Calibration process for TS21I_ELE_O2
TS21I_ELE_O2 needs to be calibrated once in year from support or installation team. For
calibration, it requires calibrated gas cylinder
The connectors in the circuit associated with calibration process are shown as below.
Ensure that sensor is properly connected on RASS_4124 CON1.

Process Steps
1.
IPZC
(Input Zero Calibration)
This is a calibration function used
to calibrate sensor in clean air. It
displays raw sensor data on
seven segment display.
1.
Preheat the sensor for minimum 15 minutes.
2.
Go to menu
IPZC
.
3.
Note down the count in clean air. Press
ENTER
key
to save the setting.
4.
Press
ESCAPE
key to exit from configuration mode
and remain in Idle or Scan mode.
2.
19.5
(19.5 % vol calibration)
This is a calibration function used
to calibrate sensor for 19.5 %
vol gas. This menu must be used
only when the unit is in clean
atmosphere. It displays sensor
data on seven segment display.
1.
Go to menu
19.5
.
2.
Use 19.5 % vol concentration calibration gas
cylinder and give gas to the sensor.
3.
Note down the count.
4.
Press
ENTER
key to save calibration.
Note
: Do not stop giving gas to sensor until settings
are saved.
5.
Press
ESCAPE
key to exit from configuration mode
and remain in Idle or Scan mode.
