Keypad functionsThe large membrane keypad makes the instrument easy touse. Each button, when pressed, has a correspondinggraphic indicator on the display. While in the measurementfunction, the primary display shows the readings for pH, rel-ative mV, mV and Ion Concentration. The secondary displayshows the temperature readings simultaneously with theprimary display (Figure 1)NOTE: The secondary display shows “Ion”(not tempera-ture) in Ion concentration mode.The meter also has primary and secondary functions.To perform primary functions, press the appropriate func-tion key. During operation, the meter assumes the primaryfunctions are active.To perform secondary functions, press SHIFT first, andthen the appropriate function key.ON/OFFPrimary function: Powers the meter on or off. The meteralways starts-up in the pH measure (MEAS) mode. Whenthe meter is OFF, the display shows current time wheneverthe AC adapter is plugged in.Secondary function: None.Numeric value: None.SHIFTPrimary function: Press to perform secondary functions.Secondary function: None.Numeric value: None.CAL/MEASPrimary function: Press to toggle between the calibrationmodes and measure functions. Also, exit from the setupmode and secondary functions.Secondary function: None.Numeric value: None.MEASpH°CpHNumeric key valuesSome keys also have numeric values. Donot press SHIFT to enter numeric values.The instrument knows when to entera numeric value (for calibration, settingtemperature, etc.). and when to activatea primary or secondary function.
