ACCURACY TEST
The instrument can be tested with the test kit comprising of:
-
The 10ppm cylinder
-
Flow regulator 1l/min.
Service and Calibration
The LASER ONE should be regularly serviced. QED recommends that the instrument is calibrated on
an annual basis.
NOTE: The next calibration date can be seen during the warm up sequence after powering the
instrument and also on a label on the underside adjacent to the battery charging connector.
The hydrophobic internal filter should be checked periodically, (typically this will be weekly during
periods of heavy use).
Unlock the filter by turning it
counterclockwise and remove it.
Change the filter and reassemble by turning
it clockwise.
