6.4.3 TARE Key Function
If the tare acquisition is greater than zero (+1/2
graduation), set the display to the net mode and apply
the new tare.
If the tare acquisition is negative or in motion, the
indicator stays in the current mode and no tare is
performed.
6.4.4 Overload and Underrange Conditions
Overload conditions occur when the weight exceeds the
selected scale capacity by greater than 105%, or
overload may indicate a defective load cell or load cell
simulator input.
NOTE: If the indicator is configured for legal-for-trade
(PAZ = 1.9%), overload occurs at 103% of full scale
capacity if push-to-zero has already captured 2% of full
scale (105% minus 2% = 103%).
Underload conditions will occur when scale input is
greater than -400 grads, or underload may indicate a
defective load cell or load cell simulator input.
Figure 6-1 shows the indicator display associated with
over and underrange conditions.
See Section 9.3 on page 67 for information about
additional error and display messages.

Clear Entry ( CE ) key to clear an incorrect value.
Both auto and fixed tare values can be recalled by
