IDENTIFICATION AND DESCRIPTION
This bulletin provides instructions for the
calibration of AC Voltmeter Hewlett-Packard, Model 400EL-02, ME-459/U (Hewlett-
Packard, Model 400EL), and ME-465/U (Hewlett Packard, Model 400E).
The
manufacturers' manuals were used as the prime data sources in compiling these
instructions. The equipment being calibrated will be referred to as the TI (test instrument)
throughout this bulletin.
a. Model Variations. Variations among models are described in text.

prescribed by TB 750-25.
b. Adjustments to be reported are designated (R) at the end of the sentence in which
they appear. When adjustments are in tables, the (R) follows the designated adjustment.
Report only those adjustments made and designated with (R).
