After clicking “OK”, the software closes the connection and the screen
returns back to its initial state, prior to connecting a module to USB. When
you reconnect the USB cable, you will have to click “Open” to reopen
communication with the transmitter. If you have more than one transmitter
connected via a hub, then you will have to use the Device Name scroll bar
to first select a transmitter (discern unit by serial number), and then click
“Open” to open communication with it.
Note that if you intend to Test or Calibrate any elements of this transmitter,
you should already have loop power connected to the transmitter before you
execute this software.
At this point, the connected transmitter is ready for reconfiguration 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 from Unit” button of the
Configuration controls section to retrieve its current configuration
information. Note the message bar at the bottom of the screen and it should
display a
message like “No error encountered while reading configuration”
Select the Input Type (T/C Type or ±100mVDC)
…
In the Configuration section of this screen, select an input type: T/C Type J,
K, T, R, S, E, B, N, or 100mV.
•
If you select any T/C type, your output will be linear with respect to
sensor temperature, not sensor millivolts.
•
If you select
“100mV”, your output current will be linear with respect to
input voltage, not temperature, and no special linearization will be
performed. Note that “100mV” represents ±100mV range capability.
Select Upscale or Downscale
Lead Break Detection…
Upon sensor burnout or a broken sensor lead, you can select
“Downscale
”
to send the output current to its down-scale limit (~3.5mA), or
“Upscale”
to
send the output current to the over-scale limit (~24mA). You can usually
discern, a lead break or open sensor from an over-range or under-range
input signal by noting its current level. Note that outputs can be reverse
acting, and upscale for a reverse acting output will remain ~24mA.
Likewise, downscale for a reverse acting output still corresponds to a
current level ~3.5mA.
Select a Filter Control Level (None, Low, Medium, or High)
…
Note that in addition to the analog filters of this unit, it also has the capability
of applying digital filtering. Increased filtering is useful to help minimize the
negative effects of noisy input signals but will increase the response time of
the unit accordingly. You can select the amount of filtering as None, Low,
Medium, or High. Note the approximate response times indicated next to
each filter level.
