SECTION I
IDENTIFICATION AND DESCRIPTION

1. Test Instrument Identification. This bulletin provides instructions for the
calibration of Digital Multimeter, Tektronix, Types DM 501 and DM 501A with DC High
Voltage Probe, Ballantine, Model 10800C; John Fluke, Model 80K-40; and Tektronix, Type
010-0277-00. The manufacturer's 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. The John Fluke, Model 80K-40 is the same as the Tektronix,
Type 010-0277-00 probe and is nonadjustable.

b. Time and Technique. The time required for this calibration is approximately 1.5
hours, using the dc and low frequency technique.

2. Forms, Records, and Reports

a. Forms, records, and reports required for calibration personnel at all levels are
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).
