WebAlso, most of these high range multimeters actually have a much higher input impedance at low ranges. Of the top of my head, the Keithley 2000 has a rated input impedance of >10 GOhms for all but the two highest ranges (so up to 10 volts full scale). The range changes the gain of the amplifier, and doesn't use a input divider to scale. sieps shop winsumWeb28 de abr. de 2024 · A Hi-Z point is one connected to a very high resistance so no current can flow. In your schematic NO wire (neither of 1,2,3,4) is Hi-Z because if you connect one of them to GND, current starts flowing and the LED lights up.
