Formula for Determining Battery Life
The following calculation will determine the battery life for UNIDATA
battery packs (Model 6910A):
Life (days) = [ST/(RT+35)] * 3300
ST = Scan Time (seconds)
RT = Run Time (milliseconds)
… where external instrument load does not exceed 20mA.
The run time is determined by examining Address 1 of the PROLOGGER
(Block 0, locations 1 and 2), where the program run time is saved.
6910A battery packs have a maximum life of 3 years.
