CF 146 12 V- Rev. 1.0 - 003R-620-100
8.0 ERROR MESSAGES
8.1 Weighing Errors
•
Check Setup = This item can be checked on site by service personnel.
Error Description Resolution
(U - - - - -) The weight is below the minimum allowable weight reading. Increase the weight or decrease
the minimum allowable weight
reading.
(O - - - - -) The weight is above the maximum allowable weight reading.
Warning – overloading may damage mechanical scale elements.
Check the condition of load cell
connections. Check for
damaged load cell.
(ZERO)
(ERROR) The weight reading is beyond the limit set for Zero operation. The
operation of the <ZERO> key is limited in the setup during
installation. The indicator cannot be Zeroed at this weight. Increase the Zero Range
(Z.RANGE) or use the <TARE>
key instead.
(STABLE)
(ERROR) Scale motion has prevented a <ZERO>, <TARE> or <PRINT>
operation from occurring on command. Try the operation again once the
scale is stable.
8.2 Setup and Calibration Errors
Error Description Resolution
The instrument may be in Safe Setup
and an item that needs Full Setup has
been selected for editing. Access Full Setup to edit the item. (ENTRY)
(DENIED)
When accessing setup, more than
three attempts have been made with
the incorrect passcode. Turn the instrument off. When the instrument is turned back
on, enter the correct passcode to access setup.
(LIN.PT)
(LO) An attempt has been made to place a
linearization point below zero. Incorrect linearization point entered (must be between zero
and full scale).
(PT.TOO)
(CLOSE) An attempt has been made to place a
calibration point too close to an
existing calibration point. Re-enter the calibration point. Points must be spaced by at
least 2% of full scale from each other.
(RES)
(LO) The scale build is configured for less
than 100 graduations. Check the resolution (countby) and capacity settings.
(RES)
(HIGH) The scale build is configured for more
than 30,000 graduations. Check the resolution (countby) and capacity settings.
(SPAN)
(LO) The load cell signal range (span) is too
small for these settings. Incorrect span weight entered (must be between zero and
full scale). Scale wiring incorrect. Wrong load cell capacity
(too large). Wrong or no calibration weight added to scale.
(SPAN)
(HI) The load cell signal range (span) is too
large for these settings. Incorrect span weight entered (must be between zero and
full scale). Scale wiring incorrect. Load cell capacity too small
for application.
(ZERO)
(LO) An attempt has been made to calibrate
zero below -2mV/V. Scale wiring incorrect.
(ZERO)
(HI) An attempt has been made to calibrate
zero above +2mV/V. Remove all weight from scale. Scale wiring incorrect.
8.3 Diagnostic Errors
•
Check: This item can be checked on site by service personnel.
•
Return for Service: The instrument must be returned to Cooper Instruments for factory service.
