【Purpose】 This is used to inspect the wiring condition of equipment and devices (to check for the presence of miswiring, wiring omissions, disconnections, etc.), and it serves the same purpose as the wiring inspection previously conducted with a bell checker. 【Conventional Bell Checker】 - It is necessary to run test wiring. - It cannot detect ground faults (contact with the chassis) along the way. - It cannot perform pair checks on twisted pair wires. 【Features of HWC200 Wiring Continuity Checker】 Unlike the conventional bell checker, it has the following features: (1) Wiring inspection (continuity check) between two distant points using a master/slave configuration does not require test wiring. (The earth side utilizes the chassis or casing.) (2) Ground faults (contact with the chassis or casing) in the wiring can be detected. (3) The continuity resistance value of the tested wire can be determined in stages. (4) In addition to a buzzer sound, visual confirmation is possible. (5) Double-checking is possible with two people at both ends. (6) Pair checks on twisted pair wires can be easily performed. (During pair checks, the negative side is connected to one side of the pair wire instead of the chassis.) 【Usage Examples】 (1) Examples of use with parent unit/child unit pairs Trains, automobiles, cranes, construction machinery, elevators, escalators, factory equipment, steel structure buildings, etc. *Since the chassis is used as a ground wire, it can be used regardless of genre as long as the chassis is conductive. (2) Example of standalone use of the parent unit Any equipment or device, similar to conventional bell checkers. Additionally, if the chassis is conductive, it is also possible to detect whether there is contact with the chassis.
■ No long wires are needed for wiring continuity checks, improving work efficiency (using the casing) ■ Capable of detecting ground faults in the wire (contact with the casing) ■ Buzzer sound and LED display ■ Double-checking possible with two people at both ends ■ Usable as a conventional bell checker with just one unit ■ Users can change the threshold ■ Automatic recognition of modes (master/slave/standalone) ■ Auto power-off function 【Usage Examples】 (1) Examples of use with parent unit/child unit pairs Trains, automobiles, cranes, construction machinery, elevators, escalators, factory equipment, steel frame structures, etc. *Since the chassis can be used as a ground wire, it can be used regardless of the genre as long as the chassis is conductive.
