Error and Status Messages

Invalid Channel Number!

Your equation contains a channel number that is not expressed with the correct syntax.

When used within an equation, channel numbers must be preceded by the letter ‘c’ (or ‘C’). The channel number itself is expressed as an integer between 1 and 30. For example, channel 21 should be expressed as c21 (or C21).

Invalid Equation!

NetDAQ Logger attempted to read an equation that is missing or was entered in invalid syntax.

This messages appears when a computed function is defined as Equation, but the equation is either missing from the dialog box or was entered in a format that cannot be read by NetDAQ Logger. Verify the equation has been entered, check for missing operators or operands, misspelled operators, or illegal characters, and correct the equation as necessary.

Invalid Factor (M) Value!

You have entered a Factor (M) value for Mx+B scaling that is excessively large.

Select a M value that is less than +9.9999E+9.

Invalid IP Address or Socket Port Number! Reconfigure Communications!

Your Communications Configuration File does not have a valid IP Address, or Socket Port for this instrument. (General Network only.)

Make sure you have not set an IP address to 000.000.000.000 in the Communications Configuration File. (Select the Communications Config command from the Setup menu.)

Invalid Maximum Value for Scaled Range!

You have entered an invalid Maximum Value for the Mx+B Input Range calculation.

Enter a Maximum Value that is less than +9.9999E+9.

Invalid Maximum Value for Input Range!

You have entered an invalid Maximum Value for the Mx+B Input Range calculation.

Enter a Maximum Value that is less than +9.9999E+9.
