U.S. Army Limited or Special Calibration Label

TB 750-25

C-5. U.S. Army Limited or Special Calibration Label (DA Label 163, Figure C-2)

NOTE

Figure C-2 is depicted larger than the actual DA Label 163.

a. Uses:

(1) Verifies that the instrument received a limited calibration, in that certain

parameters or ranges (identified on the label) required repair and could not be

calibrated, or certain parameters and/or ranges were not calibrated, or certain

parameters and/or ranges were calibrated to less stringent tolerances than those

specified in the approved calibration procedures.

(2) Verifies that the instrument received a special calibration in that certain

parameters or ranges (identified on the label) were calibrated to more stringent

tolerances than those specified in the approved calibration procedure and the label

serving as a calibration report. Written request is required from owner of the item.

(3) Indicates that with normal care in handling and use during the calibration

interval (indicated by the date calibrated and the date calibration is void) the special

calibration of the instrument will have an acceptable probability of remaining within the

special calibration tolerances.

b. Preparation. The individual who accomplishes the limited or special calibration

of an instrument will complete DA Label 163. Entries in blocks 1 through 6 will be the

same as outlined in paragraph C-4b above for DA Label 80. Entries in blocks 7 and 8 will

be as follows:

(1) DA Label 163 for limited calibration (fig. C-2).

(a) Block 7 - Line out (obliterate) the words "Special Calibration." Do not line

out (obliterate) the words "Limited Calibration - Do Not Use."

(b) Block 7a - Parameter/value. Enter the parameters, ranges or values that

were not calibrated, are inoperative, or are out of tolerance. Ranges or values not listed

on DA Label 163 must be calibrated to tolerances specified in the approved calibration

procedures.

not been calibrated, enter "NOT CALIBR." For parameters, ranges, or values that are

out of tolerance, enter out-of-tolerance values or percentage of accuracy's. For

parameters, ranges, or values that are not operative, enter "INOPERATIVE."
