In the menu "Units control" you can determine the switch point for the signal value from ppb to ppm, respectively from ppm to vol%. But, the set-ups in this menu are only operative for earlier versions of analyzers or analyzer modules. The switching will work automatically depending on the signal value for analyzers from the version 2.2 on.

Set up parameters:

¨Select any line of variables with the ↓ -key or the − -key.

¨Select the variable with the ENTER 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 ENTER key or cancel and go back to the last value with the F2 key.

Lines of variables "ppm to vol% switch point" and "PPB to PPM switch point":

In these lines you can determine which signal value shall switch the displayed concentration from ppb to ppm resp. from ppm to vol% (or reverse).

Line of variables "Hysteresis":

The value selected in this line will determine the range for the switching of the concentration unit.

Example:

¨Hysteresis is 10% and switch point ppm <–> vol% is 10000 ppm

¨The concentration value displayed will change with increasing signal values from ppm to vol% at: 11000 ppm, i.e. the concentration of 11000 ppm will be displayed as 1.1%.

¨The concentration value displayed will change with decreasing signal values from vol% to ppm at: 0.9%, i.e. the concentration 0.9% will be displayed as 9000 ppm.
