WTR One-Point
Calibration
Check this box if a 1 point calibration can be done. This is typically
used for calibrating thermocouples.
One Point Calibration –
Value Measured ,
Value desired, Cold
junction
Use this to apply the offset correction value to the ADC readings. . e.g.
Temp measured might be 40 C. And user might say the right temp is
45C. Then enter the inputs here to calculate the gain constant
(correction factor) that is used internally for the correction

must be clicked to save the data. For each WFM, 4 consecutive Node IDs must be created all with the
same Device ID. For example if a WFM was configured with the handheld as NodeID = 1, the following
would be set up:

Available Node List
Nodes that can be seen by the BBS but have not been configured.
NodeID
NodeID of the Cypress Envirosystems field device
Device ID
A unique identifier for a WTR device. If the user does not input a
value, the default is the NodeID number.
Name
A basic description of the node.
Unit
Unit of measurement for each Gauge. The user will either specify the
type of measurement such as PSI, H2O, Inch, LBS, or a binary type
(TRUE/FALSE, ON/OFF or ACTIVE/INACTIVE). In case of Binary unit
type the Unit column display is empty in the Readings page. For WTRs
with Device Type = Thermocouples or Thermistors the this field can be
either “C” for Celsius or “F” for Fahrenheit
Node Detail
If a binary value was used in the “Unit” column, the type of binary is
displayed in this column. Additionally, in applications requiring a delta
reading between two existing nodes a virtual delta node can be
configured. Values for the delta nodes are computed based on the
delta logic specified and are updated whenever the existing nodes
change.
