This command compares the laser signal strength to its original strength. The original strength is the signal level the laser had when the 84 ___________________________________________________________________M210862EN-A Chapter 5 ________________________________________________________________ Operation factory calibration was made. With this command it is possible to measure contamination of the optics. Syntax: SIL<cr> Example: >sil Signal level is 100% compared to signal level at factory Signal Level Display Function (Sil) When the signal level display function Sil is selected the laser signal strength is compared to its original strength (displayed as 0 . . . The original strength is the signal level the laser had when the factory calibration was made. With this function it is possible to measure contamination of the optics. 0511-076 0511-077 Show Statistical Information Command (STATS) This command displays statistical information.

Syntax: SAVE<cr> Example: >save EEPROM EEPROM EEPROM EEPROM (basic) saved successfully (op) saved successfully (op_log1) saved successfully (op_log2) saved successfully VAISALA _______________________________________________________________________ 87 User's Guide ______________________________________________________________________ Resetting the Transmitter Reset Command (RESET) This command resets the transmitter. This command has exactly the same effect as toggling power to the transmitter. Syntax: RESET<cr> Example: >reset Reseting. . . OMT300 - Version STD 1. 02 Vaisala Oyj, 2004-2005 . . . Reset Function (Off) When the reset function Off is selected the transmitter stops all operations and performs a reset. To reset the transmitter, select function Off from the menu and press Ent. New measurement starts after the self-test is completed and the oxygen absorption line is found. 0511-106 0511-107 88 ___________________________________________________________________M210862EN-A Chapter 6 _____________________________________________ Setting Environmental Parameters CHAPTER 6 SETTING ENVIRONMENTAL PARAMETERS Environmental Parameter Compensations The oxygen measurement of OMT364 is somewhat affected by the temperature, pressure and background gas of the measuring environment. Because of these phenomena, OMT364 has built-in compensations for the temperature and pressure of the operating environment as well as for the water and CO2 content of the background gas. To achieve the most accurate measurement, the compensations should be enabled. The compensated output corresponds to "% O2" in the actual environment (T, P, humidity, and CO2).
