Non-contact IR Surface Temperature Measurements
The built-in IR sensor can remotely measure the temperature of just about any surface. The Laser
pointer allows the user to aim accurately when taking remote measurements.
1. Turn ON the meter using the on-off button.
2. The IR sensor is located at the top of the meter.
3. Point the sensor toward the surface to be measured.
4. Press and hold the IRT button to begin measuring the surface
temperature of a desired target.
IR TEMP
and
will appear on
the display. The laser pointer will switch on to help aim the meter.
5. The measured IR surface temperature will appear on the LCD.
The temperature displayed is the temperature of the area within
the spot.
6. When the IRT button is released, the laser pointer will switch off
and the reading will freeze (data hold) on the display for
approximately 7 seconds.
7. After the 7 second hold time the meter returns to the Air
Velocity/Flow and Air Temperature mode.
WARNING: Do not directly view or direct the laser pointer at an eye.
Low power visible lasers
do not normally present a hazard, but may present some potential for hazard if viewed directly for
extended periods of time.
Data Hold
1. The HOLD button in the upper keypad area freezes the displayed vane
