4 Electronic
flowmeter
calibration
(factory)
Calibrate the electronic
flowmeter board.
1. The electronic flowmeter board is
replaced.
2. The throttling device of the electronic
flowmeter is replaced.
3. The deviation between the measured
value of the electronic flowmeter and that
of the standard flow measurement device
exceeds more than 10% of the reading or
0.5 L/min, whichever is greater.
5 Pressure and flow
zeroing (factory)
Calibrate the deviation
from zero point of the
monitor board and
auxiliary monitor board.
Flow or Paw waveforms deviates from the
baseline.
6 Electronic
flowmeter zeroing
(factory)
Calibrate the deviation
from zero point of the
electronic flowmeter
board.
The electronic flowmeter has a zero point
error. The electronic flowmeter still
displays flow when fresh gases are all
turned off.
7 O2 sensor
calibration (user)
Calibrate the accuracy of
O2 sensor at 21% and
100% O2.
1. The measured value of the O2 sensor
has a great deviation. The deviation
exceeds 3% both in Air and pure O2.
2. The O2 sensor is replaced.
3. The monitor board is replaced.
8 CO2 calibration
(factory)
Calibrate to cause the
module to work more
accurately.
The measurement deviation of the module
exceeds the specified accuracy range.
9 AG calibration
(factory)
Calibrate to cause the
module to work more
accurately.
The measurement deviation of the module
exceeds the specified accuracy range.
10 O2 module
calibration
(factory)
Calibrate to cause the
module to work more
accurately.
1. The measurement deviation of the
module exceeds the specified accuracy
range.
2. The O2 module is replaced.
