Model BDM40
Benchtop Digital Multimeter |
| |
|
This 4 1/2 digit (20,000 counts) digital
multimeter features True RMS (AC or AC + DC coupling) measurement
capabilities to assure accuracy regardless of the types of
waveforms. The BDM40-UA features high resolution at a low cost,
which makes it ideal for production test, QA test, depot service and
university and school labs.
Measurement capabilities include voltage from 10
mV to 1200 V DC and to 1000 V AC, current from 10 mA to
20 A, and resistance from 10 mΩ to 20 MΩ.
Diode test is provided on the 2 kW range. The interlocking push
buttons on the front panel provide easy selection of functions and
ranges. Bold labels on the input jacks increase visibility and offer
an added safety, as does the fully fused 2A jack.
The BDM40-UA's full 360° adjustable tilt bail and
LED display maximize readability for most any bench application.
Each meter comes with standard test leads, power cord, and users
manual. A full line of optional probes, current clamps and test
leads is available to meet your application needs.
