Main circuit resistance tester

This is a device for measuring the contact resistance of the main contact part of a power circuit breaker. (1) Connect this product to the main circuit using the included cable, (2) turn the power switch ON, and (3) simply adjust to the desired current. It is portable, making it suitable for on-site work. ● The current can be varied up to a maximum of 100A (adjustable range: 50-105A). ● It can measure resistance up to a maximum of 1.999 mΩ. ● Open circuit voltage: DC 5V. ● Three display modes: resistance, current, voltage. ● Latest model of the ST series. There is no dedicated demo unit for the ST-102A, but you can try the operation feel with the ST-10A (10A type) demo unit. Demo units are available! We offer demo unit rentals for customers considering purchase. If you would like to "try the operation feel," "check if the settings can be easily made," or "confirm if the intended tests can be conducted," please request "demo unit desired" through the standard product inquiry form on our website. https://serizawa-sr.co.jp/contact-1
