The "CBT-500 model" is a measuring device designed to accurately measure the resistance value of connected wires. It applies low voltage and high current in a pulsed manner to the wire being measured, allowing for precise measurement of the resistance value of the wire. Additionally, since it does not continuously flow current, there is no damage to the wire being measured. It can be used as a standalone resistance measuring device for the wire being tested, as well as a tester for measuring changes over time, providing GO/NG judgment. 【Features】 - Applies low voltage and high current in a pulsed manner to the wire being measured - Accurately measures the resistance value of the wire being tested - No damage to the wire being measured since current is not continuously flowing - Can be used as a standalone resistance measuring device for the wire being tested, as well as a tester for measuring changes over time, providing GO/NG judgment *For more details, please refer to the PDF document or feel free to contact us.
