¨Example:
·Range from 0 to 1000 ppm
·0% value shall be 400 ppm, 100% value shall be 700 ppm
· Analog output is normally: | 0V | = 0 ppm | 10V | = 1000 ppm |
· After changing the output signal: | 0V | = 400 ppm | 10V | = 700 ppm |
¨Change to the line "Signal value for 0% output" or "Signal value for 100% output" with the ↓
¨Select the value with the ENTER key or the →
¨Select any digit with the ←
Note:
If you change the measurement range the adjustment done in this menu will disappear and go back to the standard values of the range! To change the output signal values permanently, you have to change the adjustments in the menu "Range Settings"!
The signal range at the analog output should not be less than the littlest measurement range. Otherwise, it is possible that the noise level will be very high at the analog output!
5) Determination of the output current range:
¨Select to the line "Output current range" with the ↓
¨Press the ENTER key or the →
¨Confirm the new adjustment with the ENTER key.
Options: 0...20 mA (and automatically 0...10V) or 4...20 mA (2...10V).
6) Analog output during calibration:
In the line "Hold output during calibration?" you can determine the signal drift of the analog output and of the limits during calibration:
¨Yes: During the whole calibration the analog output signal and the status of the limits are fixed to the last value before calibration.
¨No: The analog output signal and the status of the limits are following to the measurement signal during the whole calibration procedure.
Sample Gas | Zeroing | Spanning | Sample Gas |
Hold output during calibration? No
0V | xV |
Hold output during calibration? Yes
Note:
¨The adjustments "Yes/No" are valid for all kinds of calibrations of a platform SIO or MLT analyzer SIO: manual, time controlled, AK controlled and system calibration.
