Temperature Measurements
WARNING: To avoid electric shock, disconnect both test probes from any
source of voltage before making a temperature measurement.
1. Set the function switch to °C °F.
2. Insert the Temperature Probe into the negative (COM) and the V 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. 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
Non-Contact AC Voltage Measurements
WARNING: Risk of Electrocution. Before use, always test the Voltage
Detector on a known live circuit to verify proper operation
1. Touch the probe tip to the hot conductor or insert into the hot side of the
electrical outlet.
2. If AC voltage is present, the detector light will illuminate.
NOTE: The conductors in electrical cord sets are often twisted. For best
results, rub the probe tip along a length of the cord to assure placing
the tip in close proximity to the live conductor.
NOTE: The detector is designed with high sensitivity. Static electricity
or other sources of energy may randomly trip the sensor. This is
normal operation
