TB 9-6625-2246-50
IDENTIFICATION AND DESCRIPTION
calibration of Multimeter, Hewlett-Packard Model 3458A. The manufacturer's manual
was used as the prime data source in compiling these instructions. The equipment being
calibrated will be referred to as the TI (test instrument) throughout this bulletin.
a. Model Variations. None.
hours, using the dc and low frequency technique
prescribed by TB 750-25.
b. All software adjustments made in Section IV are reportable. Report software
adjustments made using parameter and range failing performance check; i.e., 10 V dc,
100Ω, etc.
pertain to this calibration are listed in table 1.
