Digital multimeters tests
Fluke 8000A - ac measurement
Fluke 8000A Fluke 8000A

Fluke 8000A is desk-top 3½-digits low cost multimeter with power supply. It has been purchased in 1975 and never calibrated. Accordings the operational manual, the errors of ac ranges should be ±0.5% from readable value (45 Hz až 10 kHz) and 1% at frequences 10 kHz to 20 kHz. Input impedance should be 10 MΩ.

Fluke 8000A - tests results Fig. 1 - test results

Results of true RMS values in milivolts of sinus signal from APN-62 Rohde Schwarz generator at various frequences.

Values with blue background are for range 2 Volts. Values with yellow background are for range 20 Volts.

Date of tests: 16.July 2009

Fluke 8000A - measured errors Fig. 2 - measured errors

The graph shows errors of measured values dependings frequence at range 2 Volts. The tested instrument is usable from 20 Hz up to 20 kHz for signals above 20 mV. For signals from 10 mV to 20 mV is the instrument usable from 100 Hz.

Fluke 8000A - measured errors Fig. 3 - measured errors, detail view

This graph shows errors of measured values dependings frequence at range 20 Volts. With increased sgnal amplitude increased error and the instrument is usable in frequency range from 50 Hz to 500 Hz.
