Appendix L. RF400/RF410 Average Current Drain Calculations
L-8
EXAMPLE #6
(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 of data are collected as in Example 1, however the
frequency of
collection
is changed from once a minute to once an hour.
