1. If a 1-point calibration has been successfully performed, the WP-81 will
display the following message, and the asymmetry of the electrode.
For example…
1 Point Cal. OK
Asy= 0.10pH
2. If a 1-point calibration has failed, the WP-81 will display the following
message, and the failed asymmetry value of the electrode. For
example…
1 Point Cal. Fail
Asy= 1.50pH Hi
or :
1 Point Cal. Fail
Asy= -1.50pH Lo
3. If a 2-point calibration has been successfully performed, the WP-81 will
display the following message, and the asymmetry and slope of the
electrode. For example…
2 Point Cal. OK
Asy= 0.10pH
then :
2 Point Cal. OK
Slope=100.0%
4. If a 2-point calibration has failed, the WP-81 will display the following
message, and the failed slope value of the electrode. For example…
2 Point Cal. Fail
Slope=130.0% Hi
or :
2 Point Cal. Fail
Slope= 70.0% Lo
7. mV Calibration
The mV section is factory calibrated. There is no user-calibration facility
for this mode.
