Appendix L. RF400/RF410 Average Current Drain Calculations
EXAMPLE #3 (Base RF400/RF410 in “<0.4 mA, 8 sec Delay” standby mode)
The RF400/RF410s in this example are configured for the lowest possible average standby mode current (Advanced Setup Menu selection 7). The same amount and frequency of data are collected as in Example 1.
It = Is + Ih + Iq + Ir + Ii
Calculating each term:
Is = table mA value = 0.4 mA
Ih = |
| L (ms) | ⋅ 73 mA = | 8200 ms | ⋅ 73 mA = 10 mA ("long header"length = 8200 ms) | |||||

|
|
| T (ms) |
|
| 60,000 ms |
| |||
Iq = |
| 20 (ms) | ⋅ 73 mA = 0.025 mA |
| ||||||
| 60,000 (ms) |

Ir = | [45 (ms) + 20 ms] | ⋅ 24 mA = 0.026 mA | ||||||||
