1. SETTING UP THE BALANCE Cut safety tape off. Take balance off the box. Take all necessary to correct performance of balance elements off the box. After replace balance in place of use put scale and rest of elements on. Assembly of elements for scale with precision 10mg: - - Put pan scale (2) on gum mandrels Put cover on scale (1) using pins in back part of balance cover.
2. APPLICATION Electronic scale CY - CG is appropriate for precise measurements mass in laboratory conditions with possibility of setting to zero in all measure range. Balance calibration is done by CAL on balance keyboard. Functions accessible to user are divided into 4 parts: ! Functions for weighing units (press F key) - Weighing in grams, - Result with 3 places after dot, - Weighing in carats [ct], - Weighing in units from beyond SI: [GN], [mom], [oz], [dwt].
3. CONDITIONS OF APPROPIATE USING • scales should be used and stored in rooms without vibrations and shakes, without drafts and dust o o • temperature of air should be +15 C ÷ +35 C • during using balances changes of temperature shouldn’t be higher than 0,5oC per one hour • scales should be replaced on wall console or stable table, far from sources of heating • strong magnes is installed inside of balance – so it’s important to be carefull during weighing magnetic materials.
4. KEYBOARD Key ON/OFF is to turn display off. Others subassemblies are still suppplying and scale is in stage of waiting for further work. If user press this once again weighing stage with measure units are displayed. PRINT key is to send current state of display to external mechanism by connector RS 232 CAL key is to calibrate. It’s manual calibration. After press if scale starts calibration. There shouldn’t be any load on scale.
5. START AND SERVICE Before supply is turn on glass of weighing chamber should be draw Balance should be leveled. To level scale screw legs in order air bubble was in centre position. TIME OF HEATING It’s neccesary to wait untill scale gets heat stabilization. It’s time of own heating. User has to wait 15 min. in case of analitycal scales. Given values refers to scales that were in temperature of conditions of work before they are connected to suppling net. If scales were in much lower temperature (f.eg.
6. WEIGHING Before weighing or if the conditions of work changes (f.eg. if temperature of surrounding is higher then 3oC) scale should be calibrated according to way in point 7.
7. CALIBRATION To assure very precise weighing introduce correction factor to balance memory – it’s calibration.
7.1. Balance with external calibration Pressing key CAL causes calibration of balance - on display appears: (balance starts autotest for calibration –during test you cannot load the scale), and then order (it is command to put calibration mass on scale) calibration mass is given in grams. If you the mass on scale on display appears calibration and then take calibration mass off scale. After take calibration weight off scale balance shows zero.
