CHAPTER 6. CALIBRATION
IMPORTANT:
Before performing any calibration procedure ensure
that new 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.
6.1. 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 instrument’s calibration screen via the
keypad, or with the Fyrite
®
User Software.
Benefits of the B-Smart
®
Sensors include the following:
•
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 (see Service Centers on page 99) every 6 months to 1 year to assure that
the analyzer continues to meet its published accuracy specifications. B-Smart
®
sensors, however, can be calibrated in the field if your facility has the necessary
equipment and qualified personnel to perform the procedures described in the
following sections.
6.2. Starting a Calibration
Start any calibration procedure by doing the following.
1. Place the probe in an area of fresh air, turn ON the analyzer, allowing it
to cycle through its 60 second warm-up period. During warm-up, the
analyzer’s operation is checked and the sensors are set to the following
ambient conditions:
•
Oxygen sensor spanned to 20.9%
•
All gas sensors are zeroed
•
The pressure sensor is zeroed
2. Any errors detected during warm-up will be listed on the display
immediately following warm-up. Correct any errors before proceeding.
Refer to page 93 (Error Messages) for a listing of error messages and
their meaning.
3. Display the MAIN MENU by pressing the
MENU (F2)
button. If
necessary, press
ESC
until MENU appears above
F2
.
4. Use the ▲▼ buttons to highlight CALIBRATION, and then press
ENT
to
display the CALIBRATION PASSWORD screen.
