The VCP1002 can be used to measure small voltage values up to ±1V. This Phidget connects to your computer through a VINT Hub.
This Phidget is a smart device that must be controlled by a VINT Hub. For more information about VINT, have a look at the VINT Primer. You can use a Phidget Cable to simply and easily connect the two devices. Here's a list of all of the different VINT Hubs currently available:

|HUB5000_0||$60.00||6||Local Network (Ethernet or Wi-Fi)|
Use a Phidget cable to connect this device to the hub. You can solder multiple cables together in order to make even longer Phidget cables, but you should be aware of the effects of having long wires in your system.
Welcome to the VCP1002 user guide! In order to get started, make sure you have the following hardware on hand:
Next, you will need to connect the pieces:
Now that you have everything together, let's start using the VCP1002!
In order to demonstrate the functionality of the VCP1002, the Phidget Control Panel running on a Windows machine will be used.
The Phidget Control Panel is available for use on both macOS and Windows machines.
To open the Phidget Control Panel on Windows, find the icon in the taskbar. If it is not there, open up the start menu and search for Phidget Control Panel
To open the Phidget Control Panel on macOS, open Finder and navigate to the Phidget Control Panel in the Applications list. Double click on the icon to bring up the Phidget Control Panel.
For more information, take a look at the getting started guide for your operating system:
Linux users can follow the getting started with Linux guide and continue reading here for more information about the VCP1002.
After plugging the VCP1002 into your computer and opening the Phidget Control Panel, you will see something like this:
The Phidget Control Panel will list all connected Phidgets and associated objects, as well as the following information:
The Phidget Control Panel can also be used to test your device. Double-clicking on an object will open an example.
The VCP1002 allows you to measure voltages up to ±1V. This Phidget is ideal for small voltage monitoring applications. You can manually select the voltage range (±1V down to ±10mV) in your program to maximize resolution, or use Automatic mode which constantly adjusts the range based on the last voltage measurement.
You can use your Control Panel to explore your Phidget's channels.
1. Open your Control Panel, and you will find the 10-bit (+-1V) Voltage Input Phidget channel:
2. Double click on the channel to open an example program. This channel belongs to the Voltage Input channel class:
In your Control Panel, double click on "10-bit (+-1V) Voltage Input Phidget":
Before you open a Phidget channel in your program, you can set these properties to specify which channel to open. You can find this information through the Control Panel.
1. Open the Control Panel and double-click on the red map pin icon:
2. The Addressing Information window will open. Here you will find all the information you need to address your Phidget in your program.
See the Phidget22 API for your language to determine exact syntax for each property.
The Change Trigger is the minimum change in the sensor data needed to trigger a new data event. The Data Interval is the time (in ms) between data events sent out from your Phidget. You can modify one or both of these values to achieve different data outputs. You can learn more about these two properties here.
The VCP1002 is electrically isolated. A power surge in the circuit being measured would only affect the VCP1002, so your VINT Hub or computer will remain unharmed. Having isolation also helps prevent the formation of ground loops in your system.
With isolation on the VCP1002, you can measure the voltage differential between two points of a circuit regardless of their relation to ground. The voltage differential between those points must be within the specification of the sensor.
For example, in the pictured battery charging circuit, there is sufficient complexity between the current sense resistor (Rsense) and VINT Hub that directly measuring the voltage with a non-isolated sensor could be a risky proposition. However, with VCP1002, the voltage across the resistor may be measured directly, ignoring the circuits in between.
The VCP1002 is made to measure small voltages anywhere in a circuit. As a result, the VCP1002 is ideal for use with current sense resistors to measure current. For an in-depth look at how to use current sense resistors with the VCP1002, see our article about Current Sense Resistors.
