CHAPTER 3 SCALE TESTING AND CALIBRATION
3.8 CALIBRATION
Calibration – The EC Series’ calibration can be calibrated using full scale capacity as the best method for
the most accurate results, this is referred to as span calibration.
Calibration Weights – Before beginning calibration, make sure that the required calibration weights are
available. The model-specific calibration points are listed in the Table 3-5.
3.8.1 Calibration Points
NOTES
: 1. Calibration Units kg or lb are selected in the (Setup mode) sub-menu.
2. ASTM Class 4 or OIML Class F2 weights are required for calibration.
3.8.2 Span Calibration
1. Enter calibration by holding down the
Zero
button until CAL is displayed in the Count window.
2. The required calibration weight is displayed (ex. 3000g for a 3kg model). At this time, a different
calibration weight value can be entered via the numeric keypad.
3. Place the corresponding calibration weight on the Pan. the display flashes until the actual weight
is registered and the calibration process ends (the scale momentarily beeps before exiting to
normal weighing mode).
NOTE
: 1. Different values of calibration masses can be used on the EC scale, however, it is recommended
that the calibration mass used is close to or matches the maximum capacity of the scale for
best accuracy.
2. The calibration procedure can be canceled at any time by pressing the
Zero
button.
