68 TITAN VERSA Operations and Maintenance Manual LACO Technologies
Test Method The two test methods for the TITAN VERSA are vacuum and sniff. Press the method
icon to toggle between the two desired settings and the press the Save button to save
the settings.
➔ See General Use Guidelines for application and theory on both Vacuum and Sniff
leak testing methods.
➔ Switching from Vacuum to Sniff test
After modifying the settings, a transition duration of <3 minutes occurs, during
which the test can be performed but calibration is not possible.
➔ Switching from Sniff to Vacuum test
After modifying the settings, a transition duration of 30 seconds occurs, during
which neither the test nor the calibration can be performed.
Vacuum Test Mode Table 29 outlines the three vacuum test modes and their various functions. Press the
Test Mode button to toggle between the three options. In most applications, Ultra
mode should be used as the final test mode.
➔ Note: When in sniff mode this parameter will be hidden.
Vacuum Test Mode Summary
Crossover Pressures As defined in Table 29 above, each vacuum test mode has a maximum pressure
crossover setpoint. In most applications the default crossover pressures should not be
adjusted.
➔ Note: These parameters are hidden when in Sniff mode.
➔ Skip Test modes. In certain applications it may be desired to skip certain test
modes. To enable skipping of test modes, enter crossover pressures smaller than
final desired test mode (see table below).
