info@tursdaletechnicalservices.co.uk 1. Introduction Electrical balance BT series are designed for use in laboratories and many others technical applications, where high measurements precision is not required. All balances are metrologically tested by manufacturer and they are not designed for calibration certificate. According to order, balances may be calibrated.

Keys and indicators Keys functions description: - switch-on/switch-off (standby), - numeric key / menu, MENU → ← - tare (subtract package weight from weighed mass) - numeric key / data output (print / transmission), → ← - numeric key / zeroing (balances for direct sale use only), indicator - result stabilisation, bar indicator...

Place the balance on stable foundation, in place not subjected to mechanical vibrations and air movements. 3. Unscrew protection rod 10 and take it out with protection cap 11 (if it appears in scale).

info@tursdaletechnicalservices.co.uk Attention: Pos. 10 and 11 are optional. If balance was moved from environment with lower temperature to the room with higher temperature, condensate can be formed on the surface of balance. In this situation it is forbidden to turn balance on, because balance can be damaged. Before turning on balance, it should stay in a new environment for 4 hours in order to acclimatization.

Charging of accumulators is made automatically, when balance is connected to power supply unit (also during weighing) Charged state of accumulators can be checked by auxiliary function bAttErY (bat VoL option) 11. Accumulators (batteries) exchange 1. Remove pan lid that shields scale pan. Remove pan cover and put it near the balance.

Start-up Leave the pan empty, plug the feeder to the mains (~230V/50Hz) and plug the feeder connector to the 12V power socket at the back of the scale The scale proceeds with following start-up actions: Basic electronic components tests: C1, C-2, ... C-6. bt...

info@tursdaletechnicalservices.co.uk 15. Balance special functions All balances, besides the basic metrological functions: weighing and tare setting, have a set of balance special functions. Basic set of includes the following special functions: - Automatic zeroing function (AutotAt) - pieces counting (PCS), - Convert mass units (UnIt) - Convert percentage (PErCEnt) - Preparation of recipes (rECIPE)
