Note (for Thermal Sensors only)
For best results with thermal sensors, it may be
necessary to do the procedure once with the sensor
disconnected then afterwards again with the sensor
connected.
After completing steps 1 - 4 above, Connect the sensor
and make sure it is at room temperature and well
shielded from any stray thermal power. It may be best
advised to lay the sensor with the absorber face down on
the table.

sensor connected.

wait for message, "ZEROING COMPLETED".

mode and press the Enter key.
Note: For Pyroelectric Sensors
In addition to zeroing the meter as described in section
3.5.5, it is important to zero the meter against the sensor
you are using the first time. Please see section 2.5.1 on
how to do this.

3.6 Hardware Functions

3.6.1. Backlights
3.6.1.1. LCD Backlight
The LCD backlight is actually a set of LED's that illuminate
the display from behind. Because the Vega uses a color
display, the backlight must be constantly on. It can be
operated at full or half intensity (to conserve power
consumption). The Vega can also be configured to allow
toggling of the backlight level with the on/off switch.
The Vega backlight consumes considerably less power
than competing instruments and therefore it can operate
from the battery even when the charger is not plugged in.
