Warning
Do not enter a temperature higher than 60V AC voltage 30V AC
voltage to avoid damage or instrument damage
1) Connect the negative terminal (black) and the positive terminal (red) of the K type
thermocouple to the COM input jack and input jack separately.
2) Press enter to temperature mode;
3) The other end of the thermocouple (test side) close to the surface of the measured object.
4) To be read by the liquid crystal display to read the measured temperature value.
Note
：
K-type thermocouple distribution of the highest measurement temperature of 250
4.14 Non - contact voltage measurement
（
NCV)
Press button,
the instrument displays “
NCV
”
or "EF" symbol, and the top of the
instrument is close to the object to be tested such as mains, power switch, socket and so on.
When the detected voltage is greater than 110V (AC RMS), the instrument NCV indicator will be
lit and the buzzer will sound an alarm.
note:
1) The voltage may still be present even if there is no indication. Do not rely on non-contact
voltage detectors to determine if there is voltage on the shielded wire. The detection operation
may be affected by factors such as socket design, insulation thickness and type.
2) When the instrument input terminal input voltage, due to the presence of induced voltage, the
voltage sensor indicator may also be bright.
3) External sources of interference (such as flash, motor, etc.) may be mistakenly triggered by
non-contact voltage detection.
