receive prompt the upload command will timeout and will have to be issued again.
To copy this configuration back into a unit or transfer it to another MFT B-Series with the
same configuration file format, use the command:
<Esc>download<Ret>,
where, <Esc> is the escape key on your keyboard followed by the text “download” and
<Ret> is the enter or return key. A prompt will be displayed to indicate that the Xmodem
transmit is ready to start on the PC. Again you have 30 seconds before it times out.
Using HyperTerminal select Transfer, Send File and select the binary configuration file to
be transferred to the MFT B-Series Unit.
The above commands are effective only when the MFT B-Series is in
Run Mode
. It is
recommended to turn OFF the terminal echo during this process to avoid dumping
character strings on the terminal screen. Refer to the section
Overview of the user
Interface
on how to turn the terminal echo ON and OFF.
Calibration of the Analog Output
A menu is available to perform the calibration of the analog output(s) on MFT series flow
meters. You enter the Analog Output Calibration menu and use an external meter to
“dial in” the 4.0 mA Zero and then the 20.0 mA Span. The
^
v
keys are used to raise or
lower the output until it matches the two conditions listed. Once they are in agreement,
the
E
key is pressed to accept this value. See the Configuration section of the manual
for step-by-step instructions.
Calibration of the Analog Input
There are no on board menus for the user to calibrate the analog inputs. This is a
Factory process only. If your transmitter is reading the ambient temperature within a few
degrees when the flow rate is higher than 100 SFPM (0.5 SMPS), then the input is
properly calibrated and your sensor is most likely working also. You can also test the
independent calibrator under the zero-span menu to confirm the accuracy of the
calibration
Status Alarms and NE-43Alarms
The MFT B-Series has two types of alarm mechanisms - status alarms and a NE-43
alarm. The MFT B-Series meters can be factory configured with up to two (2) status
