New MATH FSC function to read or write to an .ini file Function name is RIF Function name is WIF Read/Write to .ini Store your cal factors
Read/Write to .ini • Example: • MATH S[1] = “C:\\CALFACTORS.TXT” • MATH M[1] = RIF(S[1], “SECTION 1”, “CF1”) • MATH FSC function to read or write to an .ini file • Where the ini would look like: • [Section 1] • CF1 = 9.97 • CF2 = 1.001 • CF3 = 0.109
Assists debugging problems with IEEE-488 I/O by tracing all MET/CAL data messages written to or read from the IEEE-488 bus Debug data written to file “mcdebug.txt” in <workdir> directory Use command line arguments “-df -trace” IEEE-488 I/O Trace D:\metcal\mcr32.exe -df -trace

Four new FSCs to improve procedure writing and procedure readability: IFcondition ELSE [comment] ELSEIFcondition ENDIF [comment] As with JMPL, condition may be any MATH FSC expression. IF, ELSE, ELSEIF, and ENDIF
IF, ELSE, ELSEIF, and ENDIF # Verify MET/CAL version compatibility. 1.008 IF VERS() < 7.01 1.009 DISP This procedure requires MET/CAL 7.01 or later. 1.010 JMPL END 1.011 ENDIF
IF, ELSE, ELSEIF, and ENDIF 1.001 MEMI Enter an integer: 1.002 IF (MEM == 1) 1.003 DISP value is 1 1.004 ELSEIF (MEM == 2) 1.005 DISP value is 2 1.006 ELSEIF (MEM == 3) 1.007 DISP value is 3 1.008 ELSEIF (MEM > 3) 1.009 DISP value is greater than 3 1.010 ELSE 1.011 DISP value is less than 1 1.012 ENDIF
New FSCs to Allow Looping in Procedures WHILEcondition ENDW [comment] DO [comment] UNTILcondition As with JMPL, condition may be any MATH FSC expression WHILE, ENDW, DO, & UNTIL FSC’s
#This will continue to loop until a valid entry (number <= 3) is # entered 1.001 DO 1.002 MEMI Enter: (1) Insert, (2) Review, (3) Exit 1.003 MATH L[4] = MEM 1.004 UNTIL MEM <= 3 WHILE, ENDW, DO, & UNTIL FSC’s Note: This does NOT allow looping on a reading!!
This procedure fragment will execute the loop 10 times while it counts down the value of MEM. 1.001 MATH MEM = 10 1.002 WHILE (MEM > 0) 1.003 HEAD [MEM][D1000] 1.004 MATH MEM = MEM - 1 1.005 ENDW WHILE, ENDW, DO, & UNTIL FSC’s
Logical AND and Logical OR operators added to MATH Expression Parser Example (Logical AND): IF (M[1] < 10 && M[2] > 5) Example (Logical OR): WHILE (MEM < 5 || MEM1 < 5) 3.011 IF PSUB("744") || (PSUB("2020") && (M[33] >= 2.0)) 3.012 CALL Sub Fluke 744 (1yr) Hart Mode VER RS-232 3.013 ENDIF Logical AND and OR Operators
New “WAIT” FSC Allows procedure writer to invoke a countdown timer with a customized message 2.015 WAIT -t 30 Thermal emfs dissipating... 3.021 WAIT -a –t 18:30 Wait for Self Test.. WAIT FSC
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.” Cal Interval Ranges
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 fromred, green, andyellowevaluation data. 1.001 DISP SET THE UUT TO THE {3 VOLT RANGE} 1.002 ASK+ K 1.003 5520 2.9000V 1% RSLT & Brace Data in Test Results
New MATH FSC function to retrieve database Inventory Table data for a specified asset and a specified field. Function name is INV. Example: MATH S[5] = INV(“A26”, 4202) asset number is “A26” field is 4202 (manufacturer) manufacturer name will be stored in string register S[5] Function: Fetch Inventory Data
New MATH FSC function to retrieve the serial number of a specified asset Function name is SN. Example: MATH MEM2 = SN(“A15”) “A15” is the asset number serial number will be placed in string register MEM2 Function: Get Serial Number
A new MATH FSC function, CTIME, to convert an “HH:MM:SS” time string to an equivalent number of seconds. Example: MEM = CTIME("1:10:15") Function: Time Conversion
A new MATH FSC function, DEG, to convert from radians to degrees. Example: 1.004 MATH MEM = DEG(3.1415926) 1.005 DISP 3.1415926 radians = [MEM] degrees MET/CAL will display: 3.1415926 radians = 179.99999693 degrees Function: Radians to Degrees
New MATH Function: FRND FRND rounds a floating-point number to a specified number of significant digits. Example: MATH MEM = FRND(12.34567, 4) Value of MEM will be 12.35. Floating-Point Rounding Function
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 user’s PATH, but not in the specified MET/CAL user program directory. A typical example would be a program like “WinWord.exe” (Microsoft Word). New “-U” Argument for DOS FSC
New bank of 32 numeric “L” registers for use in the MATH FSC Makes procedure writing easier by providing registers local to each subprocedure invocation Existing MATH functions updated to support L-registers Local Numeric Registers
32 New Local Numeric Registers They Work Like the M[x] Registers 1.001 MATH L[5] = 25 1.002 MATH L[6] = 45 1.003 MATH L[7] = 20 1.004 MATH MEM = AVG_L(5, 7) 1.005 MATH MEM1 = MAX_L(5, 7) 1.006 MATH M[1] = MIN_L(5, 7) 1.007 MATH M[2] = RSS_L(5, 7) 1.008 MATH M[3] = SDEV_L(5, 7) 1.009 DISP The Average is [MEM] 1.009 DISP The Maximum is [MEM1] 1.009 DISP The Minimum is [M1] 1.009 DISP The RSS is [M2] 1.009 DISP The Standard Deviation is [M3]

Guardbanding in MetCal v7.1 • Enable or Disable Guardbanding • Specify the Guardband method • Specify a table of parameter thresholds with associated guardband factors • Choose whether or not to interpolate table values • Supports asymmetrical tolerance specifications
Guardbanding • Specify how indeterminate test results are handled • Call external programs to provide data • Change guardbanding parameters on a per-site, per-workstation, per-procedure, or per-test basis • Report results in a SQL database, for easy access by report generators or other software tools • No modification required for existing procedures
Guard Banding - Results Data • Specification Test Limits • Guardbanding Flag • Guardbanding Method • Guardbanded Test Limits • Guardband Factor • Overall Result for Each Test • Pass • Fail • Indeterminate • Overall Result of Calibration Procedure
