of the weight display up to the selected limit of 4% or 100% of the scale's capacity. This selection

TEST KEY - The TEST key is used to conduct a test of all display elements. The test consists of
six (6) cycles, each lasting two (2) seconds:
TEST
1. All horizontal segments and the left 1/3 of the bar graph will turn on (no annunciators).
2. All vertical segments and the center 1/3 of the bar graph will turn on (no annunciators).
3. All annunciators, decimal points and the right 1/3 of the bar graph will turn on.
4. All display elements off.
5. The calibration numbers (C1 - C4).
6. The model no. 748P and the software version X.X.
Following the display test, four (4) calibration numbers (C1, C2, C3 and C4) will be indicated in sequence.
These numbers correspond to the settings of the setup parameters as well as the calibration setting of the
indicator. It is a good idea to copy these numbers down and place them in a safe location AFTER completion
of the calibration process.
GROSS KEY - The GROSS key will cause the weight display to return to the Gross Weight
mode. The Gross annunciator will be turned on.

GROSS
TARE KEY - There are two (2) TARE keys on the 748P. The top TARE key is used to
momentarily display the stored tare value. The other TARE key is used to enter a new tare
weight value. If the push button tare is enabled during setup and calibration, pressing the red
T
TARE key will cause the current gross weight to be stored as the new tare weight and cause the
TARE
weight display to change to the net weight display mode ( Net annunciator turned on). If the push
button tare feature was not enabled, pressing the red TARE key will cause the current value of
the tare weight to be displayed ( Tare annunciator turned on). The tare weight may be retained
by pressing the ENTER key or may be changed by keying in the new tare weight value and
pressing the ENTER key. You may also store the current gross weight as the new tare value by
simply pressing the GROSS key then pressing the ENTER key. Once a tare weight has been
TARE
entered the display will automatically change to the net weight display mode. NOTE: tare
weights equal to or greater than the scale capacity cannot be entered.
