CD-11 Indicator

3. CALIBRATION AND SEALING

Model CD-11 Indicator requires span calibration before using. Span calibration ensures that the Indicator
reads correctly within specifications. For best results, calibrate at or near full capacity. Calibration unit can be
set to either kg or lb.
NOTE: When the Indicator is used in Legal for Trade or legally controlled applications, the calibration
menu is locked out and is not accessible. This is to prevent unauthorized personnel from changing calibra-
tion.
Before beginning calibration, make sure masses are available. If you begin calibration and realize calibration
masses are not available, exit the menu. The Indicator will retain previously stored calibration data. Calibra-
tion should be performed as necessary to ensure accurate weighing. Masses required to perform the proce-
dures should be in compliance with the requirements of the scale base being used with the Indicator.
You have a choice of either span or linearity calibration. Span calibration checks zero and full span calibra-
tion points. Linearity calibration checks zero, mid span and full span points.
Procedure

SPAN CALIBRATION

With the Indicator ON, press and hold the G/N/T/ Menu button until MEnU is
displayed. When the G/N/T/ Menu button is released, CAL is displayed.
Press the G/N/T/ Menu button, SPAN Y is displayed.
Press the G/N/T/ Menu button, -C- is displayed. The scale base MUST be stable
during this period as it establishes a zero point. After a few seconds, the
requested weight value is displayed. The sample illustration indicates a 5kg
weight value (Cal Point CP was set for 5kg).
Place the indicated mass on the platform. Keep the platform stable during this
period.
Press the G/N/T/ Menu button, -C- is displayed while the Indicator stores the
reading and then displays the weight of the mass.
If the calibration was successful, the calibration weight is displayed and the
calibration data is saved automatically. If unsuccessful, refer to the trouble-
shooting section.
Remove calibration masses from the platform.
NOTE: If the Indicator is to be used for legal for trade or legally controlled applications, it must be calibrated and
the jumper removed from the CAL connector in order to lock the menus. The top cover of the Indicator should be
free to gain access to the CAL jumper. Refer to section 3.1 for sealing for legal for trade use.
