4. CALIBRATION
For best results, calibrate the scale at regular intervals. (Calibration weights are not
supplied with the scale.)
CAUTION
USE EXTREME CARE WHEN HANDLING CALIBRATION WEIGHTS
AS THEY ARE VERY HEAVY. IMPROPER LIFTING METHODS OR
MISUSE OF CALIBRATION WEIGHTS MAY RESULT IN PERSONAL
INJURY. MULTIPLE WEIGHTS MAY BE USED TO EQUAL THE
REQUIRED CALIBRATION WEIGHT
NOTE:
• Ensure the appropriate calibration masses are available before beginning
calibration (see Table 4-1).
• Ensure that the scale is level and stable during the entire calibration
process.
• Calibration is unavailable in Dynamic Weighing Mode.
• Allow the scale to warm up for at least 2 minutes after stabilizing
to room temperature.
• To abort calibration, press
UNITS Cal , or power off the scale.
TABLE 4-1. CALIBRATION WEIGHTS.
Model Calibration weight (kg/lb)
C11P9 9 / 20

4.1 Span Calibration
Span Calibration uses two points to adjust the scale. The first point is the zero value
where there is no weight on the scale. The second point is the Span value where a
calibration mass is placed on the scale.
To select the weighing unit to be used for calibration,
press the
UNITS Cal button until the correct unit is
displayed.
Press and hold the UNITS Cal button until “CAL” is
displayed.
