China 200A Portable Micro Ohm Meter Loop Resistance Contact Resistance 50A 100A 150A 200A Circuit Breaker Tester for High Voltage Switchgear Touch Scr

General Information:
The EPRC Micro Ohmmeter is a high-precision, digital switch detection instrument which conforms to the IEC standards. The instrument uses high-power constant-current switching power supply technology to measure micro-ohmic contact resistance. It is widely used for measuring the contact resistance, loop resistance of various switches and electrical appliances, and the contact resistance of cables, wires, and welds.
Features: It has multiple protection functions such as back-EMF impact, test line interruption, power failure, and overheating of the power supply. It can reliably protect the back-EMF impact on the instrument and sound the alarm synchronously.Intelligent power management technology, the instrument always works in the minimum power state, effectively saving energy and reducing heat.The output voltage is high and the measurement range is wide.The test current comes from a high-precision high-current constant-current power supply. No need manual adjustment is required, and the test is quick and accurate.The four-terminal wiring method effectively eliminates the influence of test line resistance on the test results.Seven-inch high-brightness touch color LCD, clear display under strong light, full touch screen operation.Perpetual calendar clock and power-off storage, which can store 1000 sets of test data, which can be consulted at any timeBluetooth communication, RS232 communication and USB interface for computer communication and U disk data storage.Built-in micro printer.
