|
Problem: Some devices turn off unexpectedly and sometimes without any obvious trigger. In the past, the only time this was an issue
was during mass scans. Now with the automation of measurements, this is a major problem as it prevents longer parameter scans.
Thursday, August 05, 2021, 08:00: Kevin setup the CANBUS snooper by hooking it up on the magnet card loop port. |
