73 series high current grounding resistance tester

● Current output range of 73 series AC grounding impedance tester is 1~60A

● All series of built-in special linear constant current output amplification lines

● Large 128 * 64 LCD; LCD display

● 7314/7316 single machine can be compared with 7100 series (7130/7132/7140/7142)

Connection of withstand voltage/insulation impedance tester

● Built in 10 groups of program memory, each group of 3 test steps can be programmed

Step 1 connection test

● Power on self-test function, which can check whether various functions of the instrument are normal before testing

● Test the line impedance self zeroing correction function to ensure the accuracy of the test

● Front panel software input correction
