2. Activate “Execute” (Enter/Select) to start calibration.
3. The UD10-DCU will display “Waiting for Zero” on
the main display screen, with a solid red LED on the
PIRECL housing illuminated.
4. The UD10-DCU will then display “Waiting for Gas”
on the screen, while the LED on the PIRECL is
flashing red.
5. Apply calibration gas to the PIRECL
6. The UD10-DCU will display “Waiting for Span” on
the screen, while a red flashing LED on the PIRECL
housing is illuminated.
7. When the UD10-DCU displays “Remove Cal Gas”
on the screen and the LED on the PIRECL housing
is off, remove the calibration gas.
8. After successful calibration, the UD10-DCU
automatically returns to the normal display with the
green LED illuminated on the PIRECL housing.
To initiate calibration from the PIRECL while monitoring
calibration using the UD10-DCU display:
1. Using the magnet, activate the magnetic calibration
switch on the PIRECL detector. See Figure below.
The LED turns from green to red.
