I met two problems as follows(Use ADC11-10 with real time continous m):
(1) How to set the scan time in Picolog?
In the user manual it states "scan time is the total time to take the set of readings for a sample. The scan time should be at least three cycles at the min frequency that you wish to measure"; Now if I want to record data at sample rate of 100ms/per sample, then which scan time I should set, <100/3ms or >100*3ms?
(2) Using constant voltage from a battery, why the voltage reading output from Picolog is different from direct reading from Multimeter even though the sampling rate is the same: both are at 500ms/per sample? Additionally, it showed that voltage reading from Picolog is always higher than what got from Multimeter by around 1 or 2mv. Below are the test data I have:
Multimeter reading(mv) Picolog reading (mv)
Eager to hear your reply, thanks.
