Press CAL if you want to change a parameter value. The selected parameter will start blinking. Press RANGE ( for HI 2212) to toggle between displayed parameters. Press the ARROW keys to increase or decrease the displayed value. Press CFM to save the modified value or CAL to escape. EXPIRED CALIBRATION ALARM Press CAL when the calibration time-out is displayed. Calibration time-out ("OFF" or "1" to "7" days) and "CFM" will start blinking. Press the ARROW keys to change the calibration time-out value. Press CFM to save the modified calibration time-out value. FIRST CUSTOM BUFFER Press CAL when "cb1" is displayed. The custom buffer (disabled ­ "no" or "0" to "16" pH) and "CFM" will start blinking. Press the ARROW keys to change the custom buffer value.
