Vernier Tech Info Library TIL #1224

Question

What is the input impedance of a LabPro voltage probe?

Answer

The input impedences of our voltage probes are all listed on in the LabPro Technical Reference Manual. For a normal VP-BTA voltage probe used with LabPro:

Input impedance: +/-10V input 1M

Note that if one was to use a VP-DIN on a LabPro (via adapter) the input impendance would be:

Input impedance: 0 �5V input >10M

For the input impedance of the Differential Voltage Probe, see TIL 1428: Differential Voltage Probe Detail Information.
