5-1. Preset tare function
The preset tare function allows you to register a known tare by entering the value. A preset tare can be linked
to a program and retrieved when you call program data.
* The Measurement Act prohibits inputting a preset tare outside the indication range in which the minimum
scale interval can be used (up to 1500 g when the weighing capacity is 3000 g and up to 3000 g when
the weighing capacity is 6000 g).
* You cannot register only a preset tare as program data. You also need to register other setting values such
as the lower limit.
* You cannot use the Preset tare function together with the Counting function or the Subtractive weighing
function.
* You cannot use this function together with the Automatic tare function. If you set both functions, the system
enables the Preset tare function and disables the Automatic tare function.

limit, upper limit, and preset tare in the program 2.
* If the lower limit is not set, you cannot register the preset tare.
* You can also register a tare set in the One-touch tare using this
procedure. However, you cannot register a tare that exceeds one half
of the weighing capacity.
Preset tare function - How to register a program
Refer to the section "How to register/edit … through regular setup" of each Multi-function. (Refer to Chapter 6.)
