TWO MEASUREMENT MODES: Features dual displays, including a jumbo LCD and a 40-dot tri-color LED bar graph. It offers 2 modes, pin (%WME) and pinless (REL), and it has a 9V battery, remote pin-type probe, manual/auto-calibration, and a hold function. DEEP SENSING: For an accurate read with pin mode, use the attached pins or the 46" cable with pins and insert it into the surface material.
