TEMPERATURE MEASUREMENTS

1. Set the function switch to the green Temp position.

2. Insert the Temperature Probe into the input jacks, making sure to

observe the correct polarity.

3. Press the MODE button to indicate “ºF” or “ºC”

4. 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).

5. 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.

Note: The temperature range of the supplied thermocouple probe is -20 to 250°C (-4 to

482°F)

discharge all capacitors before taking any capacitance measurements. Remove the

batteries and unplug the line cords.

1. Set the rotary function switch to the green CAP position.

2. Insert the black test lead banana plug into the negative

COM jack.

Insert the red test lead banana plug into the positive V

jack.

4. Read the capacitance value in the display

FREQUENCY (DUTY CYCLE) MEASUREMENTS (ELECTRONIC)

1. Set the rotary function switch to the green Hz/% position.

2. Insert the black lead banana plug into the negative COM jack

and the red test lead banana plug into the positive Hz jack.

3. Touch the test probe tips to the circuit under test.
