Quick purging also enhances signal repeatability.
Note: Purge level interrupts active sampling of APC probes. This means that higher
signals will be underestimated as the sensor is purged before full signal has
developed.
Reset Signal
Reset the sensor signal in Measuring mode and Locating mode.
8.10 Display Settings
This section describes the different display settings of the Sensistor ISH2000.
Contrast
Contrast level of display. Higher value gives higher contrast. The contrast may need
adjustment if ambient temperature changes.
Brightness
Brightness of the display lamp.
Invert Colors
Change the black to white and white to black. Useful in a dark environment to keep
a high readability.
Screen Save Timeout
Display lamp will turn off if instrument is left idle for the number of minutes set by
this parameter. The screen save timeout can be set between 1 and 60 minutes, the
function is deactivated if set to OFF. The display lamp will return to the set
brightness if any of the display or probe buttons are pressed, if a gas signal is
detected or an instrument error is detected.
8.11 General Settings
This part describes the general settings of the Sensistor ISH2000.
Correlation Value
Correlation Value is used when it is necessary to correct the relation between the
detector signal and the displayed number. This might be necessary if the hydrogen
concentration of the Tracer Gas, inserted into the test object is changed, e.g. when
the Tracer Gas is mixed with existing air in the test object
