1. What is the calibration process
for a Digital Multimeter?

2. An Introduction
A digital multimeter (DMM) is one of the most used tools for test and
measurement. Quality measurements and processes rely on the
frequent operation of a digital multimeter. However, certain factors
like environment, time, and physical use (or abuses) can change a
digital multimeter’s characteristics. That’s why it becomes necessary to
calibrate or authenticate the performance of a digital multimeter
regularly.

3. Requirements of Digital
Multimeter
Usually, the DMM calibration time interval is yearly basis. But some
requirements may have a different calibration interval or period in the
middle of calibrations. The time in the middle of calibrations can also
be changed as it depends on time, environment, and use.

4. Functions of Digital Multimeter
One can calibrate each device function under test (DUT) using a multi-
product calibrator. If you use a Fluke Calibration multi-product
calibrator, the front panel has a simplistic and easy display, especially
for first-time operators. For calibration, we can use a 5522A Multi-
Product Calibrator, a Fluke 87V Digital Multimeter, and a pair of
compatible test leads.

5. Important Calibration Steps
• Calibrating direct voltage,
• Calibrating alternating voltage,
• Calibrating resistance,
• Calibrating capacitance,
• Calibrating direct current

6. Operations Performed on Digital
Multimeter
Given below information is considered mandatory to provide a
complete comprehension of the operations performed on the digital
multimeter:
• identification of the calibration method used
• evidence that the measurements are traceable
• the conditions such as temperature and humidity) that influence
the calibration results
• the calibration results with measurement units
