EX570 Datasheet, PDF (10/18 Pages) Extech Instruments Corporation. – True RMS Multimeter with IR Thermometer

THERMOCOUPLE TEMPERATURE MEASUREMENTS
1. Rotate the function switch to the TYPE K position.
2. Insert the Temperature Probe into the input jacks, making sure to
observe the correct polarity.
3. Press the SELECT 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.
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)
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. Rotate the function switch to the 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
1. Rotate t the function switch to the 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 SELECT button to indicate “%”.
6. Read the % duty cycle in the display.
