Range Calibration Parameters (P650 to P654)
.
P341 (V) RUN TIME
View the accumulated number of days this XPL Plus has been operating, since
the Date of Manufacture (P340).
This value is stored in EEPROM and updated once each day. Therefore, if the
XPL Plus is powered down at least once every 24 hour period, this value will
always be less than 1.
values: 0.000 to 9999
P342 (V) START UPS
View the accumulated number of times power has been applied to the XPL Plus
(following a power interruption), since the Date Of Manufacture.
values: 1 to 9999
P650 OFFSET CALIBRATION
Use this feature if the Empty (P006) value was estimated or if the reported
material level is consistently high or low by a fixed amount (e.g. 2 cm).
Before using this feature, verify the
a) Empty (P006) value (as measured or estimated) was entered correctly.
b) Vessel atmosphere Temperature (P664) is correct.
c) Offset Reading (P062) value (if used) was entered correctly.
To perform an Offset Calibration:
With the material at a high steady level...
1. Press to display the calculated distance*.
2. Repeat step 1 at least 5 times to overcome Echo Lock (P721) and verify
repeatability.
3. Measure the actual distance* (e.g. with a tape measure).
4. Enter the actual value. (The Offset Correction amount is stored in P652).
values: -999 to 9999
