HELP
– You can press F1 for Help
on a selected or highlighted field
or control. You can also click the
[?] button in the upper-right hand
corner of the screen and click to
point to a field or control to get a
Help message pertaining to the
item you pointed to.
If more than one transmitter is connected via USB through a USB hub, the software
automatically opens a connection with one of the transmitters and “Read
Complete” is indicated in the message bar at the bottom of the screen. You can
discern which transmitter is open by referring to the product’s unique serial number
indicated next to the Product Name. If your intent was to open a different hub
transmitter, you will have to “Close” the current connection and use the Device
Name scroll bar to select another unit (discern unit by serial number). Then click
“Open” to communicate with it. If you break the USB connection to a transmitter,
the software will automatically close the connection for you. When you reconnect
the cable, you will have to click “Open” to reopen communication with the
transmitter.
Open the Transmitter for Communication….
Once you have opened a transmitter for communication, the device status will
change from “Ready” to “Connected”, and the transmitter ID information will be
displayed in the Product Name, Manufacturer, and Serial Number fields. At this
point, the connected transmitter is ready for configuration and the appropriate
configuration fields become active and await your input.
If you want to see how the connected unit is already configured before changing its
configuration, click the “Get Config” button of the Configuration & Calibration
controls to retrieve its current configuration information. Note the message bar at
the bottom of the screen and it should display a message like “Read Complete!
Normal Operation, inputs in range”
IMPORTANT:
If you make any changes to the Configuration Parameters, you will
have to recalibrate the unit via the “Start Calibration” button in order to actually
write those changes to the transmitter.
Select the Input Type…
In the Calibration section of this screen, select an input type: Platinum RTD, or
Resistance.
If you select
“Platinum RTD”,
your output will be linear with respect to sensor
temperature, not resistance, and you will additionally have to use the “Alpha
Value” scroll window to select your particular RTD curve type (alpha is only
used by the software to recommend resistance values during calibration).
If you select
“Resistance”,
your output current will be linear with respect to
sensor resistance, not temperature, and no special linearization will be
performed.
Note that you must already have loop power connected to the transmitter
before you execute this software. If you do not, the software will prompt you
to make this connection when you execute the software program. If you later
interrupt loop power while already using the software and while connected to
USB, you may have to re-open communication with the unit.
