[File Name] is not a valid ASCII file!
You are trying to use an incompatible ASCII file for this conversion.
Make sure you are selecting a NetDAQ ASCII (CSV) file. Other CSV formats
such as Trend Link cannot be used with the NetDAQ conversion utilities (Utilities
menu).
[File Name] is not a valid Binary file!
You are trying to use an incompatible Binary file for this conversion.
Make sure you are selecting a NetDAQ Binary (BIN) file. Other BIN formats
cannot be used with the NetDAQ conversion utilities (Utilities menu).
4W Measurements not allowed on Channels 11-20!
You tried to configure 4-wire measurements on channels 11 to 20. 4-Wire
measurements require two channels spaced a decade apart, e.g., channel 3 and
channel 13. The lower channel is configured and the upper channel is prevented
from being configured. This means you can configure 4-wire measurements only
on channels 1 to 10.
A/D Board Failure! Continue?
Your instrument has detected a fault during internal performance monitoring.
This message does not appear under normal operating conditions. Note the
message and click Yes to continue operations or No to terminate operations. If the
fault recurs, stop operations, and cycle instrument power. If the fault still persists,
remove the instrument from service and return it to a Fluke Service Center for
repair, along with a description of the error message.
A/D Open Thermocouple Detection Failure! Continue?
Your instrument has detected a fault during internal performance monitoring.
This message does not appear under normal operating conditions. Note the
message and click Yes to continue operations or No to terminate operations. If this
fault occurs again, stop operations and cycle instrument power. If the fault still
persists, remove the instrument from service and return it to a Fluke Service
Center for repair, along with a description of the error message.
A/D Overload Detection Failure! Continue?
Your instrument has detected a fault during internal performance monitoring.
This message does not appear under normal operating conditions. Note the
message and click Yes to continue operations or No to terminate operations. If the
fault recurs, stop operations, and cycle instrument power. If the fault still persists,
remove the instrument from service and return it to a Fluke Service Center for
repair, along with a description of the error message.
