Adjusting the High CO
The setpoint value is adjusted by closing jumper JP3 (see
Figure 2 on page 4). If the display is present when JP3 is
closed it will show the current high limit setpoint in ppm
CO
If there is no display this setting can be adjusted by using a
meter connected to the output. In this calibration mode the
analog output is 10,000 ppm at full scale (i.e. 10.0 volts or
20.0 mA). If the voltage output is selected, this scaling
corresponds to 1ppm per millivolt or 1 volt per 1000 ppm.
The setpoint is adjusted with the 'UP' and 'DOWN' buttons
while JP3 is closed. When JP3 is opened, the new relay
setpoint takes effect and is stored in non-volatile memory.
The setpoint hysteresis is approximately 40 ppm.
