7.14 Analog
Enter setup of Analog. Select the function as for Free Cl
2
or pH, and then select as 0~20mA or
4~20mA current output. Set the related value to the range of Free Cl
2
/ pH measurement. If the range
of the 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, in order for convenience of insuring 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.
If select analog output corresponding to Free Cl
2
measurement, the procedure is as follow:
