Conditions:
¨Before you start the linearization you have to calibrate the largest range of the channel (usually range 4) with zero gas and span gas.
¨You have to record a raw values/setpoint values table to linearize a channel. You need minimum 6 raw values and their corresponding setpoint values: zero, end of range and 4 intermediate values. You should take 10 to 15 values (maximum: 30) to improve the precision of the linearization curve.
Realize the linearization:
1)Disable the linearization:
·Before you record the linearization values you have to disable the current linearization to avoid the influence from the old values to the calculation of the new curve.
·Change to the line "Linearizer is" with the −
·Press the 8
·Confirm your adjustment with the 8
2)Zero and span gas calibration:
·Calibrate the largest range (usually: range 4) with zero and span gas.
·The method is described in 4.5 p.
3)Recording the raw values/setpoint values table:
·If you have a defined gas flow, you can read each raw value in any menu display at the top right or in the single component display.
·Example:
You have got the following values for the
No. | Setpoint Value | Raw Value |
| [ppm NO] | [ppm NO] |
1 | 0.000 | 0.000 |
2 | 217.455 | 266.291 |
3 | 319.620 | 387.709 |
4 | 428.610 | 517.464 |
5 | 536.760 | 645.199 |
6 | 636.510 | 757.313 |
7 | 955.395 | 1113.910 |
8 | 2105.560 | 2263.390 |
9 | 3163.860 | 3163.860 |
4)Putting the table values into the corresponding menus:
·Change to the menu line "Linearization raw values..." or "Linearization setpoint values..." with the −
·Press the 8
·Select the first number with the 8
·Put in the first raw/setpoint value of the table:
·Select any digit with the ←
