9. If the unit fails a calibration, the user will be notified. See Calibration Settings for
more information on reviewing calibration results.
10. Remove calibrated leak valve from test inlet port.
6.4.1.4. External Calibration – Sniff Method
NOTICE: External Sniff Calibration Availability
The external sniff calibration method is available for all test gas masses.
NOTICE: External Sniff Calibration Availability
Verify the calibrated leak is within calibration and that the correct calibrated
leak settings are entered. External leaks require 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.
Sniff calibrations do not require a valve on the calibrated leaks standard.
Contact LACO for the industry’s largest selection of calibrated leak standard
options.
1. Set Calibrated leak type to External.
2. Insert sniffer probe into sniff test port inlet.
3. Use a sniff calibrated leak standard. This type of leak standard is different than
other vacuum-style calibrated leaks in that the leak element is built directly on the
end the calibrated leak element.
4. Place the sniffer probe into the calibrated leak inlet port.
