When you press cal the pH buffer or concentration
standard you selected for cal 1 (Program Menu) is
displayed for 2 seconds, and then the 315 starts
measuring. If you want to use another pH buffer
(choice of 3) or conc. standard (choice of 5) press cal
again. Press cal repeatedly to exit calibration routine.
The decimal point flashes during cal measurement.
When the electrode output has stabilized
the stability indicator appears.
Manual endpoint - press read to endpoint
Auto endpoint - the 315 automatically endpoints.
When a calibration has endpointed you can press
mode to display the absolute mV value and
temperature of the buffer or standard; the display
reverts to the buffer or standard and E
values, or the buffer or standard and slope values
for a 2-(3, 4, 5) point calibration after 2 seconds.

If you press mode to select pH, mV or concentration
the 315 begins measuring immediately, and you will
not need to press read to start the sample
measurement.
