4.1 Specific Testing Functions
4.1.1 Loop Test
The KEW 6516 performs loop impedance tests with high accuracy, offering a 0.001Ω resolution. It features Anti-Trip Technology (ATT) for L-PE testing on all RCDs without tripping them. This function is available with both 2-wire and 3-wire connections, which is particularly useful in installations without a neutral line (e.g., 3-phase motor lines). The Zs Limit function compares measured values against standard requirements.

4.1.2 RCD Test
Test various RCD types including AC, A, F, B (General & Selective), and EV, as well as variable RCDs. The tester supports single and auto test modes, ramp tests, and contact voltage measurements.
4.1.3 Earth Resistance Test
Conduct 2-wire and 3-wire earth resistance tests. All necessary accessories for these tests are included with the instrument.
4.1.4 Insulation Resistance Test
Perform insulation resistance tests at 100V, 250V, 500V, and 1000V. The device features an auto-discharge voltage function for safety.

4.1.8 SPD Test
Tests Surge Protection Devices (SPDs) that utilize varistors, determining their tripping voltage without causing damage.
4.1.9 PAT Test
Functions as a Portable Appliance Tester, performing insulation and protective conductor resistance tests for portable appliances.
4.1.10 PSC/PFC Testing
Measures Prospective Short Circuit Current (PSC) and Prospective Fault Current (PFC).
4.1.11 Frequency Testing
Measures the frequency of the mains supply.
4.2 Connectivity
