4-5. 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.
• Set the rotary function switch to the CAP position.
• Insert the black test lead banana plug into the negative COM jack.
Insert the red test lead banana plug into the positive V jack.
• Touch the test leads to the capacitor to be tested.
• Read the capacitance value in the display
4-6. Frequency measurements - AC Only
• Set the rotary function switch to the “ Hz ” position.
• Insert the black lead banana plug into the negative COM jack and the red test
lead banana plug into the positive V jack.
• Touch the test probe tips to the circuit under test.
• Read the frequency on the display.
4-7. Temperature Measurements
WARNING:
To avoid electric shock, disconnect both test probes from any source
of voltage before making a temperature measurement.
• Set the function switch to
TEMP .
• Insert the Temperature Probe into the negative COM and the V jacks, making
sure to observe the correct polarity.
• Touch the Temperature Probe head to the material surface you intend to measure.
Keep the probe touching the part under test until the reading stabilizes (about
30 seconds).
• Read the temperature in the display. The digital reading will indicate the proper
decimal point and value.
WARNING: To avoid electric shock, be sure the thermocouple has been removed
before changing to another measurement function
4-8. Battery Replacement
• Remove the one rear Phillips head screw
• Open the battery compartment
• Replace the Requires One 9V battery
• Re-assemble the meter
