CORRECTIVE ACTION IF THE VERIFICATION FAILS
If the verification does not meet the acceptance criteria defined in section 3, then the following steps can be
taken to correct the calibration of PR-01-S.
1 Check that the prism is in good condition:
See Section 6.7 for more details of prism mounting and dismounting.
2
The following values and diagnostics should be checked from the Indicating transmitter displays
with the standard R.I. liquid on the prism.
Display Key-in sequence
from Normal
Display Value to be
checked Acceptable value
Raw sensor data C-A LED below 200
Image diagnostics C-A-A-A-A Max intensity OK Yes
Endpoint below
75%
Yes
Image below corner Yes
Slope OK Yes
Left curve OK Yes
Right curve OK Yes
If the above checks 1 and 2 fail, please contact K-Patents or your local K-Patents representative for
corrective action.
3 If the above check criteria are met, the instrument can be calibrated. Calibration is done with
minimum five, preferably seven, standard R.I. liquids as follows:
3.1 Mount the sensor on the service bench.
3.2 Take certified standard R.I. liquids. The middle value should correspond to the middle value
indicated in the Final test -section of the latest Delivery data sheet or Standard calibration sheet of
the PR-01-S. Then take 2-3 values above and below this middle value.
3.3 Record R.I. value and corresponding Test and Temperature values from the Normal display.
3.4 Send the value table to K-Patents or to the K-Patents local representative.
3.5 K-Patents calculates new calibration parameters for R.I. measurement.
3.6 Key in the new parameters (soft keys C-B-6-1/2/3/4) and then repeat the verification check as
described above.
