KEYPAD FUNCTIONS, CONT.
ZERO/REVIEW KEY
This key performs two functions. In normal operation, pressing this key will cause an
immediate zeroing of the weight display up to the selected limit of 4% or 100% of the scale’s
capacity. Note that this selection is made during the setup and calibration of the indicator.
Pressing this key after the key will enter the Review mode of Setup and Calibration. Refer
to description of key and the Setup Review section of this manual for details.
TARE KEY (with diamond "T" symbol)
This is a dual function key. Pressing the TARE key alone (Pushbutton Tare mode) will store
the current gross weight as a new tare weight and cause the weight display to change to the
net weight display mode (Net annunciator turns on). Pressing it key after entering a numeric
value (Keypad Tare) will cause the value entered to be accepted as a new tare weight.
NOTE: Tare weights equal to or greater than scale capacity cannot be entered. In addition,
keypad tare weight division value must be same as scale division value. For example, a unit
with .005 lb as division value will display Error if you enter 1.003 for tare weight.
NET/GROSS KEY
This key is used to toggle between Net and Gross weight modes. The selected mode is
indicated by turning on the appropriate annunciator on the display. Note that if no valid tare
weight has been entered, pressing this key will cause a momentary “notArE” display error
and the indicator will remain in the Gross weight mode.
TARE KEY (with weight "T" symbol)
Pressing this key will display the current tare weight for three seconds.
UNITS/TEST KEY
This key performs two functions. In normal operation, it is used to select the units in which
the weight is to be displayed. The available units of measure ("unit1" and "unit2") are
enabled or disabled in setup. The available units include tons, pounds only, pound-ounces,
ounces only, tonnes (metric tons), kilograms, and grams. Note that not all combinations are
supported. Pressing this key after the key will enter the Test mode. The Test mode is
used to conduct a test of all display elements. Refer to description of key for details.

This key performs two functions. Pressing it when the indicator is off will apply power to the
indicator. If the indicator is already on, pressing this key will turn the indicator off.
Fn KEY (Legacy COUNT/SAMPLE Key)
This key is used to perform numerous functions. Note that the various functions of this key

ADD=5, 10, 25, 50, 75 prompts to select a sample size. When desired sample size is
displayed, press the ENTER key OR with ADD= (5, 10 etc.) displayed, using the numeric
