Display Calibration Audit Numbers (Shift key then F5 key)

Press the

number, configuration number and the software revision ID number. The audit numbers

can also be accessed via the

CFG Test key selection 1.

The DT220 provides a Scale audit number an application audit number and a

configuration number. They are used to indicate changes to calibration data, application

data and configuration data. They can be used in place of mechanical seals by some

regulatory agencies.
The scale and configuration audit numbers increment each time a scale parameter or

calibration parameter is changed (deadload or weight conversion factor). The

configuration audit number increments each time any configuration setting has been

changed. The scale, application and configuration audit numbers increment each time

new firmware has been loaded.
If physical seals are used, then remove the internal function lock jumper TB3 terminal 7

to TB6 terminal 7 before sealing. Calibration parameters cannot be accessed when the

function lock jumper is removed. Enter Password will be displayed when locked and

there is no password to disable the function lock from the keypad. See TTL Input Test for
