Appendix H: Zero & Tare

There are two functions which are similar, yet actually different: Zero & Tare:

The Zero function supplies both manual and automatic ways to clear the gross weight.

The Auto-Tarefunction supplies a way to define the meaning of the setpoint parameter.

H.1 The Zero function

This function supplies both manual and automatic ways to clear the gross

weight:

Manual Zero

The manual zero is available only in the general mode, not in the fill-mode. Its effect is temporary – it expires upon card reset. The manual zero is accessible via two ways:

*Hardware input: Turn on digital input #3 for two seconds.

*Communication:

*When accessing the communication directly: Send the ‘z’ command (section 4.1/i).

*When using the LCIC-WIM ActiveX:

Call the Apply_Temporary_Zero function (section 4.3.5).

Auto Zero

The auto zero is available only in the fill-mode, not in the general mode. Its effect is temporary – it expires upon card reset or upon exiting the fill-mode.

The auto zero operation occurs when some user’s pre-defined condition is satisfied. For more details refer to section 3.3.2.2.
