1. GENERAL INFORMATION BWLC precision scale enables fast and accurate mass measurements under laboratory and industrial conditions. The device is equipped with an internal battery which allows its operation in places where there is no access to the mains. The BWLC features a stainless steel weighing pan, and a backlit LCD guaranteeing clear weighing result presentation.

Install the weighing pan, follow the below figures: BWLC/C1/R, BWLC/C2/R scales BWLC/C1/K, BWLC/C2/K scales 6. START-UP AND OPERATION 6.1. Levelling To level the weighing instrument turn its feet. Keep turning the feet until the air bubble takes central position: 6.2.
In case the weighing result is not zero after indication stabilisation, press key. 6.3. Warm-Up Time For correct scale operation, the workroom temperature must range between +15C +30C. It takes 30 minutes for the device to warm up. ...
7. MAINTENANCE ACTIVITIES In order to ensure safety in the course of cleaning, it is necessary to disconnect the device from the mains. With this condition met, uninstall the weighing pan and other detachable components. Cleaning the weighing pan while still installed may cause damage of the measuring system.
Avoid drying the panes either using paper towel or forced air circulation since some fibres, grains or contamination of other type could permeate into the panes thus causing weighing errors. We do not recommend using driers when drying measuring glass tools. It is a frequent treatment to leave glass components on a rack to dry.

Options in case when the main unit is [g]: g (gram), kg (kilogram), ct (carat), lb (pound)*.
12. ADJUSTMENT option available for non-verified weighing devices exclusively In order to ensure the highest weighing accuracy, it is recommended to periodically introduce corrective factor of indications to scale memory, the said factor must be referred to a reference weight. This is so called adjustment. Adjustment has to be carried out: ...
12.2. User Adjustment User adjustment must be carried out using an external adjustment weight of class C Procedure: Enter <P1.CAL / 1.2.CA-u> submenu, edit box for declaring weight mass is displayed (the mass value must be 30% of the maximum capacity value).
Press key, filter values are displayed successively one by one: 1 - Fast, 2 - Average, 3 – Slow. Set respective value and press key to confirm, next go to the home screen. The higher filter value, the longer the weighing takes. 13.2.
There are, however, some cases when this function can be a disturbing factor for the measuring process, e.g. very slow placing of a load on the weighing pan (load adding, e.g. pouring, filling). In such case, it is recommended to disable the function.
