7.5 Calibrate Optima Plus
OELD mobile app allows a user to calibrate the Optima Plus same as SHC1 handheld device.
1. After connecting to OELD device, go to Calibrate menu on the mobile app
2. Click on "Zero" button to start zeroing
3. Mobile app will initiate zero calibration after inhibiting the 4-20mA output of the Optima Plus
4. After successful zeroing, click on "Span" button to perform span calibration
5. Apply calibration gas to the Optima Plus
6. Wait until span calibration is complete
Refer to Optima Plus User's manual prior to carrying out gas calibration
Caution: Searchpoint Optima Plus is factory calibrated and does not require routine calibra-
tion. In most cases, a re-zero will correct any inaccuracy in the gas reading. It is strongly rec-
ommended that a span calibration is not carried out
As some calibration gases may be hazardous, ensure that outlets from gassing accesso-
ries exhaust safely.
A compressed air cylinder (20.9%Vol oxygen) should be used to perform the zero
calibration if the area where the detector is located contains any residual amount
of the target gas.
