3.2.10 Live line test
1. Turn the rotary switch to the position Live.
2. Connect the test lead in red to Live input socket.
3. When a single test lead is inserted into jack L of power socket or
approaches a live conductor, if the meter detects AC voltage, the
meter's indicator for the intensity (high, medium and low) of induced
voltage signal will be on and the beeper sounds alarms for different
intensities.
3.2.11 Measuring temperature
Put the range switch at the gear of
℃
/
℉
. Insert the red plug of the
thermocouple into the end of
℃
, and insert the black plug of the
thermocouple into COM socket. Directly read the temperature value from
the display screen after the reading is stable.
Notes:
The maximum measuring temperature for the K-type thermocouple
dispatched at random is 250
℃
, and its instant measuring value can reach
300
℃
.
