Using the Product
Connect the sensor following the steps in the Getting Started section of this user manual.
Go Direct Voltage is designed to be used like a voltmeter. The leads should be placed across a circuit element. Go Direct Voltage has two measurement ranges, each its own channel:
- Potential - 20 V
- Potential - 1 V
Potential - 20 V
This channel is the default for Go Direct Voltage and appropriate for most table-top circuit experiments. The differential input range is 20 V. When used by USB, the mean input voltage must be within 11 V of ground.
Potential - 1 V
This extra channel is for appropriate smaller voltage signals, such as the induced EMFs. The differential input range is 2 V.
Over-voltage protection is provided so that slightly higher input voltages will not damage the sensor. You should never use high voltages or household AC with this probe.
Click or tap the view icon and select Meter. The instantaneous sensor readings are all displayed. Click or tap any meter to zero or calibrate that sensor.
Click or tap the view icon and choose the number of graphs you wish to display. For each graph, click or tap on the y-axis label to select which sensor data you would like displayed on that graph. Change data collection parameters (duration, sampling rate) by clicking or tapping on graph options. When ready to collect data, click or tap collect.
Care and Maintenance
Clean sensor with a soft, damp cloth.
Go Direct Voltage contains a small lithium-ion battery. The system is designed to consume very little power and not put heavy demands on the battery. Although the battery is warranted for one year, the expected battery life should be several years. Replacement batteries are available from Vernier (order code: GDX-BAT-300).
Storage and Maintenance
To store Go Direct Voltage for extended periods of time, put the device in sleep mode by holding the button down for at least three seconds. The red LED will stop flashing to show that the unit is in sleep mode. Over several months, the battery will discharge but will not be damaged. After such storage, charge the device for a few hours, and the unit will be ready to go.
Exposing the battery to temperatures over 35°C (95°F) will reduce its lifespan. If possible, store the device in an area that is not exposed to temperature extremes.
Go Direct Voltage is not water resistant and should never be immersed in water.
If water gets into the device, immediately power the unit down (press and hold the power button for more than three seconds). Disconnect the sensor and charging cable, and remove the battery. Allow the device to dry thoroughly before attempting to use the device again. Do not attempt to dry using an external heat source.
