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.
