6.10 Analog output 1 (pH/ORP)
Enter setup of Analog 1. Select 0~20mA or 4~20mA current output. Set the related value to the
range of pH/ORP measurement. If the range of the pH/ORP measurement is to be set smaller, the
resolution of current output is higher. When the measured value exceeds the higher range limit, the
current will remain approximately 22mA output. When the measured value exceeds the lower range
limit, under 0~20mA mode the current output will remain 0mA output; while under 4~20mA mode
the current output will remain approximately 2mA output. The exceptional output value can be
used as a basis for failure determination. Under HOLD(measurement) status, the current output
maintain the last output value before HOLD status. However, to ensure the current setting of an
external recorder or of a PLC controller, the current output will be 0/4mA or 20mA under the
analog output setup menu.
