It is possible to execute calibration by adjustment of the potentiometer located on the side of the SMART BLOCK, as
described below. This process is reserved for the users without access to the software and with time constraints which
require immediate use of the instrument. Since the potentiometer adjustment changes the calibration settings but does not
update the information in memory in the SMART BLOCK, both features and accuracy may be affected. Such a SMART
BLOCK should be returned to an authorized repair depot for recalibration with the software as soon as practical.
- execute an auto zero turn-on in a clean area
- open the SMART BLOCK cover
- place the standard gas nozzle in contact with the SMART BLOCK
- regulate the output at 1 liter per minute
- wait for stabilization of the display
– adjust the potentiometer to make the displayed value correspond with the known concentration of the gas.
