4 .10 The line of fire test
4.10.1Touch the "Live" key to switch to LIVE gear, the instrument
shows Live
4.10.2Connect the red test pen to the Live input socket. Insert the
single pen into the power socket L jack or close to the live
wire. If the instrument detects ac voltage, it will display
voltage signal strength according to the detected signal
strength, and the buzzer will give alarm sound of different
intensity.
4 .11Capacitance measurement
4.11.1Touch the " " key to switch capacitor gear.
4.11.2Use the other end of the test pen to measure the capacitance
value of the capacitor to be measured and read the measured
value from the LCD.
Note: 1)When measuring large capacitors, a fixed time is
required to stabilize readings.
2)When measuring polar capacitors, pay attention to
the corresponding polarity to avoid damaging the
instrument.
4 . 12Temperature measurement
Touch "SEL" key to switch TEMP file, thermocouple red plug
into the end of °C /°F, black plug into the COM jack. When the
reading is stable, the temperature can be read directly from the
display screen.
Note:
The maximum measurement temperature of type K
thermocouple is 250°, instantaneous measurement up to 300°C.
4.13Diode test
4.13.1 Insert the black stylus into the COM jack and the red stylus
into the " " jack.
4. 13.2 Touch SEL key to switch to diode position.
4.13.3 Connect the red stylus to the diode anode and the black
stylus to the diode cathode for testing.
