Remote Calibration
The remote calibration inputs perform the same function as the CALIBRATE push-button switches on the
front panel of the control module.
Quick Calibration Changeover
The AUX input works in conjunction with SW1 (both channels) and SW2 (channel 2 only) to select the
target tab and shell material combinations as presented in the table below.
When the AUX input is activated or deactivated, the SD220/SD230 changes to accommodate the new
material combination and displays, for approximately 2 seconds, a two-character abbreviation indicating
the selected targeted materials. The display interpretation is as follows:
Al – aluminum tab on aluminum shell
St – steel tab on steel shell
AS- aluminum tab on steel shell
The two-character indication also displays at powerup indicating the current selection.
