3. CBL 2 and LabPro interfaces cannot be used with TI-84 Plus CE calculators.
4. DataMate cannot be used with color screen TI-84 Plus calculators; use EasyData with these calculators.

1. Plug the sensor into the interface (LabQuest 3, LabQuest Mini, etc.).
2. Connect the interface to your device.
   • If using USB, connect to the USB port on your computer.
   • If using Bluetooth^® wireless technology, click your interface type and then select your device.
3. Prepare for data collection:
   • Vernier Graphical Analysis^®: Launch the app, if necessary, and click Sensor Data Collection.
   • LabQuest^® App: Choose New from the File menu.

The software will identify the sensor and load a default data-collection setup. You are now ready to collect data.

You should not have to perform a new calibration when using the 30-Volt Voltage Probe in the classroom. The sensor will normally be automatically recognize and the proper calibration will be loaded. We have set the sensor to match our stored calibration before shipping it. To improve the accuracy, you have a couple of options. (1) Simply use the data-collection software to zero the sensor. (2) Use the software to perform a two point calibration. This method is especially useful if you want to accurately measure voltage over a narrow range.

30-Volt Voltage Probe range	±30 V
Resolution	15 mV
Supply voltage	5 VDC
Supply current (typical)	0.2 mA
Input impedance	30 kΩ
Output voltage range	±10 V
Calibration	slope: 3.0 V/V intercept: 0

Do not wrap the cable tightly around the sensor for storage. Repeatedly doing so can irreparably damage the wires and is not covered under warranty.

The 30-Volt Voltage Probe uses an internal voltage divider made up of a 10 kΩ resistor in series with a 20 kΩ resistor. The input voltage is applied across this voltage divider and the voltage drop over the 10 kΩ resistor is sent to the +/‑ 10 volt input of the interface. The resulting voltage is then multiplied by 3 for proper calibration.

There are zener diodes between the input and ground lines. These zener diodes will block voltages above 30 volts.

There is a resettable fuse on the ground line of the 30‑Volt Voltage Probe that will open if any significant current is drawn on that line. This could happen, for example if you were using it on a grounded interface, with a grounded power supply, and the ground lead was connected improperly to a voltage above ground potential.

Vernier produces a number of different voltage probes, each with different ranges and characteristics:

Voltage Probe (VP-BTA), Range: –10 V to +10 V. The Input Impedance is equal to the input impedance of the interface. This sensor has grounded inputs. This means that the ground (black) lead is connected to the ground of the interface. Keep this in mind when using two of these sensors connected to the same interfaces. VP‑BTA reads a non‑zero voltage when the leads are not attached to anything. This can cause confusion to novice users.

30-Volt Voltage Probe (30V-BTA), Range: –30 V to +30 V, Input Impedance = 30 kΩ. This sensor has grounded inputs. This means that the ground (black) lead is connected to the ground of the interface. Keep this in mind when using two of these sensors connected to the same interfaces. The sensor reads a near-zero voltage when leads are not attached to anything.

Differential Voltage Probe (DVP-BTA), Range: –6 V to +6 V, input impedance: 10 MΩ. Differential input means that the ground (black) lead is not connected to the ground of the interface. Multiple DVP‑BTA sensors can be used while connected to the same interface, without “common ground” confusion. The DVP‑BTA sensor reads zero volts when leads are not attached to anything.

Go Direct Voltage Probe (GDX-VOLT), Range: –20 V to +20 V, input impedance: 10 MΩ. This sensor has differential input, which means that the ground (black) lead is not connected to the ground of the interface. Multiple GDX-VOLT sensors can be used while connected to the same interface, without “common ground” confusion. The GDX-VOLT sensor reads zero volts when leads are not attached to anything.
