DSCN-101A: Power Cable Checker

DSCN-101A: Power Cable Checker

Measurement and diagnosis of the ground resistance of ME equipment and the resistance of the power cord.

This is a checker that allows anyone to easily test whether the ground resistance value of a 3P cable for medical devices is within the standard (below 0.1Ω). *Please refer to "JST T0601 (Corresponding International Standard IEC 60601-1)" for the standards. The power cable checker has the following functions: 1. Resistance diagnosis of the power cord 2. Ground resistance diagnosis of equipment where the power cord cannot be removed 3. Resistance diagnosis of 3P power strips By measuring resistance, you can confirm whether there are any contact failures or disconnections in the power cord, and check for the risk of electric shock (micro-shock). If you try to measure the resistance value of the power cord with commercially available testers, it can be quite labor-intensive. By using the power cable checker, even those without specialized knowledge can easily and accurately measure resistance. Additionally, since it is battery-operated, it can be used anywhere, and measurements are completed in about 10 seconds, so it doesn't take much time. We also offer demo units for loan. Please feel free to contact us.
