Actual output voltage: 100% ~ 120% of Test Voltage.
Live Circuit Detector: Inhibit test and display voltage reading instead if terminal voltage >
30 V prior to initialization of test. Display voltage accuracies:
 DCV: 1,5% + 5d.
 ACV: 3,0% + 5d @ 50 Hz ~ 60 Hz (unspecified @ > 600 Vac).
Specified measuring range is 0,020 MΩ ... 25,0 GΩ for percentage operating
uncertainty B[%] ≤ ±30% per IEC/EN61557-2 requirements.
