Note. Recalibrate UUT as necessary throughout this check, using the ADJ. CAL control in conjunction with VOLTS RANGE
(or OPERATE) and CAL switches. Recalibration is necessary if a beyond specified tolerance indication is obtained; Recheck
any erroneous indications after recalibration. Recalibration procedure is given in paragraph 18a (2).
1Begin using .01 NULL switch position.
2Record dc voltage standard indication.
3Difference between the voltage standard indication recorded above and this indication will be between 0.09995 and 0.10005
volt.
b. Adjustments. No adjustments can be made to voltage divider. Recalibration may
correct an out-of-tolerance condition. (See NOTE below table 10.)
23. Final Procedure
a. Deenergize and disconnect all equipment.
b. In accordance with TM 38-750, annotate and affix DA Label 80 (US Army Calibrated
Instrument). When the TI receives limited or special calibration, annotate and affix DA
Label 163 (US Army Limited or Special Calibration). When the TI cannot be adjusted
within tolerance, annotate and affix DA Form 2417 (US Army Calibration System Rejected
Instrument).
SECTION IV
SPECIFIC ITEM IDENTIFICATION
24. Identification. This section identifies specific equipment and accessories as issued
with specific calibration standards sets or specific maintenance equipment groups.
25. Secondary Transfer Calibration Standards Set
a. Equipment Identification. The
equipment listed in
table 11 is
issued with
secondary transfer calibration standards set 6695-00-621-7877 and is to be used in
performing this procedure. When any equipment listed in table 11 is not available,
equivalent items may be substituted provided that they meet the minimum use
specifications listed in table 1 or 6.
