SmartReader Data Logger

mouse to find the byte value recorded during the latter part of the minimum two hour test

portion (refer to step 5). Record this as the "bL" reading.

8. Zoom in on the section that relates to the 75% RH level in the test chamber. Again, use

the mouse to find the byte value recorded at the end of the minimum two hour test (refer

to step 5). Record this value as the "bH" reading.

9. Switch to the Setup window in TrendReader software.

10. Use the following equation to calculate the "Low" calibration adjustment value:

Low = (71 x bL - 145 x bH) / 296

11. For the "High" calibration adjustment value use the following equation:

High = 40 x (-74 / (bH - bL) - 1)

12. Now enter the same values by revising the logger file and view the corrected graphs.

13. If the results are satisfactory, save the calibration changes to the logger (remember to set

the RH channel's equation number back to 71).
