➔ If AutoTest mode is set to Automatic, and Save Result is on, the finished test will
read Pass or Fail at the end of the test. When a new test is started, the text will
refresh to the current value.
➔ For data logging in either Test Summary or Test Stream and Summary methods,
the test result will read Pass or Fail depending on the final leak rate and the Reject
Limit setting.
Sniffer Probe Clogged When the leak rate exceeds the Probe Clogged Limit in Sniff Mode, the unit will issue a
warning to indicate clogged sniffer probe. Inspect sniffer probe when this occurs.
Gross Leak Setpoint The Gross Leak Setpoint parameter prevents excess tracer gas from contaminating the
detector. When this setting is enabled, and the leak rate exceeds the gross leak
setpoint, the test cycle stops automatically and returns to standby mode.
It is recommended to set the gross leak setpoint to a maximum of 4 decades above the
reject set point. This is setting is ideal for Inside-Out Vacuum applications where gross
leaks can be common.
Gross Leak Cleanup If a gross leak appears the above the setpoint, the unit will switch to Gross Mode and
pump to remove gross leak condition. In this condition, the detector can switch
between gross and ultra modes to help eliminate the high leak rate condition.
