Notes for input impedance:
1 For 5 V to 1000 V range, the specified input impedance in parallel with 10 MΩ at dual display.
2 The specified input impedance (nominal) in parallel with <100 pF.
3 For 5 V to 1000 V range, the specified input impedance is in parallel with 10 MΩ when the input voltage is >+3 V or <–2
