This Voltage Input Phidget provides a way to
measure small voltages anywhere in a circuit. It plugs directly into
a VINT port and has a set of selecable voltage ranges from ±
1V down to ± 10mV, with smaller ranges having higher precision
(See the Comaptible Products tab for a list of VINT Hubs). This Phidget
also has an automatic mode that continuously adjusts the range based
on present voltage measurements, so you'll always have the most accurate
measurement possible.
Ideal for Use with Current Sense Resistors
You can use this Phidget to measure current in a pinch: Just place a known resistor in series with the circuit, and measure the voltage drop across it. Knowing the voltage and resistance, you can then use Ohm's law to calculate the current.
Isolated for Stability
This Phidget is electrically isloated, so a power surge on the circuit you're measuring will not damage your VINT Hub or your computer. Isolation also improves stability by eliminiating potential ground loops.
