4.17 Temperature
• Turn the rotary switch to the °C/°F position. The default setting is °C. Press
to switch to °F if necessary.
• Connect the red(+) end of the K-Type thermocouple to the INPUT jack and the
black(-) end to the COM jack.
• Place the tip of the thermocouple on the surface of the object to be measured.
• Read the measured temperature on the display.
4.18 Non-Contact Voltage (NCV)
Hold down the NCV button and move the tip of the clamp toward the conductor
and the buzzer will beep.
Note:
1. Do not rely solely on NCV detection to determine the presence of voltage.
Detection can be affected by socket design, insulation thickness, or other factors.
2. Interference from outside sources could accidentally trig- ger the NCV detector.
5. Maintenance
5.1 Replacing the batteries
Warning
To avoid electric shock, make sure that the test leads have been clearly moved
away from the circuit under measurement before opening the battery cover of
the meter.
Warning
Do not mix old and new batteries. Do not mix alkaline, standard (carbon-zinc), or
rechargeable (ni-cad, ni-mh, etc) batteries.
• If the sign
appears, it means that the batteries should be replaced.
