Emissivity
Most organic materials and painted surfaces have an emissivity of 0.95 (pre-set in the
tester). Inaccurate readings will result from measuring shiny or polished metal surfaces.
To compensate, cover the surface to be measured with masking tape or matt black paint.
Allow time for the tape to reach the same temperature as the material underneath it.
Measure the temperature of the tape or painted surface.
Torch
When the tester is powered on, press the
key to switch the torch on and off.
Volt Sense (non contact voltage detection)
The Volt Sense function is ON automatically when the tester is switched on and is in
standby mode. The LCD displays will display the indicator.
While an electric field is being sensed, the LCD displays flashing “
