Set the "Background Timer"
Activate/Deactivate the "External Trigger"
Select the "Rejection Type"
Delay Timer In order to prevent the evaluation of fluctuations of the leakage rate signal
after switching the sensitivity range (e.g. to ULTRA), you can set the "Delay
Timer". The "Delay Timer" starts when the most sensitive measurement
range is reached (see Chapter 4.3: "Technical Data", page 10). The test se-
quence continues only after the set time elapses.
In addition, you can use the "Delay Timer" to specify a minimum time for the
test sequence.
1. Select " Setup > Auto Test > Auto test timer".
2. Define your settings for the "Delay Timer".
Test Timer The response time of the leakage rate signal depends on the volume in the
test chamber as well as the pumping speed of the T
ITANTEST™.
A partial flow pump can be used to complement the pumping speed of the
T
ITANTEST™ if necessary (see "Setting the Ext. Pump Setup", page 37).
1. Select " Setup > Auto Test > Auto test timer".
2. Enter the desired measuring time under "Test Timer".
Select the measuring time in such a way that the leakage rate signal
increasing over time differs clearly from the background signal.
Background Limit In order to prevent incorrect measurements due to a high tracer gas back-
ground, set the "Background Limit". The T
ITANTEST™ will not start the mea-
surement before the background signal falls below the set "Background
Limit".
1. Select " Setup > Auto Test > Auto test parameters".
2. Select a "Background Limit".
The "Background Limit must be lower than the setpoint.
If you do not require monitoring of the background, set a very high val-
ue for the "Background Limit". This may be the case when measuring
bombed test objects, for example.
Background Limit Timer This timer limits the time the TITANTEST™ waits for the background limit. If
this timer is excceded, the TITANTEST™ will stop the AutoTest cycle with
warning message 163 error message.
1. Select "Setup > Auto Test > Auto test timers".
2. Define your settings for the "Background timer".
External Trigger If you want to fill the test object with tracer gas, you can trigger a gas filling
station via an output of the T
ITANTEST™ (pin 20 on the D-sub plug). To do this,
you must enable the external trigger:
1. Select " Setup > Auto Test > Auto test parameters".
2. Select "External Trigger" and set the value to "enabled".
After the "Background Limit" is reached, the device activates the PLC
output (pin 20 on the D-sub plug).
