Note:In addition to storing up to 50 gas concentration scales, each scale may be given an identifier of up to ten characters.  Without the correct security code, the programmed confidential concentration factors cannot be altered. Resolution of the gas concentration scale can be user set after entering the calibration factor. A separate security code is required before the resolution can be altered.
