• Go to the line you want with the ↑↑ -key or the ↓↓ -key.
• Select the tag of the channel with the 88 -key or the →→ -key:
The display will go back to the menu "Analog Outputs" automatically.
The tag of the channel selected will appear in the line "Analyzer module".
3) Select the signal name:
• Change to the line "Signal name" with the ↓↓ -key
• Select the parameter with the 88 -key or the →→ -key and adjust one of the following
parameters with the ↑↑ -key or the ↓↓ -key:
„ Concentration
„ Average
„ Peak-Value
„ Temperature
„ Pressure
„ Flow
„ Range
„ Calculator-1
„ Calculator-2
„ Calculator-3
„ Calculator-4
• Confirm the parameter selected with the 88 -key.
4) Determination of the output signal values:
• You can determine the signal value for the 0% output and the 100% output in the lines
"Signal value for 0% output" or "Signal value for 100% output". So you have the
possibility to zoom out a certain part of the whole range.
• Example:
„ Range from 0 to 1000 ppm
„ 0% value shall be 400 ppm, 100% value shall be 700 ppm
„ Analog output is normally: 0V = 0 ppm 10V = 1000 ppm
„ After changing the output signal: 0V = 400 ppm 10V = 700 ppm
• Change to the line "Signal value for 0% output" or "Signal value for 100% output" with
the ↓↓ -key.
• Select the value 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.
• Confirm the new value with the 88 -key.
• Note:
If you change the measurement range, the adjustment done in this menu will dis-
appear and go back to the standard values of the range! To change the output signal
values permanently you have to change the adjustments in the menu "Begin and End
of Ranges" (see 5.1.3 p. 5-27)!
• Attention:
The signal range at the analog output should not be less than the littlest range!
Otherwise, the noise level may be very high at the analog output!
