TARING AN ITEM OF UNKNOWN WEIGHT
To weigh an item in a container, the weight of that container must first be subtracted from the overall weight
to obtain an accurate weight reading. This is known as taring.
For your convenience, the 400ES indicator retains this tare weight value even when the unit is powered off.

Select the desired weighing unit by pressing the lb/kg key until that unit is
indicated on the display.
2.
If necessary, press the ZERO key to obtain a weight reading of zero.

Place the empty container on the scale’s platter and allow the weight indication to
stabilize.

annunciator on.

TARING AN ITEM OF KNOWN WEIGHT
If the weight of the container or object is known, you may enter this weight via the keyboard. This value
must be rounded to the nearest scale division. For example, on a 100 x 0.02 lb scale, you must enter the
tare weight value to the nearest 0.02 lb.
For your convenience, the 400ES indicator retains this tare weight value even when the unit is powered off.

Select the weighing unit of the known tare weight by pressing the lb/kg key until
that unit is indicated on the display.

made, you can press the ZERO key as a backspace key to clear the entry and
re-start.

Press the TARE key. If the tare weight is valid, the display shows zero weight
and turns the NET annunciator on. If the tare weight is invalid, you will see an
error message. Refer to Appendix D for displayed error codes and their
meanings.
