OUTPUT MIDDLE RANGE
To easily adjust a recorder offset, the analog output could be set to middle range. In this case the
output is set to 5 mV, 50 mV or 500 mV for 0-10 mV, 0-100 mV or 0-1 V output and to 12 mA or
10 mA for 4-20 mA or 0-20 mA output.
To activate this option select “General Menu” - “Analog Output” - “Output Middle Range” function
and press CFM key. The analyzer will display “Recorder output is set to middle value”. Press ESC to
exit from this function.
For PCA340 to activate this option select “General Menu” - “Analog Output1” or “Analog Output2”
- “Output Middle Range” function and press CFM key. The analyzer will display “Recorder output is
set to middle value”. Press ESC to exit from this function.
Note: The analog output calibration is not allowed if the analog output type is set to “Dosing”.
Pressing for longer time the arrow keys will increase the variation speed of the analog output.
The PCA310 - PCA340 analyzers have a permanent logging function. Up to 3500 records could be
stored. At a sampling interval of 3 minutes the log covers more than 7 days.
If the logging memory is full, the oldest record is lost when a new record is stored.
The record contains the date and time, the chlorine, pH, ORP and temperature value and the status
of errors and alarms.
SET LOG
The data are stored after the chlorine measuring cycle is completed. The log could be performed
only after several chlorine cycle. The number of cycles between two logs are set in “General Menu” -
“System Log” - “Log Cl cycles”.
The allowed range is between 1 and 10 chlorine measuring cycles.
Example: If the sampling period for chlorine is set to 3 minutes and the log Cl cycles is set to 5,
a new record is stored at each 15 minutes (3 x 5).
