weight in the selected unit is displayed.
6. Place the calibration weight on the platform and press
ON/ZERO Off button. The display will again show "-C-".
7. After span capture, the display will return to the normal
weighing mode.
NOTE: The message "CAL E" will appear if an incorrect calibration weight
was applied. Repeat the procedure using the correct calibration weight.
Calibration Locking: By use of an internal switch, the calibration function may be
locked (disabled), and unauthorized recalibration prevented.
1. With the scale powered off, remove the back housing section of the indicator
by unscrewing the four screws at the bottom.
2. Slide the switch on the PCB (marked SW3) to the position marked "CAL LOCK".
3. Reassemble the housing.
4. If required, place tamper evident sealing labels over the screw holes or over
the housing edges.
If later recalibration is required, the housing will need to be reopened and the lock
switch returned to the original position.
NOTE: When the lock switch is set to the CAL LOCK position, the power-on zero
range is reduced to 10% of full capacity.
