The Alnor Model AXD620/A
IRFLOW PVM620 can also be recalibrated in
the field using the CALIBRATION menu. These field adjustments are
intended to make minor changes in calibration to match a user's calibration
standards. The field adjustment is NOT intended as a complete calibration
capability. For complete, multiple-point calibration and certification, the
instrument must be returned to the factory.
Cases
If the instrument case or storage case needs cleaning, wipe it off with a soft
cloth and isopropyl alcohol or a mild detergent. Never immerse the Alnor
Model AXD620/A
IRFLOW PVM620. If the enclosure of the Alnor Model
AXD620/A
IRFLOW PVM620 or the AC adapter becomes broken, it must be
replaced immediately to prevent access to hazardous voltage.
Storage
Remove the batteries when storing the unit for more than one month to
prevent damage due to battery leakage.
