Calibration |
| Notes: |
Jaclyn Hatala did a temperature correction calibration for the EC probe on 1/27/11.
1. First, I submerged the probe in water of 25C for 10 minutes and recorded the uncorrected EC values from
the datalogger program MBCR23X_TOWERMET_V100.
2. Next, I submerged the probe in water of 20C for 10 minutes and recorded the uncorrected EC values.
3. I used the formula TC=100 * (C-C_25)/((t-25)*C_25) provided by the Campbell manual to calculate the temperature
correction in %/C. The value I got was 0.786%/C.
4. I changed the MBCR23x_TOWERMET_V100 program to use the uncorrected EC to provide a corrected EC value (Cond_corr). |
