KEYPAD FUNCTIONS
CAL/ MODE:

dure as outlined under the CALIBRATION section. After unit is on or
calibrated, press and release the Cal/Mode key will change the weigh-
ing mode. When balance is turned on the unit initially defaults to the
gram (g) mode. The following modes may also be selected: ounces
(oz), penny weight (dwt), troy ounces (ozt).
ON/ MEMORY:
Press and release to turn on balance. Once the unit
is on, the same key operates the additive memory feature. The follow-
ing steps outline the procedure for cumulative weighing of samples.
1) If needed, place container on weighing pan, wait for stable reading,
then press and release "tare" to return balance to zero and permanent-
ly remove container weight from the additive procedure.
2) Add first sample until desired weight is achieved.
3) Press and release "memory" to reset unit to zero. The memory
symbol (up arrow) appears in the upper left corner, indicating the
previous weight value has been stored.
4) Add second sample until desired weight is achieved.
5) Press and release "memory" again. The (up arrow) symbol will
disappear and the display will show the combined weight of the first
and second samples. Repeat steps 3 through 5 for additional items.
NOTE: When the entire load is removed from the balance, the display
will show a negative value equal to the tared value of the container if
used. To reset the balance to zero, press and release the tare key.
TARE:
Press and release tare to reset the balance to zero. Tare
can be used to eliminate the weight value of a container from a sample
or procedure. The container weight is permanently removed from the

value of a container will be displayed as a negative number. Press and
release tare again to return the balance to zero.
