3. Temperature Compensation
Use this option if you wish to use an external temperature probe to compensate for thermocouple
measurements.
If you choose the external compensation you must connect an NTC 10k temperature probe to input 1
and the thermocouple sensor to any other input, and then setup the device accordingly.
Check the Ext Compensation checkbox in step 2 of the Setup wizard.
4. Averaging
Use this option to reduce random noises. DaqPRO replaces every data sample with the average of the
last pre-set number of samples
To apply averaging:
Check the Averaging checkbox in step 2 of the Setup wizard, and select the number of samples to
average from the drop-down menu.
5. Battery Level
A battery level indicator is displayed in step 3 of the Setup wizard. The indicator shows the remaining
working hours as a percent of the battery’s life (approximately 25 hours between charges), before it
should be recharged.
6. Presetting the Display
You may want to define the graph’s settings, such as formatting and scaling the graph and selecting the
axes, and to define the meters’ settings prior to beginning a recording session. You can define the
settings of each sensor input individually in the first step of the Setup wizard:
