Choose three buffers (cal 1, cal 2, cal 3)
from the set for calibration. For ease of use,
set the buffers in the order that you will use
them.

You can select one of four preset slope
values for 1 point calibrations (c = 1, c = 2,
c = 3, c = 4). If you are not sure of your
electrode type, or wish to do 2- (3, 4, 5)
point calibrations, do not select a slope as
the 315 will calculate the slope and use this
value rather than the factory setting.

You can enter the isopotential point (in mV)
of your electrode. The range is –99 to
+99 mV. The 315 has a preset isopotential
point of 0 mV. Change the isopotential
point using
the value and move on.
You can set five concentration standards to
values of your choice, the range is 0.001 to
19999. For ease of use, set the standards in
cal 1 to
the order that you will use them. Set the
