    • If you set GND to Guard, do not connect measuring instruments that are grounded at one end (e.g., Kikusui 149-10A High Voltage Digital Voltmeter, TOS1200 Current Calibrator) to this product. Doing so is extremely dangerous because the ammeter will be shorted and will not be able to measure current.
