Appendix L. RF400/RF410 Average Current Drain Calculations
L-2
The base RF400/RF410’s total average current
(It) can be calculated over an
interval (T) as follows:
It = Is + Ih + Iq + Ir + Ii
Is = {table value}
REMOTE
The average current drain of a
remote
RF400/RF410 being collected on
schedule has 4 contributors:
1)
The STANDBY AVG RECEIVE CURRENT – Is
2)
The average transmit current from data transmission – Id
3)
The average receive current of data request receptions – Ir
4)
The average receive current from “time of inactivity to sleep” – Ii
The remote RF400/RF410’s total average current
(It) can be calculated over an
interval (T) as follows:
It = Is + Id + Ir + Ii
Is = {table mA value}
