Change test mode
Choose the measuring method you will use in the menu Change Test Mode.
There are three different methods to choose:
• Analysis Mode
• Detection Mode
• Combined Mode

Calibration
The instrument must be calibrated by using the integral calibration function to
ensure it displays the correct values in Analysis Mode/Combined Mode. After
calibration the instrument will show the correct measured values on the display.
The calibration parameters will be stored into the probe.
Figure C-5: Calibration screen example
Detection mode settings
In Detection Mode, the signal is displayed in the form of a bar. The length of
the bar varies with the gas concentration.

Analysis mode settings
In Analysis Mode the measured value is displayed in figures. The default unit is
in PPM but it is possible to choose other units, See .“C 500 Factory configura-
tion of the leak detector parameters” on page 65
