4.3 Menu CHANNEL – Parameters and Functions
The channel menu shows channel number, transducer type and the associated
parameters and functions which directly affect pressure reading.
Confirm changes and switch to the next parameter
(flashing inversely)
Adjust input value by means of the up/down keys.
ch: Select channel number
type: Transducer type (cannot be edited)
corr: Set gas type correction factor
For transducers whose measurement depends on the type of gas you
can enter a correction factor for compensation. This way the pressure
reading can be corrected in a range below 0.1 mbar.
Appropriate correction factors are found in the operating instructions
of the transducer or suitable technical literature. The range of the gas
type correction factor is 0.20 to 8.00.
For transducers with combination sensors separate factors for both
sensors can be entered. The associated sensor type is displayed in
superscript letters behind the numeric value of the factor, e.g. PI for
Pirani, CC for Magnetron (cold cathode) and BA for Bayard Alpert (hot
cathode). Alternatively you can select pre-defined gas types from a
list.
