Mounting A New No-Sensor - Bosch BEA 150 Repair Instructions

4.12.4

Mounting a new NO-Sensor

Zero calibration is performed.
Allow calibrating gas to flow through the
BEA in line with the instructions on
screen.
Open the Test-gas bottle sufficiently to
allow some Test gas to continually flow
out through the rotameter, even with the
pump running (pressure-less calibration).
i The NO measuring sensor is very
sluggish. An "advance flow" through
the NO measuring sensor is therefore
necessary.
After this flow, confirm with E or by
clicking OK.
Assessment is performed. The remaining
flow time is displayed.
After calibrating gas has flown through
the BEA, the measured NO value, the
corresponding test current and the date of
calibration are displayed.
To end calibration of the NO measuring
sensor, confirm No by pressing E or
clicking on No.
You will now return to the NO-Sensor
menu, and the timer for the adjustment
interval is started.
