Converter's Functions:
Display Function:
Data: LED display – turbidity, lamp voltage, turbidity element detecting
current, reference element detecting current, analog output in %,
analog output in mA, zero point error and slope.
Operation status: Lamp – <MEAS.>, <MAINT>, <PROGRAM 1> and <PROGRAM 2>
modes.
Indicator – output signal, HOLD, CAL, WASH, FAIL
Instrument status: Indicator – lamp and each solenoid valve.
Maintenance Functions (<MAINT.> mode):
Zero calibration, shift calibration, span calibration, sensitivity correction
calibration, manual start of auto cleaning, manual start of auto zero
calibration, error code indication, error reset and calibration of lamp
control reference value.
Setting Functions:
<PROGRAM.1> mode: Setting of output range, average coefficient, output value in
failure condition, bi-linear output, high alarm, low alarm and spike
detection function.
<PROGRAM.2> mode: Setting of auto cleaning time and auto zero calibration time, and
selection of enabling/disabling failure detection functions.
