As with any type of tooling or equipment, a Fluke Multimeter will eventually need to be calibrated. Whether you’re using it for a hobby or are in a highly regulated industry, in order to get consistent, accurate readings from the Fluke you need to calibrate regularly. The timing for calibration is often dependent on your environment; whether it is in cold or harsh weather, whether it has been dropped, how often you are using it, etc. In this blog post, we’re going to explain how to check your fluke multimeter to see if it is in need of calibration.
These steps are compatible with a Fluke 80 Series V Multimeter. Any older versions will need to be adjusted from the potentiometers inside the equipment in order to bring them up to manufacturer specifications.
WARNING: You will be working with electric currents and run the risk of shock or damage to the meter if performed incorrectly. Please check your Fluke Calibration Manual before performing a Fluke calibration or refer to a specialized calibration technician.
Hold the Min/Max button down while turning the rotary know to the “VAC” position. Once you see the word “CAL” display on the screen, you can release the Min/Max button. You are now operating in calibration mode
Press the Auto/Hold button again. A line of question marks will appear and you will enter your password. To complete, press the Auto/Hold button again.
When “C-01” displays on the screen, attach the outputs from the meter to the inputs on your electric calibrator. According to the Fluke meter guide, turn the dial on the calibrator to the position corresponding to “C-01”. To complete, press with Auto/Hold button again.
When “C-02” displays, again find the correct position according to the guide to turn the calibrator dial to. To complete, press Auto/Hold again.
Repeat this until you have completed the process up to “C-31”
When the process has been completed, “END” will display on the screen and you can press Auto/Hold again to complete the calibration
