3.2 Preparing the dry-block calibrator
The ATC-B-version has a precision reference input. To achieve the
high precision, a set of sensor coefficients relating to the specific
sensor must be present in the ATC. Before use of the ATC, ensure that
the correct coefficients in the ATC are equal to those from the sensors
calibration certificate. This is done with the PC software JOFRACAL
included on the CD. Please read how to do in the chapter “Reference
Sensors” in the JOFRACAL user manual on the CD.
Warning
The calibrator must not be used for any purposes other
than those described in this manual.
The calibrator has been designed for interior use only
and should not be used in hazardous areas, where
vapour or gas leaks, etc. may constitute a danger of
explosion.
The calibrator must be kept free within an area of 20
cm on all sides and 1 metre above the calibrator.
The ATC-125 contains the gases R-1270 and R-704
under pressure. The calibrator must under no
conditions be stored or operated at ambient
temperatures above 60C (140F). Doing so may cause
a hazard.
Note…
The instrument must not be exposed to draughts.
