An isolated 4-20 mA recorder output is provided. The output also can be adjusted to
0-20 mA, and with the addition of a resistor across the recorder output lines, can be setup
as a 0 to 100 mV, 0 to 1 V, or 0 to 10 V voltage output. See Section 5.6.4 Recorder and
Controller for resistor installation. The recorder can be set to cover any portion of the pH,
