Choose the type of probe the transmitter 8202 is fitted with before calibrating the sensor.
• In order not to interrupt the process, activate the HOLD function. See chap. „9.9".
• Before each calibration, correctly clean the electrodes with a suitable product.
• In a 2-point calibration, the buffer solutions used must be at the same temperature.
• Set the periodicity of calibrations in the "Interval" function in the sub-menu "Calib interval" (see previous page): each time a calibration
