If the span value of the selected range is 0 (see section 5.6.1), then it willnot be calibrated. If one range is calibrated and the span value for the lower rangesis zero, calibration parameters will be copied to this range. To calibrate all rangeswith the same span gas, you must enter the gas concentration in the Span GasCalibration screen for ALL RANGES. You must also calibrate each range. Offsetsand scalors are NOT copied to other ranges.Auto Calibration Screen7.4.2. F2 Manual CalibrationFrom the Calibration screen, F2 starts manual calibration. If auto range is selected,calibration is not possible, and the appropriate range can be selected. In the manualcalibrations menu, three options are possible:F1 Flow zero gasF2 Flow span gasF3 Range selectManual Calibration Screen
