24
Cal Interval Ranges

• Many users extend the cal intervals for their
  references.
• MET/CAL accuracy files will now allow a range of
  cal intervals to be mapped to a particular
  specification.
• For example Use the 90-day specs for any cal
  interval from 2 months to 6 months.

25
RSLT Brace Data in Test Results

• The Test Results window now includes data
  generated by RSLT statements, and brace data
  (xxx) from message-type FSCs.
• Strings are shown in cyan (cyan) to distinguish
  from red, green, and yellow evaluation data.
• 1.001 DISP SET THE UUT TO THE 3 VOLT
  RANGE

  Inventory Table data for a specified asset and a
  specified field.
• Function name is INV.
• Example MATH S5 INV(A26, 4202)
• asset number is A26

• manufacturer name will be stored in string
  register S5

27
Function Get Serial Number

  specified number of significant digits.
• Example
• MATH MEM FRND(12.34567, 4)
• Value of MEM will be 12.35.

31
New -U Argument for DOS FSC

• A new argument, -u has been added for use with
  the DOS and DOSE FSCs.
• -u overrides the user of the user_prog_dir
  initialization file parameter.
• This allows MET/CAL to find programs
  (executables) which are in the users PATH, but
  not in the specified MET/CAL user program
  directory.
• A typical example would be a program like
  WinWord.exe (Microsoft Word).

32
Local Numeric Registers
