Automatic Zeroing if Scale is Under Zero

The scanner/scale is equipped with a feature that automatically zeros the scale if it has been under zero for five seconds. (See “Scale Automatic Zeroing” on page 37.) Local requirements may require temporarily disabling this feature during certification. For the most accurate weighing function, it is recommended that the automatic zeroing feature be enabled.

Verification of Automatic Zeroing if Scale isUnder Zero

1.Place 0.1 lb (0.05kg) on the scale and press the Zero Push Button. The Remote Display should read 0.00lb (or 0.00kg ).

2.Remove weight. The Remote Display should read lb ,then, after five seconds, the display should read 0.00lb (or kg).

Preparing the Scanner/Scale for Calibration

1.Assure that the scanner/scale is stable, secure and properly installed. (Refer to Section 2, Site Preparation and Installation for instructions on the proper installation of the scanner/scale).

2.Power-up the scanner/scale.

3.Allow the unit to reach temperature equilibrium for at least one hour. If the scanner/scale is already at room temperature, allow at least 15 minutes for acclimatization.

4.Before performing the calibration, the scanner/scale must be pre- stressed with a weight of more than 30 pounds (15kg). With power turned on, place the entire weight set (including the case) on the weighing surface of the scale. The display should show an

underscore and three hyphens , which is the over- weight indication.

5.Remove all weight from the weighing surface and ensure that there are no obstructions in the debris chutes of the scanner/scale. See Figure 2-3.
