When configured for eddy-current measurement systems, the supplied DC voltage supports proper probe driver operation and assists monitor channels in maintaining valid gap voltage measurements. Gap verification practices commonly target nominal operating regions near -10 VDC to confirm correct probe-to-target positioning and transducer linearity during commissioning.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can the input voltage range be changed in the field?\u003c\/strong\u003e\u003cbr\u003eA: Yes.
