5.3 Calibration Messages
1. If a 1-point calibration has been successfully performed, the WP-81 will
display the following message, and the asymmetry of the sensor. 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 sensor. For
example…
1 Point Cal. Fail
Asy= 1.50pH Hi
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
sensor. For example…
2 Point Cal. OK
Asy= 0.10pH
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 sensor. For example…
2 Point Cal. Fail
Slope=130.0% Hi
2 Point Cal. Fail
Slope= 70.0% Lo
6. mV/ORP Calibration
The mV section is factory calibrated. There is no user-calibration facility
for this mode.
