INTRODUCTION

General and Safety Information

 Risk of Electrical Shock: Disconnect all power sources before making cable connections to the floor scale platform or indicator.

 For use in dry environments only.

 Do not operate in hazardous areas.

 Read and understand all operating instructions before using this product. Keep this manual for future reference.

 Record the weight shortly after placing a load on the platform. After extended periods, the load cell’s output signal may result in a less accurate reading.

 Avoid extended exposure to extreme heat or cold. Optimum operation is at normal room temperature. See operating temperature range in the specifications table. Allow the scale to acclimate to room temperature before using.

 Allow sufficient warm up time. Turn the scale on and allow up to 2 minutes for internal components to stabilize before weighing.

 Electronic scales are precision instruments. Do not operate near cell phones, radios, computers or other electronic devices that emit radio frequencies that may cause unstable readings.

 This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with this manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case the user will be required to correct the interference at their own expense.

 Avoid using in heavy vibration or heavy airflow conditions. This also applies when the floor scale is integrated into conveying systems.

Auto HOLD:(Default setting)

When USER-HOLD-HLD.MOD is set to AUTO, the hold mode is autohold mode: different subjects can be weighed one after another without pressing any buttons. After entering this working mode, the scale will freeze and display number if the scale is stable. If the scale is not stable, but the variation is less than USER-HOLD-HLD.RNG, the scale will average data in USER-HOLD-AVG.TIM, then freeze and display the number. Only the weight that is over USER-OTHER-NLD.RNG can be frozen. If the held weight is removed, and a new load is placed on the scale, the scale will automatically hold the new number of the load. Scale will exit HOLD mode according to the setting of USER-HOLD-HLD.TIM.

If the time of scale variation is over USER-OTHER-NLD.RNG or is more than

USER-HOLD-STB.TIM, STB.ER

will be shown, press TARE/PRESET to start averaging again, or press SETUP key to exit.

User/Service Manual received. After this, the indicator will automatically continue to the next step. If this point can not be calibrated correctly (E.g. the weight load on the scale is too small, the input data is incorrect…), it will display “ CAL.Er

” and return to step a for re-calibration. c.

When End.y

is shown and y is flashing, enter a command to exit calibration or go on to the next calibration. Use keys to select yes or no , use TARE/PRESET to confirm. If yes is selected, you will be directed go to step8 to end calibration; if no is selected, continue to the next step. d.

When 100%FS weight is displayed after CAL.P2

is shown, it will be calibrated on standard weight for the second point. Place corresponding weight (more than 10%FS weight, and larger than the weight used on CAL.P1

) onto scale. The next operation steps are the same as explained in step b. e.

When End.y

is shown and y is flashing, Use key to select yes or no , use TARE/PRESET to confirm. Refer to step c for more details. f.

When the third standard weight displayed after CAL.P3

is shown, it will be calibrated on standard weight for the third point. Place corresponding weight (more than 10%FS weight, and larger than the weight used on CAL.P2

) onto the scale. The next operation steps are the same as explained in step b. g.

When the stable and reasonable data corresponding to the standard weight has been received, the indicator will automatically go to Step8. Otherwise, it will display “ CAL.Er
