Measurement units depend on the selected sensor. For example, units for the Vernier Go!Temp® Temperature sensor are Fahrenheit, Celsius and Kelvin. Units for the Vernier Hand Dynamometer (a specialised force sensor) are Newton, Pound and Kilogramme.

You can change the units before or after you collect data. The collected data reflects the new measurement unit.

1.

Click Meter view  to display the connected and offline sensors.

2.

Click the sensor whose units you want to change.

3.

In the Meter Settings dialogue box, select the unit type from the Measurement Units menu.

 

When the software or handheld detects a sensor, the calibration for that sensor automatically loads. You can calibrate some sensors manually. Other sensors, such as the Colorimeter and the Dissolved Oxygen Sensor, must be calibrated to provide useful data.

There are three options for calibrating a sensor:

•

Manual Entry

•

Two Point

•

Single Point

Refer to the sensor’s documentation for specific calibration values and procedures.

 

You can set the standing value of some sensors to zero. You cannot set sensors in which relative measurements such as force, motion and pressure are common to zero. Sensors designed to measure specific environmental conditions, such as Temperature, pH and CO2 also cannot be set to zero.

1.

Click Meter view  to display the connected and offline sensors.

2.

Click the sensor that you want to set to zero.

3.

In the Meter Settings dialogue box, click Zero.

 

By default, pulling with a force sensor produces a positive force and pushing produces a negative force. Reversing the sensor allows you to display pushing as a positive force.

1.

Click Meter view  to display the connected and offline sensors.

2.

Click the sensor that you want to reverse.

3.

In the Meter Settings dialogue box, click Reverse Readings.

The sensor display is now reversed. In Meter View, the reverse indicator appears after the sensor name.
