Operation
CONFIGURE (continued)
DISCHARGE VAL 1
Number of discarded values after switching from channel 1 to channel 2. Available with the
2-channel version.
LOCATION 2 Settings for location 2
EDIT NAME Enter the name for the measuring location as required. Available with the 2-channel version.
SET PARAMETER Select output: ammonium or ammonium nitrogen. Available with the 2-channel version.
SELECT UNITS Select output: mg/L or ppm. Available with the 2-channel version.
QUANTITY CH 2
Number of measurements in succession ( = measurements on channel 2 +
DISCHARGE VAL 2 channel 2). Available with the 2-channel version.
DISCHARGE VAL 2
Number of discarded values after switching from channel 2 to channel 1. Available with the
2-channel version.
MEASURING
SET INTERVAL
Enter measurement interval (Time interval between two measurements). ATTENTION with
filtration probe and 5 min operation: increased pump speed in the filtration probe, annual
filtration probe maintenance is necessary.
START BY BUS:
START BY BUS:
YES/NO; option whether the instrument is measuring continuously or measurements are
triggered by field-bus. "Fieldbus" must be activated under "TEST/MAINT". Instrument will
switch to 5 min interval when activated.
NUMBER OF MEAS.: Number of measurements after a bus activation.
DISCHARGE:
Number of discharged values that precede the measurements.
AVERAGE: Number of measurements that are averaged. (Affects only the bus triggered measurements)
CLEANING
SET INTERVAL Number of hours between the cleanings
START
Start time for the cleaning (In case of more than one cleaning per day: Enter start time for the
first cleaning.)
DISCHARGE Number of measured values that are discarded after a cleaning operation.
SET OUTMODE
Value that is output during a cleaning operation and the following discarded values.
HOLD = last measured value, SET TRANSFER = value to be entered.
CUVETTE TEMP.
Temperature for cuvette and electrode
Recommended: Select 45 °C at air temperature: up to 35 °C, 50 °C at air temperature: up to
40 °C, 55 °C at air temperature: up to 45 °C, at 55 °C reduced accuracy and shortened
electrode service life may occur.
TUBE HEATING
ON
Probe tube heating switches on at the start of the selected month when using the Filter
Probe sc.
OFF
Probe tube heating switches off at the end of the selected month when using the Filter
Probe sc.
REAG. WARNING
REAG. WARNING
On/Off
When On is selected: determines the warning output if the reagent levels are low
WARNING Determines the level below which the reagent must drop to trigger the warning.
STAT. MODUL.WAR.
40 %, 30 %, 15 %
Warning is released: when a filter probe is installed and the status of filtration modules fall
below level
STATUS MODUL.ERR
14 %,10 %,8 %, OFF
An error is generated: when a filter probe is installed and the status of filtration modules fall
below level. When switched to OFF, a deactivated sample detection will be switched to
"warning".
