1. Decimal Point DigiCell devices provide measurements in fixed point form The position of decimal point can be selected by decimal point selection box Display Unit ko Display unit is only used for user interface of built in device display and for PC software The unit has no Single Interval computational function It can be selected to appropriate unit by the 3 10 7 3000 00 selection box Scale Type e and Max values Scale Type specifies how e will be handled Can be choosen from Single Interval Multi Interval and Multi Range e value is the increment or decrement of displayed value when load changes e value is based on the least significant decimal digit of measurement value i e the display value will increase or decrease by 0 02 if decimal point is selected as 1 00 and e selected as 2 The device uses only one e value for all range if Single Interval selected It displays the Maximum alert message over the Max value with a tolerance On Multi Interval or Multi Range selection two e and Max values will be available for selection as el e2 and Max1 Max2 Basically el is used for measurements below Max value and e2 is being used above Max value Max2 value corresponds to the alert value The difference between Multi Range and Multi Interval is the behavior of output when Max exceeded and fallen below The el is used below Max1 and e2 used above Max1 i2.
