Calibrating a sensor
When a sensor is detected, it automatically loads a calibration for that
sensor. You have the option of calibrating sensors. Some sensors cannot
be calibrated, while other sensors, such as the Colorimeter and the
Dissolved Oxygen Probe must be calibrated to be useful.
There are three options when calibrating a sensor:
•
Manual Entry
•
Two Point
•
Single Point
See your sensor’s specifications for information on the calibration values
and procedures to change.
Zeroing a sensor
Not all sensors can be zeroed. Sensors where relative measurements are
common, such as Force, Motion, and Pressure, can be zeroed. Sensors
designed to measure specific environmental conditions, such as
Temperature, PH, and CO
2
cannot be zeroed.
To set the standing value to zero:
³
Select
Experiment > Set Up Sensor > Zero
.
The sensor value is now at zero.
If more than one attached sensor can be zeroed, you will see a list of
sensors to chose from along with an option to zero all sensors.
Reversing a sensor
Use this feature to change the display of the reading.
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.
If more than one sensor can be reversed, choose the one to reverse from
the provided list.
To reverse the sign of the sensor reading:
³
Select Experiment > Set Up Sensor > Reverse
.
The sensor sign is now reversed. If you are in Meter View, you can see
the reverse indicator “
” after the sensor name.
