Calibration
The CD-6B uses an optional automated background calibration “Abc” to set the clean air level. The CD-6B will
maintain accuracy if it is exposed to the “clean air reference value” (this reference value is the lowest concentration
to which the sensor is exposed) at least once per week.
42T
NOTE:
42T
This applies when used in the typical indoor ambient air with weekly unoccupied periods.
If automated background calibration “Abc” is disabled, manual calibration at regular intervals will be required to
reliably maintain accuracy (See section 7 Testing). The device can be set to issue calibration reminders using the
Calibration Period “CAL” setting (see section 4.8.16).
6.2
Sensor Life Reset
The Sensor Life can be extended only by 1 year, so the sensor life reset option is not available once the extended 1
year is over.
After resetting the sensor life, the unit will still indicate a “t 80” error and will need to be calibrated before it can be
used for the extended 1-year life.
To reset the sensor life,
1.
Remove the Philips screw on the front of the CD-6B. Pull the front cover of the unit off.
2.
From normal mode, press
NEXT
four times. The display will show “SEn” or Sensor Mode.
3.
Press
ENTER
. The display will show “rSt” or Reset Sensor Mode.
4.
Press
ENTER
to see the sensor reset status.
5.
If the sensor life has already been reset, “don” will be displayed. If it has not been reset, “no” will be
displayed. Press
NEXT
to change it to “YES” (flashing).
6.
Press
ENTER
to confirm the change (solid) and press
ENTER
again to return to "rSt” in the “SEn” menu.
7.
Press
NEXT
until “End” is displayed then press
ENTER
to get back to normal operation. The sensor life will be
reset for 1 year.
6.3
Cleaning
Cleaning of the external surfaces is best carried out using a damp cloth with a mild detergent or soap. Use a vacuum
cleaner with a soft brush to remove dust or contamination under the cover. Do not blow out the sensor with
compressed air.
CAUTION
Avoid the use of harsh cleaning materials, abrasives and other organic solvents. Such materials may permanently
scratch the surfaces and damage the display window, labels, sensor or instrument housing. High voltage terminals
(100-240VAC) are located within this detector, presenting a hazard to service technicians. Only qualified technicians
should open the detector case and service the internal circuits. Ensure power is removed from the detector prior to
cleaning the unit.
