In the menu "General Concentration Measurement Setup" you can set up for the current
channel of an MLT analyzer or analyzer module the following parameters:
♦ the sample gas unit
Options: ppb, ppm, %, µg/Nm
3
, mg/Nm
3
, g/Nm
3
, %LEL, %UEL
♦ the "ppm →→ mg/Nm
3
" conversion factor
Options: 0 to 1000000
Note: The "ppm" →→ "mg/Nm
3
" conversion factor depends on the sample gas which is
used. The set-up is necessary if you want to display sample gas values in "mg/Nm
3
" !
♦ the lower explosion limit (LEL) and the upper explosion limit (UEL)
Options: 0 to 100%
♦ the measurement output during failure
Options: Actual, 0.0 V, End of range.
Set up parameters:
♦ Select any line of variables with the ↓↓ -key or the ↑↑ -key.
♦ Select the variable with the 88 -key or the →→ -key.
♦ Select any digit with the ←← -key or the →→ -key and adjust a new value with
the ↑↑ -key or the ↓↓ -key
resp. select the whole parameter with the ↑↑ -key or the ↓↓ -key.
♦ Confirm the new value with the 88 -key or
cancel and go back to the last value with the F2 key.
