I run a Warrior 8 system, for a Temp Observation log, it started yesterday, the system is showing glitches in the log, I've checked the tool, head connection, all cables, and all external connections, when the Warrior system is isolated, meaning not connected to anything, the voltage is still showing fluctuations from 0-4. The error message when the laptop is interfaced is "Ten M Open Line Error" what's causing this? the system is isolated and should show 0. I need real time help, any suggestions would be really helpful.
