Calibration Check (Cal Check)
NOTICE:
Cal Check Availability
Note: Cal Check is only available for helium (mass 4) testing in vacuum method
with the internal calibrated leak selected.
1.
Press the Calibrate Icon.
2.
In the Cal Type box, there are two options: Calibrate or Cal Check. Toggle the Cal
Type button to select Cal Check and press the Start button.
3.
The unit will proceed through the peak measure and background check sections of
a calibration cycle. The detector verifies the calibration reading is within 20% of
adjusted leak rate value.
4.
If the unit fails a Cal Check the user will be notified via a warning. See Calibration
History for results on both Cal Checks and calibration cycles.
6.4.1.3.
External Calibration
–
Vacuum Method
NOTICE:
External Vacuum Calibration Availability
The external vacuum calibration method is available for all test gas masses.
NOTICE:
External Calibrated Leak Settings
Verify the calibrated leak is within calibration and the correct calibrated leak
settings are entered. External leaks require the user to enter an estimated
calibrated leak temperature. LACO manufactured leak standards are very
temperature independent, so entering an average temperature of around
25 °C will work for most applications.
