Temperature Measurements; Capacitance Measurements - Extech Instruments EX530 User Manual

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.

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 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.
3. Touch the test leads to the capacitor to be tested.
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.
4. Read the frequency on the display.
5. Press the MODE button to indicate "%".
6. Read the % duty cycle in the display.
