Span adjustment
Notes:
CO calibration gas is toxic, never inhale the gas!
Symptoms: Dizziness, headache and nausea.
Procedure if exposed: Bring into fresh air at once, consult doctor.
•
Connect calibration adapter to the sensor element.
•
Apply sensor element span calibration gas (200 ppm CO), (150 ml/min; 14.5 psi ± 10%).
•
Wait two minutes until the signal is stable, adjust signal with span potentiometer ”Gain” until the signal
reads the appropriate mVDC (± 3 mV, see calculation for control voltage 5.2) and is stable.
•
Remove calibration adapter with a careful light turn. Inspect the seating of the sensor element!
5.2 Control span voltage calculation
160 (mV) x test gas concentration (ppm) + 40 (mV)
Measuring range CO (ppm)
Example
Measuring range CO concentration
250 ppm
Test gas concentration
200 ppm
Control voltage
168 mV
160 (mV) x 200 (ppm) + 40 (mV) = 168 mV
250 (ppm)
