Fig. 2.3.1 – Display
1.
Symbol – displayed during set-up of instrument parameters.
2.
Primary display – 4½ digit. Provides direct readout in pH and millivolts of samples and
standards.
3.
Mode annunciators – shows selected measurement mode; pH, mV (Absolute and Relative).
4.
Calibration point – shows 1, 2 or 3 point symbol depending on level of calibration selected by
the user.
5.
Buffer selection – indicates whether the instrument is using manually entered or automatic
selection buffers. Will show which type of buffer is being used.
6.
Endpoint symbol – this symbol is displayed when the pH changes by less than 0.005pH
(0.2mV) over a five second period. Once an endpoint has been detected the reading must
change by more than 0.005pH (0.2mV) to clear the endpoint symbol.
7.
Secondary display – 6 digit display. Provides direct readout of automatic or manual
temperature. Scrolls and displays selected parameter information in set-up mode.
8.
Mode annunciators – indicates temperature in °C or °F and whether the measurements are
manually or automatically temperature compensated.
9.
Status display – 2½ digit. Provides information relating to electrode slope value, mV Eo value
at calibration and memory result number.
10. Mode tags – Each mode tag is highlighted when selected; SETUP, MODE or RESULTS.
