This morning at bootup the screen displayed the message "Slow PWR Up" and nothing else.
Things are still wonky with the battery voltage showing 153 volts and 6 amp flow.
It looks like there was an error in transferring settings that has corrupted your voltage calibration - and maybe other things.
This will need to be addressed in its own right, but let's look at your particular case to get you on the road.
What is needed is to restore the protected settings that normally are unaffected by reading and writing setups to/from the CA. These settings calibrate the CA voltage and current measurement ability and are calibrations done at the factory for your particular CA. That said, there are 'generic' calibration values that can be used instead that will work fine and are typically only a few percent your specific calibrated settings.
(1) The first thing to try is to load up an older setup file that you read from your CA - ideally you saved one immediately when you got the device. Although you can't normally see them, these settings are in there when you read from the CA. To make the values visible, enable "Preferences/Show Protected Settings". Jot down the values in the dark protected settings rows. You may need to go back to an older Setup Utility, but the idea is to transfer these few items by hand, so - annoying but no compatibility problems. In any case the setup file must have been read from the CA - one you just created and wrote to the CA will have default values instead of the stuff in CA memory.
If you can't locate an appropriate setup file you will just need to use the defaults. This is fine (I have CAs that long ago got a brain-wipe and they work happily...).
(2) Next you want to update your CA with 3.1. Check the boxes on the update screen for "Reset settings to defaults" AND "Reset calibration settings". This will clobber the ALL bogus values in your CA with good default values - including the calibration stuff.
(3) Next, use the tab with the "3.1 New Settings" and fill in your desired configuration. If you found your earlier calibration settings, do the "Protected Settings" checkbox thing and enter the previous values. Be sure to check the box for any protected setting that you change.
(4) Now write the setup to the CA. All your new configuration as well as all protected settings with a checked box
will get written. (Best to save the new Setup to file as a new baseline config...)
Your Ca should now have working values (your original calibrated ones if you had them) and should make electrical measurements properly.
(5)Go for a ride and try not to curse us out too much for this slip-up....
Thanks for the post - we'll look into this ASAP.
