Measuring Temperature

To avoid electrical shock and damage to the meter when measuring a
temperature, make sure that the surface in contact with the K thermocouple
has no voltage.
1. Turn the rotary switch to
2. Toggle the yellow key to choose
between °C and °F.
3. Plug the K thermocouple into the + and
COM terminal, insuring the
thermocouple plug marked with a +
symbol is connected to the + terminal.
4. Read the temperature in degree on the
display. While doing the measurement
make sure to keep the meter within its
working temperature.
After inserting the plug into the meter, allow 1 minute
for thermal stabilization.
If no thermocouple the meter will display its internal temperature if above 0°C.
If temperature measured is above 1300°C the LCD will display OL.

Non Contact Voltage Detection (NCV)

NCV can only detect AC live voltage referenced to the ground, the Meter may not
detect voltage in NCV due to installation condition of electrical circuit or
equipement. Never touch the circuit under test to avoid possible danger even if
the Meter didn't detect voltage in NCV.
Network : 230V only, 50 Hz (sensitivity : 10 mV)
.
The meter can detect AC live voltage without contact.
1. Remove all test leads from the Meter
2. Turn the rotary switch to
3. Approach live conductor from LCD
(position of the Meter may affect
measurement)
If no AC live voltage is detected the
Meter will display EF and product will
be silent.
If AC live voltage is detected product
will show 4 different levels:
from - to ----, at – buzzer will sound
discontinuously, at ---- buzzer will
sound continuously, and backlight will
blink red. Basic detection voltage is for
220/230V.
NCV is only for indication purpose and
shouldn't be used for measurement, or
to detect the absence of voltage.
The NCV mode has an indicative meaning only and must not be used either for
measuring nor detect the absence of voltage.
An engraved marking on the sheath indicates the position of the antenna for NCV
indication.

VlowZ

The Vlow Z position measures AC voltage with lower impedance (500kΩ) than normal
voltage measurement, this function is used to avoid measuring ghost voltages.
