Quick Start: Vernier Graphical Analysis® and Bluetooth®

  1. Turn on your sensor by plugging it into the AC power adapter. The Bluetooth® LED will blink red.
  2. Launch Graphical Analysis, then click Sensor Data Collection.
  3. Select your sensor from the list. The sensor ID is located on the sensor label near the bar code. Note: If you don’t see a list of available sensors, click WIRELESS. After selecting your sensor, click Pair.
  4. Click DONE. You are now ready to collect data.

How the Sensor Works

The Go Direct Constant Current System is a DC-coupled amplifier capable of delivering up to 0.6 A at 5 V DC. A current-sensing resistor allows monitoring of the output current by the data-collection software.

Current Conventions

The current will be indicated as positive if current flows from the positive (red) terminal to the negative (black) terminal as described by conventional current flow notation. Using electron flow notation, electrons flow out of the negative terminal through the circuit back to the positive terminal. The negative terminal is connected to ground via a power transistor and 0.1 Ω sensing resistor. The positive terminal connects to a 5 V power supply. The Constant Current System dial can be tuned to deliver up to 0.6 A with the voltage adjusting automatically (max 5 V). If the electrolyte resistance is too high, the 0.6 A may not be attained before the maximum of 5 V is reached.
