Initially I was considering a TC08 to log both temperature and voltage inputs, but I don't think it will be suitable
The requirement is to monitor a vehicles start up behaviour, cold cranking and battery voltage, RPM and temps
x5 k type
x1 Cold Cranking current - TA167 Current clamp input via PP264 terminal board
x1 Vehicle battery voltage - PP264 terminal board (with voltage divider)
x1 RPM input signal (maybe not essential but is preferable)
The obvious question would seem to be logging rate in order to properly capture;
Inrush current transients at start up
RPM signal transients
What is the maximum logging rate for something like the TC08 and is this an 'aggregate' logging rate, i.e. does the unit divide the aggregate logging rate by the number of active channels. For instance if the unit could log 100 samples a second and 4 channels were active then 25 samples a second per channel?
Do you have a device which can be used as an RPM pickup?
My guess is needing to capture the transient inrush current and transient RPM behaviour will not be possible with a TC08, along with the total number of channels required, but if you could advise what is most suitable.
All of the data collected has to synchronous and 'aligned' so any combination of units would need to 'synch' with each other.
