Thus, incorrect measurements are excluded! • Standard-compliant voltage testers must comply least with protection category 54. • Always check voltage testers for correct functioning immediately before and after use. • Please take into consideration the high-impedance input resistance (~10 MQ) digital multimeter which indicates capacitively and inductively induced voltages and which very often might only simu­ late the existence voltage.
