1. INTRODUCTION The TB series of electronics balances provides an accurate, fast and versatile series of general purpose balances with counting and % weighing functions. All models have stainless steel weighing platforms on an ABS base assembly. All the keypads are light touch switches and the displays are large easy to read liquid crystal type backlit displays (LCD).
Keep the scales clean. Do not stack material on the scales when they are not in use. 3.2 INSTALLATION of TB SERIES Level the scale by adjusting the four feet. The scale should be adjusted so that the bubble in the spirit level is in the center of the level and the scale is supported by all four feet.
3. KEY DESCRIPTIONS Zero or Enter Set the zero point for all subsequent weighing. The display shows zero. A secondary function, as "Enter" key when setting parameters or other functions. Tare Tares the scale. Stores the current weight in memory as a tare value, subtracts the tare value from the weight and shows the results.
4. OPERATION 4.1 ZEROING THE DISPLAY You can press the ZERO/ENTER key at any time to set the zero point from which all other weighing and counting is measured, within 10% of power up zero. This will usually only be necessary when the platform is empty. When the zero point is obtained the display will show the indicator for zero.
4.4 PERCENT WEIGHING The scale will allow a sample weight to be shown as 100%. Then any other weight placed on the scale will be displayed as a percentage of the original sample. For example if 350g is placed on the scale and the % key is pressed the display will show 100.00%.
