Display Indications and Control Elements 5.0 Display Indications and Control Elements Display Indications 1. Attention, warning symbol 2. “Limit”: exceeding the threshold value 3. “UB>UL”: contact voltage present exceeds the pre-set limit (25V or 50V) 4. “Temp”: internal temperature protection has triggered 5.
Carrying out Measurements 6.0 Carrying out Measurements 6.1 Loop Impedance Measurement / Short-Circuit Current Measurement Prior to any measurement, test the instrument for perfect functioning by using a functional Connect the mains lead to the mains connector EUT. This could be a correctly wired socket of (13).
