the sample gas is drawn through the
measurement channel of the chip.
The chip parameters
measuring range)
measuring are displayed alternately.
The maximum measuring time is indicated in
brackets (> <). The passage of time is
indicated by the bars.
The actual measuring time depends on the
chip and on the concentration of hazardous
gas in the air.
A higher concentration yields a shorter
measuring time.
Example for the ammonia chip (6406020):
approx. 1 minute measuring time
at 25 ppm NH3
approx. 3 minutes measuring time
at 5 ppm NH3
Note the Instructions for Use of the selected
chip.
The measured value is displayed.
