DT220 Users Manual version 1.a Configuration Parameters
18
Scale Parameter 8: Power-On Zero (N [disabled])
The power-on zero function zero’s the scale when power is turned on to the DT220.
Position the pointer to selection 8 and press the
Enter switch to toggle the Power-On
Zero function on (Y) or off (N).
Calibrate
There are 5 calibration selections.
1 Deadload first
2 Span first
3 Deadload only
4 Multi-point calib
5 Adjust Gain (tweek)
Use the Review (↑↑↑↑) and Cont. (↓↓↓↓) keys or the numeric keypad to move the pointer to a
menu item and then press the Enter key.
NOTE: Set the Scale Parameters and save into memory before calibrating the scale.
Calibrate 1: Deadload first
This function calibrates the scale by reading the deadload first and then reading the span.
Best results are obtained when the DT220 and load cells have reached thermal
equilibrium (power applied for approximately 30 to 120 minutes depending on load cell
size).
1. The DT220 prompts “Press ENTER to read deadload”. Remove all weight from the
scale. Press the Enter key. The DT220 reads the scale’s deadload weight. NOTE:
press the Cont. key to skip deadload read.
2. The DT220 display prompts “Enter calibration weight:”. Place the calibration
weight on the scale. Enter the calibration weight using the numeric keypad. Press
the Enter key. The DT220 reads the calibration weight.
Calibrate 2: Span First
This function calibrates the scale by reading the span first and then reading the deadload.
Best results are obtained when the DT220 and load cells have reached thermal
equilibrium (power applied for approximately 30 to 120 minutes depending on load cell
size). The deadload must be greater than approx. 1% of scale capacity. If it is not, then
calibrate deadload first.
1. The DT220 display prompts “Enter calibration weight:”. Place the calibration
weight on the scale. Enter the calibration weight using the numeric keypad. Press
the Enter key. The DT220 reads the calibration weight.
