Field Adjustments
This section describes the features that can be field
configured and the procedures to make these changes.
Analog Output Range Adjustment
I-310e. 2000 ppm users need not perform this adjustment.
The Model I-310e ships from the factory set for an analog
output range of 0 to 2000 ppm. This range can be changed
to any sub-range between 0 and 5000 ppm by changing two
parameters:
For example, a particular application may require the analog
output to remain at 0V or 4.0 mA until the gas concentration
reaches 500 ppm, then reach 10V or 20 mA at a
concentration of 1000 ppm. In this example the analog
output would scale across this 500 ppm sub-range so that the
analog output would be at half scale (5V or 12 mA) at
750 ppm.
To change the analog output range use the following
procedure:

The low output threshold is the concentration at which
the analog output will begin to rise. The factory default
low output threshold value is 0.
The high output threshold is the concentration at which
the analog output reaches its maximum value. The
factory default high output threshold value is 2000.
1. Note whether the shorting block at jumper JP5 is
covering both pins or only a single pin, then borrow
the shorting block and slide it over the two pins of
jumper JP4 (see Figure 2 on page 4). The display (if
present) will show 'SEL'.
2. The display (if present) will show 'SEL'.
Momentarily closing a jumper selects which value to
change. If the wrong jumper is selected simply open
JP4 to restart the unit and begin again.
