Lo-Z DCV threshold level:
<-1.0VDC or +1.5VDC< nominal
Lo-Z DCV input impedance:
Initial: Approx. 3.0kΩ, 270pF nominal; If a reading is over 50V
(typical), the input impedance goes up abruptly.
The followings are the final impedances by readings:
18kΩ for 100V
125kΩ for 300V
320kΩ for 600V
500kΩ for 1000V
