               Z   =  (X + Y)/2  This (Z) voltage will be the operating voltage for that  particular filled capsule size.  Repeat the same procedure for Five time at X & Y Voltage to verify the operating voltage is working significantly.  Then the req. ECS voltage for that particular filled capsule Size will be incorporated in BMR after doing the validation of first three Batches. Always starting the batch at the set ECS voltage mentioned for the particular Product.
5.8.4  After completion of batch rotate the dimmer stat anticlockwise & switch off the toggle switch.
