What is a Digital Tension Gauge?
The DTG-100 is a portable digital tension gauge that measures the coupling tension between vehicle connector pins using a non-contact method.
■ Operating Principle
Detects changes in distance between Hall sensor (Hall Effect Sensor) and neodymium magnet
Measures changes in magnetic field strength to calculate tension values
■ Display Functions
Intuitive tension level display using a 5-step LED indicator
Auditory feedback of measurement results via buzzer notification
