Switching: Manual
Zoom: 50 %
Position: LowScale
Status: Off
This allows to increase the resolution (concen-
tration/mA) for a selected range of the entire
measuring range.
Note!
Zooming may affect the analog outputs
accuracy!
Carefully read the information, given
page 3-28 before scaling analog outputs!
X-STREAM analyzers support the zooming
of analog outputs with the following options:
The zoom function can be activated in different
ways; this is set in the “Switching” line:
• Manual
: The operator must activate the
zoom function manually, with either
• the “Status” parameter in the last line
of this menu
or
• a parameter in the CONTROL - ZOOM..
menu
• Auto
: The analog output is switched de-
pending on the measured concentration.
• Inputs
: This requires setting a digital
input. If an external signal is present at
that input, the analog output is switched.
In the second line of the menu the zoomed
area can be set to between 1 and 99 % of the
range previously set in the “LowScale” and
“HighScale” functions.
