MENU 8.1 – CALIBRATION
CAL (D.A.N. 8121) Dead Weight Calibration
Procedure to calibration with known weight:
1. Enter (D.A.N. 8121) and press
, the indicator will display WT CAL and prompt to zero the scale. Press and
hold the ZERO key to zero the system.
2. Scale will now prompt "ADD WT". Place a known weight on system (ex. 5000 lb. test weight) on the scale
platform and press the ON key. If calibration weight is at least 5% of the scale capacity, the message "CAL" will be
displayed.
3. If the scale capacity is not at least 5%, the system will not accept the calibration value and display the message
"ADD WT". Add more weight to the scale until the 5% capacity weight has been exceeded.
4. After the 5% capacity weight has been reached, the indicator displays the message "CAL". The weight value
estimated to be on the scale at that time is displayed. The weight on the scale is estimated based on the previous
calibration value.
5. Correct the weight value by pressing the or key to increment the digit and the or key to select
the digit to change.
NOTE: The scale will not accept the weight entered if motion is detected (weight is not stable) and will display the error
message "MOTION."
6. When the display reads the correct weight, press the key to automatically determine and store the full-scale
calibration value. The message "GOOD" is displayed for a successful calibration.
T CALB (D.A.N. 8123) Temperature Calibration
The scale compensates for changes in temperature that affect the circuitry in the indicator. The scale does not
process load cell signals during TCALB. The CAL annunciator is on momentarily during TCALB based on model. If
set to ON, the indicator recalibrates often when first turned on. Recalibration decreases as the indicator warms up.
CALMAT (D.A.N. 8124) Calibration Match
"Scale Matching" functionality allows the user to adjust the calibration number by inputting two weight values. The
first weight value is the "display" weight (current indicator weight). The second weight value is the "actual" (or real)
weight value. The calibration value will scale all weight values (including balance points). Calibration = "actual
weight" / "display weight"
