TD1400 Series Loop Resistance Tester
TD1400 Series Loop Resistance Tester is a device specially used to measure the loop resistance or contact resistance of high and low voltage switches, copper and aluminum busbars. This device fully complies with the "JJG 1052-2009 Loop Resistance Verification Regulation" and "DL/T 845.4-2004 General Technical Conditions for Resistance Measuring Devices".
Features:
1 TD1400 Series Loop Resistance Tester utilizes a precision DC constant current source, capable of providing up to 200 A DC current output.
2 This device is suitable for measuring low resistance values such as the contact resistance of main contacts in high and low voltage switches, and the DC resistance of high and low voltage cable lines; measurement range 0.0010 mΩ ~ 180.00 mΩ, with 5-digit resistance display and high accuracy class of 0.2.
3 It can operate normally in environments from -20 ℃ to 45 ℃ and with supply current within the range of AC ( 198 V ～ 253 V ).
4 Supports RS232 interface, enabling data storage, printing, and remote transmission functions.
5 Compact size, light weight, and easy to carry; built-in micro printer, very suitable for on-site measurement and direct report generation.
