IMPORTANT: Before performing any calibration procedure
ensure that fresh batteries are installed or use the optional
AC power adapter. Also ensure that the analyzer is at room
temperature and will be sampling fresh air when turned
ON.
5.1 B-Smart Sensors
The PCA
®
3 uses Bacharach’s B-Smart
®
Sensor technology for CO
Low
,
CO
High
, NO, NO
2
, and SO
2
. The B-Smart
®
Sensor is marked with a 10 or 14
digit calibration code that can be entered in the instruments calibration
screen via the keypad, or with the Fyrite
®
User Software.
Benefi ts of the B-Smart
®
Sensors:
• New sensors can be installed without applying gas for calibration.
• Sensors can be pre-calibrated and installed when needed
• Sensors can be moved from one analyzer to another.
• The analyzer’s diagnostics screen shows what sensors are
installed, and their current end-of-life condition (Good, Low, Bad).
B-Smart
®
sensors should be calibrated by an authorized Bacharach
Service Center (Section 8.3) every 6 months to 1 year to assure that the
analyzer continues to meet its published accuracy specifi cations. B-Smart
®
sensors, however, can be calibrated in the fi eld if your facility has the
necessary equipment and qualifi ed personnel to perform the procedures
described in the following sections of this instruction manual.
