Appendix L. RF400/RF410 Average Current Drain Calculations
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}
Ih = |
| L (ms) |
| ⋅ 73 mA | where L is the "long header"length | ||
| T (ms) | ||||||
|
|
|
|
|
| ||
Iq = |
| 20 (ms) | ⋅ 73 mA |
|
|
| |
|
|
|
|
| |||
| T (ms) |
|
|
| |||
Ir = | [45 (ms) + 2 ms per data point] | ⋅ 24 mA | (4 ms per high - res data point) | ||||
| |||||||
|
|
|
| T (ms) |
|
|
|
Ii = | 5000 ms | ⋅ 24 mA |
| (using default "time of inactivity to sleep" = 50) | |||
| T (ms) | ||||||

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}
Id = |
| [45 (ms) + 2 ms per data point] | ⋅ 73 mA | (4 ms per high - res data point) | |||
