5.1 Entering, Recalling and Adding/Subtracting Tare Weights
This section will describe the different tare-related operations you can perform from the weighing mode. The tare
weight can be set by one touch tare using the
TARE
key (Section 5.1.1) or, if the value is known ahead of time,
can be entered digitally using the digital tare function (Section 5.1.2). Tare addition and subtraction can also be
done digitally or by using the
TARE
key. If a tare weight has previously been programmed to a preset key, that
tare weight can be recalled (Section 5.1.3).
Note
The following SPEC codes must be set properly to allow these operations before continuing: SPEC 25, Bit 3
- MANUAL TARE CANCELLATION sets whether or not the tare weight can be cancelled from the keyboard.
SPEC 25 also controls whether TARE SUBTRACTION (Bit 2) and TARE ACCUMULATION (Bit 1) are allowed
or inhibited and whether AUTO TARE CLEAR WHEN REZERO (Bit 0) takes place or not. SPEC 26 controls whether the
scale allows DIGITAL TARE entry (Bit 3), whether the scale can do ACCUMULATION WHEN TARE (Bit 2), if there will be
ZERO TRACKING WHEN TARE (Bit 1) and WEIGHT RESET WHEN TARE (Bit 0). SPEC 27 sets whether or not TARE
AUTO CLEAR is activated (Bit 3). (For further instructions on how to set the specifications, see Section 3.2.1)
