Detector Signal Level
The Detector Signal Level is the level which the sensor is considered to have recovered
from the last gas signal. It decides when the DET_SIGNAL output will come on. this
signal can be used to block the start of a calibration or new test cycle in semi and
fully automatic testers.
IF DET_SIGNAL is high then this means that the sensor has detected hydrogen and
has not yet recovered.
Detector Signal Level can be adjusted in the Service Settings menu . You can increase
Detector Signal Level if you have many small disturbing signals. A high setting of
Detector Signal Level gives better tolerance to “noise” gas signals at the expense of
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 .
Note: Increasing the Detector Signal Level may give poorer accuracy.
Trigg Level
Upper Limit setting for Peak hold in Measuring Mode.
Min 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.
Calibration Tolerance
The maximum difference between the different calibration measurements to
approve a calibration.
Battery Mode
Selection of battery power. Only used to adapt software for the battery model.
ILS500 Mode
This mode is used to adapt the ISH2000 for use into Leak Detector System ILS500.
Combine Mode and Printer Port is not available when ILS500 Mode is active. ISH2000
always start in Measuring Mode at startup.
Number of Significant Digits
Setting of significant numbers in Measuring and Combined Mode. It is used when a
more exact measurement is needed. A good control of the environment and
