13.4.2 Character Processing

The data entered into the calibrator is processed as follows:

• ASCII characters are discarded if their decimal equivalent is less than 32 (space),

except 10 (LF) and 13 (CR):

• Data is taken as 7-bit ASCII

• The most significant data bit is ignored.

• Upper or lower case is acceptable.

13.4.3 Response Data Types

The data returned by the calibrator can be divided into four types:

Integer

For most computers and controllers they are decimal numbers ranging from -32768 to
32768. For example:

FAULT? could return 110

Floating

Floating numbers have up to 15 significant figures and exponents. For example:
