1. The following statements are true for earth-bond resistance tests:
– Overload protection: < 2 V and 0.44 A/1000 V; 10 × 35 mm 30 kA fast-acting fuse
– Short circuit: > 200.0 mA as resistance ≤ 2 Ω
2. The accuracy is speciied after the Null function is used to subtract the test lead resistance and thermal effect (by shorting the test leads)
