key to confirm.
The instrument is so calibrated.
For Redox and Chlorine, calibrate first calibration point by using buffer solution (e.g. 650mV) o by using a
photometer ( CALIBRATE BUFFER for REDOX and CALIBRATE DPD1 for CLORINE ).
Second calibration point (available in EXPERT mode only) is the "ZERO", which is possible to calibrate
by disconnect the probe and shortcutting BNC input connector.
