IMPORTANT
This page is only for models with date code prior to 0309.
Pre 0309 Date Code Jumper Settings
Input Signal
The C7232 Sensors have an adjustable range. These ranges
are determined by the SW2 and OUT1 jumper settings (see
Table 6).
NOTE: When choosing analog output, be sure to set the
SW1 jumper to the On position.

The analog output will not work properly when SW1 is Off.
d
When the level reaches this value, the contacts close; when the
level drops 100 ppm below this value, the contacts open.
Output Signal
The output signal can be adjusted for 0/2-10Vdc or 0/4-20mA
(see Table 7).
