Change
Use this Change button when you want to set the battery remainder time and the last
battery exchange date and time to the desired values without using the CMU module’s
BATT.SET switch.
The battery remainder time (*) and last battery exchange date and time are recorded in the
CMU module. If only the CMU module is replaced, this makes it impossible to compute the
correct battery remainder time. To solve this problem, set the battery remainder time to the
correct value by using the Change button.
Clicking the Change button causes the specified battery remainder time and last battery
exchange date and time to be recorded in the S10V Base System’s operation history, which is
stored in the file ‘S10log.txt’ in the same folder in which the Base System is installed.
<S10log.txt>
(*) The battery remainder time is computed as follows:
Battery remainder time = useful battery life time - accumulated power failure time
where the useful battery life time is 365 days times 24 hours, and the accumulated power
failure time is one that is recorded in the CMU module’s internal memory. The battery
remainder time is computed by software tools using those values.
