accuracy. A low setting gives best accuracy but lower tolerance for “noise” gas
signals. The
Detector Signal Level is set as 1 to 100% of the Reject Level . Default is
20%.
NOTICE! Increasing the Detector Signal Level may give poorer accuracy.
Trigg Level
Upper Limit setting for Peak hold in analysis mode.
Minimum Calibration Time
Lower limit setting for the timer which is used during calibration. Contact INFICON
AB to have the code sent to you. See the web address under section-Info.
Battery Mode
Selection of battery power. Only used to adapt software for the battery model.
Number of Significant Digits
Choice of a number of significant numbers in Analysis and Combined Mode. It is
used when a more exact measurement is needed. A good control of the
environment and calibration is required to be useful. Contact INFICON AB to have
the code sent to you. See the web address under section-Info.
Debug Mode
This mode is used during service and software development.
Service Mode
This mode contains useful information to analyse the gas sensor behavior. If the
instrument starts in the Service Mode then it is possible to reach APC Service Mode.
Under APC Service Mode is useful information to check timers, I/O on the Probe
Control Port, and other.
8.11 Combined Mode
In Combined Mode the bar and the sound in Detection Mode is combined with the
figures in Analysis Mode , this means that at the same the signal is displayed as a bar
and the measured value is displayed in figures.
The loud speaker sound follows the Detection Mode signal.
Note: After a system reset the default mode is Combined Mode .
When you have located the leak then you can measure its size in the following way:
1. Remove the probe from the leak.
2. Wait until 0.0 appears on the display
3. Then put the tip of the probe on the leak.
8.12 Probe
The hand probe P50 is a non-sniffing probe. Gas analysis takes place in a sensor that
is in the tip of the probe. The probe is equipped with a function button, indicator
lamps, and lighting. Also the probe can be ordered with a flexible neck.
