Important Usage Notes:
- This is a process calibrator intended for use at <=30 Vdc. Do NOT use for testing AC signals or any voltage >30 Vdc.
- The input and output terminals are not electrically isolated - avoid simultaneous connection of systems which are intended to remain electrically isolated from each other.
- It is recommended to avoid using the device while charging to prevent potential ground loop issues.
