4.3 Calibration
Follow the following instructions to calibrate the Insta-Trans Trace
Oxygen Transmitter. Refer to figure 4-1.
1. Select range to be calibrated and enable calibration gas flow.
2. Wait until the display reading is stable before beginning the
span adjustment.
3. Once the reading is stable press COARSE to select the
Coarse mode.
4. Adjust the ‘COARSE’ range up or down using the ▲ and ▼
keys until the display reads the value that is closest to the
calibration gas oxygen concentration level.
5. When set to a value close to the calibration gas concentration
level press FINE to select the Fine mode.
6. Adjust the ‘FINE’ range up or down until the display reads
the value of the calibration gas oxygen concentration level. If
unable to reduce the Fine range lower, proceed to step 7. If
unable to increase the Fine range higher, proceed to step 8.
Else, proceed to step 9.
7. Set the transmitter into ‘COARSE’ mode and adjust the
Coarse range DOWN exactly 4 increments. Then, go back to
step 5.
8. Set the transmitter into ‘COARSE’ mode and adjust the
Coarse range UP exactly 4 increments. Then, go back to step
5.
9. Press RUN to complete calibration.
