Results test tolerance (tol) field prerequisites

Looking for the procedure requirements so the results test tolerance (tol) field will be calculated.  Could not find anything specific in documentation.  Running MetCal 7.3.  We have several manual entry procedures that do not use standards FSC's that are not calculating the field and as such are not calculating the tur field.  They have full uncertainties and all of those results are entered fine.  Just the tol and tur field with no entry.

Do you have an entry in your TOL field of the MEMC or MEMCX FSC?

The TUR is calculated using an ACC field (If using FSCs, this is provided in the metcal/acc folder). If you're not using FSCs, you have to provide it. ACC is the accuracy of the standard. (1.001 ACC 25.000V 0.01%).

You also need a TOL field (The accuracy of the UUT). Can either be in a TOL line or in the MEMC or MEMCX line.

Using MEMC(X) lines with TOL.  The Nominal comes from a memory register and tolerances come from a TOL FSC.  No ACC line.  So you are saying he results.tol filed requires an ACC or standards FSC in procedure test section?  The literature is a bit vague.  The Results Table document for V7.00 says the results.tol is the linearized test tolerance.  Since I have test tolerances and they are saved in the results fields was not sure why the tol field would not calculate?

Below is an example. When not using an FSC, you must provide the ACC (Standard Accuracy). The TOL (UUT Accuracy) is in the MEMCX line. Hope this doesn't get jumbled. If so, see attached txt file.

  3.002  RSLT         =
  3.003  HEAD         INSULATION RESISTANCE ACCURACY TESTS:{ 2000 MOhm Range}
  3.004  TARGET       -p
  3.005  DISP         Set the decade resistor to 1900 Mohms.
  3.005  DISP         Turn the UUT rotary switch to 1000 V.
  3.006  TARGET       -m
  3.007  MEMI         Press the UUT TEST key.
  3.007  MEMI
  3.007  MEMI         Release the TEST key when the reading settles.
  3.007  MEMI
  3.007  MEMI         Enter UUT reading in megohms:
  3.008  ACC          1900MZ         0.5%
  3.009  MEMCX  2000  1900MZ         38U           1000V
