1.3.3. pH Temperature Compensation
To compensate a pH sensor for temperature changes, plug the temperature sensor
into Input 1, and the pH sensor in Input 2. MultiLogPRO will then display the
compensated pH value.
1.3.4. DO
2
Calibration
To calibrate your DO
2
sensor with the right salinity and altitude parameters, use the
DO
2
Calibration command from the Configuration menu (see page 19)
1.3.5. MultiLab Sensor Calibration
The sensors can also be calibrated using the Calibrate Sensors option in MultiLab
’
s
Logger menu. Please refer to section 2.5.6 for more information.
1.3.6. Factory Calibration (No Calibration Required)
All digital sensors that are essentially timers leave the factory fully calibrated, and do
not suffer from any accuracy degradation. An example of such a sensor is the Sonic
Ranger distance sensor, which measures the time passed from the transmission of a
sound pulse to its echo reception.
