Chapter 2 Working with DaqLab
Measure two reference values
Before taking measurements you need to disable the temperature compensation both in
DaqPRO
and in the calibrator.
To disable the temperature compensation in
DaqPRO
:
Click
Logger
on the menu bar, point to
Thermocouple Compensation
, and then click
Disable
.
Note:
Don
’
t forget to enable the temperature compensation prior to normal operation of
DaqPRO
. One
way to enable the temperature compensation is to turn
DaqPRO
off and on again. Another way is via
DaqLab: Click
Logger
on the menu bar, point to
Thermocouple Compensation
, then click
Enable.
To take two reference measurements
Measure two known reference values and record both the reference values and the values displayed by
DaqLab. Calculate the offset values.
The offset value is the difference between the value displayed by
DaqPRO
and the reference value. For
example, if the calibrator is set to 0
°
C and
DaqPRO
reads 1
°
C the offset value is
+
1, but if
DaqPRO
reads
−
1
°
C then the offset value is
−
1.
Enter the offset value
a. Connect
DaqPRO
to the PC.
b. Click
Logger
on the menu bar, then click
Calibration >
Calibrate Sensors.
c. Enter the calibration password, then click
OK.
d. Choose a sensor from the
Select sensor
drop-down menu and click
OK
to open
the
Sensor calibration
dialog box:
