MDS E-SCAN MPR E-SCAN OPERATION
15
2.2 Normal Mode
2.2.1 What Normal Mode Does
In normal mode the system displays the following information:
• Name of the current product being measured along with an associated unit number.
• Software version number.
• Current time and date.
• On-line SOLIDS measurement.
• On-line temperature in Degrees Fahrenheit and Centigrade.
• Alarm points for measurement.
• Error status for system measurement, communication and voltage levels.
• Graphics menu to allow access to other MPR E-Scan system features.
Note: In normal mode set points cannot be changed or adjustments made.
2.2.2 System Indicators
C Isolation valve is closed. The MPR E-Scan will not initiate a prism clean.
T Below temperature compensation range. No prism clean allowed. Temperature at least
10 degrees C below set temperature.
H Measurement Hold. Current readings and analog outputs are maintained until complete.
Indicates a cleaning cycle is in progress by a purge message, as well as a current
measurement voltage display while in normal mode.
P Purge failed. This means the previous purge cycle did not properly clean the prism.
O Measurement over range. Current reading above last calibration point for MPR E-Scan
in the calibration table.
U Measurement under range. Current reading below first calibration point for MPR E-Scan
in the calibration table.
S Measurement sample reading has been recorded as the reference for Analog Zero
adjustment.
