DuSLICOS allows automatic calculation of the coefficients for K
measurement.
The according parameter is "DC Levelmeter current 50% full scale" (see DuSLICOS DC
Control Parameters 4/4). The setting of this parameter affects the shift factor (K
the DC levelmeter. The set current will result in 50% full scale of the levelmeter result
registers if the integration of the DC levelmeter is done over the integration period
determined by the ring frequency. Example: if the DC levelmeter current 50% full scale
is set to 2 mA and the actual current to be measured is 3 mA, the value of the levelmeter
result register is 24575
DuSLICOS uses finer steps as the examples listed in
the K
The expected “Current for Ring Off-hook Detection” (see DuSLICOS DC Control
Parameter 2/4) of 20 mA, for example, is entered in to the program and then K
automatically calculated to achieve 50 % full scale if the current of 20 mA is integrated
over the set ringer period.
The integration function accumulates and sums up the level meter values over a set time
period. The time period is determined by the programmed ring frequency. A ring
