Set up parameters:

¨Press the ENTER key or the → -key in the line "Zero offset" to select the parameter and set up "32700" resp. "524000" with the − -key or the ↓ -key. You may select any digit with the → -key or the ← -key.

Note: The zero offset is about 32000 counts for the CLD software revision 2.2.1 (16 bit D/A transformer) and about 520000 counts for the revision 2.3 (20 bit D/A transformer).

¨Confirm your setup with the ENTER key.

¨Go to the line "Span factor" with the ↓ -key.

¨Press the ENTER key or the → -key to select the parameter and set up "0.00015" with the arrow keys.

¨Confirm your setup with the ENTER key.

Notes:

¨You have to set up the factors for all ranges.

¨With the parameter "Zero offset" you will fix the zero value. The changing of the zero offset will influence the signal immediately (look at the headline).

¨With the parameter "Span factor" you will fix the signal at the span gas setpoint. The changing of the span factor will influence the signal immediately (look at the headline).

¨Conditions for the manual input of factors:

·"Disabled" has to be set up in the line "Calibration adjustment limits" of the menu "Zero/span calibration".

·"SEPARATELY" has to be set up in the lines "Zero ranges" and "Span ranges" of the menu "Calibration Parameters" (see 5.1.2, p. 5-9).

¨Attention:

After the calibration with factors you have to calibrate with zero gas and span gas in the usual way!
