| Help: | CAL_TEMP temperature value is used in the temperature compensation algorithm during a two-point pH calibration.TWO-POINT calibration procedure: 1. For PRIMARY VALUE TYPE=pH write the two-point calibration temperature into CAL_TEMP. Send the value to the instrument. (For ORP and pION this step is not necessary.)2. Apply low point calibration input. Observe PRIMARY VALUE and make sure it is stable. Write the desired calibration value into CAL_POINT_LO.3. Apply high point calibration input. Observe PRIMARY VALUE and make sure it is stable. Write the desired calibration value into CAL_POINT_HI.4. Any calibration errors will be available in EXTENDED STATUS. |
