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 o f the meter.
Before changing functions, disconnect the test clip from the circuit under test.
Replace the battery when the appears. With a low battery, the meter might produce false readings.

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 (> 1M), 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.
