The mode switch is operated by the physical on on the main body of the electronic pen. Pre and release the on to cycle through the three working modes.Widely d in the auto repair industry: especially suitable for car repair technicians and family busine vehicle maintenance and repair, etc.Product name: Automobile circuit testing penProduct model: P50Voltage range: 5V-30VMaterial: plasticcolour: As shownPackage Contents:1 x Circuit test penOnly the above package content, other products are not included.Note: Light reflection and different displays may ca the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
