- 1.3V lithium battery CR1632 (battery not included for air shipment due to postal regulations) - Flat carbide tip (spherical steel tip optional) - Power ON/OFF; ZERO set at any position - Absolute and incremental measurement Key benefits - Zero at any position enables quick relative measurements without re-referencing - Supports both absolute and incremental measurement for flexible use - Durable flat carbide tip for long life; optional spherical steel tip adds contact option - Small, handheld design suitable for on-site or workshop use Use scenarios - Electronics assembly and component placement: set a baseline with zero at a chosen position and measure gaps or thicknesses precisely - Fixture setup and machine alignment: establish a reference quickly, then fine-tune with incremental readings - Quality control and part inspection: verify dimensions during production using either absolute or incremental mode
