CWS-BA-e-0610168 Basic operation8.1 Turn on/offTurn balance on/off by using the ON/OFFkey.The balance will carry out a self-test Assoon as the weight display shows "0" inall the three display windows your bal-ance is ready to weigh.a00.000 Kg 0.00000 g(or last used reference weight)8.2 Automatic switch-off function AUTO OFFTo save battery life, the balance is equipped with an Auto OFF function.This switches off the balance after a time of approximately 5 minutes after the lastweighing or key operation. It is possible to enable/disable the Auto OFF function (F-04-05) in the menu (see chpt. 14.2).8.3 Balance zero display/zero trackingEnvironmental influences can lead to the exact figure of zero not being displayed inspite of an empty weighing dish. It is, however, possible to reset your balance to zeroat any time and thus ensure that weighing really does commence at zero. Setting tozero when a weight is applied is only possible within a certain type-dependent range.In the event that the balance cannot be reset to zero with an applied weight, thisrange has been exceeded.To reset the balance to zero, press key . A triangle [W ] pops up next to the [ a ]symbol on the display.Notice:The balance has an automatic zero reset function (zero tracking). This function (F-04-01) is activated by the factory in order to compensate the normal zero shift due tovariations in temperature, air pressure etc.In the event that small quantities are removed or added to the material to beweighed, incorrect weighing results can be displayed due to the “stability compensa-tion“ in the balance. (Example: Slowly draining fluids from a container on the bal-ance).When apportioning involves small variations of weight, it is advisable to switch off thisfunction.If Zero-Tracking however is switched off, the weighing display becomes more busy.8.4 Stability displayIf in the display next to the [ ] symbol a circle [c] appears, the balance is a stablestatus. If the status is instable the [c] display disappears.
