Parameters Explained
To access the programmable parameters see Menu Navigation.
The following is a description of each parameter settings.
Parameter
Description
P02
Par. no. 2 set node address of sensor. If no sensor is found at the current node setting then ‘SEn’
will flash on screen. Press any button to enter P02 node select mode. Use ‘Up’ & ‘Down’ keys
to select between ‘Set’ to manually define node address or ‘SCn’ for automatic node scanning
feature (use ‘Mode’ to enter ‘SEt’ or ‘SCn’ feature). When node is found during scan the sensor
type & node address are toggled. Accept the node address & sensor type found with ‘Mode’ key
or press ‘Up’ or ‘Down’ to continue search
P03
Sets baudrate to be used. Choices are 9,600 or 19,200
P04
Select whether output type is 0-20mA or 4-20mA.
P05
Select whether output is inverted or non-inverted type.
P06
P07
P08
P09
Define 0/4mA and 20mA setpoints. Appendix provides percentages corresponding with specific
engineered units for various sensor. Min scaling between low/high setpoints 2% full range. Excel
worksheet to compute % setpoints available.
P10
Selects ppm or % saturations units to be used as basis for output & main LED display for
connected D.O. sensor.
P11
Selects measured conductivity or else computed PSU, TDS or MΩ units as basis for analogue
output & main LED
P12
P13
Displays cell constant & range mode of EC sensor.
P14
P15
Trim offset for 4mA and Trim span for 20mA
P16
Define sampling rate for connected sensor in seconds
P17
Number of days after which recalibration notification is displayed when sensor is initially
connected to transmitter. If limit is exceeded then ‘CAL’ ‘OLd’ will be dispayed as warning.
P18
Display the sensor type which is connected
P19
Display the formula weight of the measured ion for ISE Sensor. For anion selective sensor value
is shown as flashing
P20
Display type of TDS units which are sent by EC sensor
P21
Resets ALL parameters back to factory set defaults display
