CAPACITANCE MEASUREMENTS

WARNING: 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.
1. Set the rotary function switch to the Ω CAP
position.
2. Insert the black test lead banana plug into the COM jack.
3. Insert the red test lead banana plug into the V jack.
4. Touch the test leads to the capacitor to be tested. Read
the capacitance value in the display

TEMPERATURE MEASUREMENTS

1. Set the function switch to the "Temp" positive and press
the MODE key to select the "°C" measuring or "°F"
measuring.
2. Insert the Temperature Probe into the input jacks, making
sure to observe the correct polarity.
3. Touch the Temperature Probe head to the part
whose temperature you wish to measure. Keep the
probe touching the part under test until the reading
stabilizes (about 30 seconds).
4. Read the temperature in the display.
Note: The temperature probe is fitted with a type K
mini connector. A mini connector to banana connector
adaptor is supplied for connection to the input banana
jacks.

FREQUENCY MEASUREMENT

1. Set the function switch to the Hz/Duty position.
2. Insert the black test lead banana plug into the negative ( - ) jack (COM) and
the red test lead banana plug into the positive ( + ) jack (°F).
3. Touch the test probe tips to the circuit under test.
4. Read the frequency in the display. The digital reading will indicate the
proper decimal point, symbols (Hz, kHz, MHz ) and value.
NOTE: Press the MODE key to select the frequency or the duty cycle
measuring.
