Conair GB - Manual (Page 46)

recalibration does not take place. The unit functions like
a volumetric feeder without checking or correcting for
errors. Since load cell readings are ignored, this flag
allows operation even if the load cells become damaged.
Dispense times will be based entirely on the WT and TI
parameters.
*88 Press (*,8,8) to force a printout of the display on the
controller front. DATE, TIME, Machine number, and display
will print:
Date: 11/09/93
Time: 17:22:01
Machine number: 002
Display Readout: P 500.0
This is useful for obtaining printed verification of load
cell accuracy for ISO-9000 and British Standards rules.
The recommended procedure is:
1. Place the unit into the Program mode.
2. Press *88 for printout of empty bin TARE weight.
3. Place a KNOWN CERTIFIED WEIGHT into the weight bin.
4. Press *88 again for printout with the weight added.
5. The different between the two weight printouts should
equal the KNOWN CERTIFIED WEIGHT.
*89 Press (*,8,9) to select the desired weight unit (GRAMS,
KILOGRAMS, OUNCES, POUNDS) for readout of data. For the
U.S.A. systems are supplied with POUND readout selected.
KILOGRAMS is preferred for nearly all countries outside the
U.S.A. GRAM or OUNCE readout are appropriate only for very
short runs or short demonstrations.
Use the * key to walk through the four possible selections.
Press EXIT when the weight unit you want is displayed.
*98 Press (*,9,8) to set flag for RAW-SIGNAL readout in place
of gram readout of scale weight. Power-On will always set
this flag to OFF. Use the * key to toggle flag ON or OFF.
Press EXIT when done. A raw signal readout is useful to
demonstrate the extreme sensitivity of the load cells. The
raw signal readout bypasses the calibration math routine.
Load cell function can be monitored without concern for any
improper weight calibration that may have been done.
These functions were explained previously in the MANUAL MODE section:
*00 Press (*,0,0) to CLEAR ALL DATA fields.
*99 Press (*,9,9) to set flag to enable Weight Calibration of
the Load Cells.
