use the meter only as specified in this manual;
otherwise, the protection provided by the meter may
be impaired.
•Do not operate the meter near explosive gas, vapor,
or dust.
•To avoid damages to the instrument, do not exceed
the maximum limits of the input values.
•Caution: Don't use this device if working voltage is
above 50V DC or 36 V AC rms. Such voltages pose
a shock hazard and damage the meter
•When using this meter, keep your fingers away from
the metal of the meter.
•Before changing functions, disconnect the test clip
from the circuit under test.
•Replace the battery when the symbol
appears. With a low battery, the meter might
produce false readings.

Caution: refer to the instruction manual.
Incorrect use may result in damage to the
device or its components.

Operation
Resistance
To avoid electrical shock or damage to
the meter, disconnect circuit power and
discharge all high-voltage capacitors
before measuring resistance.
1. Press the MODE key to select the mode.
2. Connect the test tips to the object being tested
and read the measured value on the display.
NOTE:
a. When measuring the high-resistance (> 1MΩ), it
may take a few seconds for the reading to
stabilize, this is normal.
b. When the input is not connected, i.e. an open
circuit, the "OL" (overange) icon will be
displayed.
Capacitance
To avoid electrical shock or damages to
the meter under test, disconnect circuit
power and discharge all high-voltage
capacitors before measuring capacitance.
1. Press the MODE key to select the mode.
2. Connect the test clips to the capacitor being
tested and read measured value on the display.
NOTE:
a. When measuring large valued capacitors
(200uF range), it may take up to 30 seconds for
the reading to stabilize, this is normal.
b. To improve the accuracy of measurements less
than 4nF, subtract the residual capacitance of
the meter and tips by pressing the REL key with
the tips open circuited.

Diode measurement
To avoid electrical shock or damage to
the meter, disconnect circuit power and
discharge all high-voltage capacitors
before testing diodes.
1. Press the MODE key to select the mode.
2. Connect the + tip to the anode and the - tip to the
cathode of the diode under test.
3. The meter will show the approx. forward voltage
of the diode. If the lead connection is reversed
"OL" displayed.

Maintenance
General Maintenance
Periodically wipe the case with a damp cloth and mild
detergent. Do not use abrasives or solvents.
Battery replacement
Before replacing the battery, disconnect test
tips from any circuit under test
Use the following procedure:
When the battery voltage drop below proper operation
range the symbol will appear on the LCD display
and the battery need to be replaced.
1. Slide the battery cover in the direction of the
arrow to open the battery cover.
2. Replace the battery with two new 1.5V batteries
(AG13).
3. Replace the battery cover.
