4. Press
to enter P3.1, the LCD displays one of four available slope
values; P3.1, P3.2, P3.3, P3.4. If the value is less than 75% or more than
115%, change the probe immediately.
5. Press
to enter P3.2, P3.3, and P3.4.
Note...
The solution range differs between NIST and Custom buffers.
6. Press
to enter P3.5 and view the offset value. The offset value
is the mV value of pH 7 (default 0.0). The offset value will be different
after calibration. If the value is outside the range of ± 60 mV, replace
the probe.
