3. CALIBRATION AND SEALING
Model CD-11 Indicator requires span calibration before using. Span calibration ensures that the Indicator reads
correctly within specifications using weight values of 20% to 100% of capacity. For best results, calibrate at or near
full capacity. Calibration unit can be set to either kg or lb.
When the Indicator is used in Legal for trade applications,
the calibration menu is locked out and is not accessable. This is to prevent unauthorized personnel from changing
calibration. 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.
Calibration 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.
Procedure
• With the Indicator ON, press and hold the Zero/
Menu button until MENU is displayed. When you
release the Zero/Menu button, CAL is displayed.
• Press Zero/Menu button, -C- is displayed. The
scale base MUST be stable during this period and is
establishing a zero point. After a few seconds, the
requested weight value is displayed. The sample
illustration indicates a 30kg scale. (Cal Point CP was
set for 30kg)
• Place the indicated mass on the platform. Keep the
platform stable during this period.
• Press Zero/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 mass
is displayed and the calibration data is saved auto-
matically. If unsuccessful, refer to the troubleshoot-
ing section.
•Remove calibration masses from platform.
NOTE: If the Indicator is to be used for legal for trade
applications, it must be calibrated and the jumper re-
moved from the CAL connector in order to lock out the
menus. The top cover of the Indicator should be free to
gain access to the CAL jumper. You must also set Setup
and read LOCSW to ON. Refer to paragraph 3.1 for
sealing for legal for trade use.
