This page is used to generate calibration files for the Siglent SDM3045X, SDM3055, SDM3065X multimeters.
As of firmware version 3.01.01.12R1 (SDM3065X), 1.01.01.27R2 (SDM3055), 5.01.01.09R2 (SDM3045X) you can now do on screen calibrations directly on the multimeter. You can still use the original method if you are still using the older firmware, but I recommend that you update your firmware !
Siglent listened to my suggestion of a better way of doing the calibrations (as I describe in one of the original videos) and actually implemented it, well done Siglent!
Below is an updated video showing the new calibration process:
I have added a tracker for the calibration files to log if they are working properly or not for each SDM model. If a file doesn't work the SDM fails to use the file and no harm is done so it is safe to try !)
Follow these instructions BEFORE you start to enter any calibration data
VERY IMPORTANT: make sure the meter is set to the Factory calibration data and not using a previous User calibration (Utility/System Setup/Calibration), otherwise the calibration corrections will not be correct!
Make sure that Relative Mode is turned off for each mode that is calibrated.
The default values are for the SDM3065X, make sure you select the correct SDM model BEFORE doing anything so that the values can be setup for you.
Consider entering your units serial number so that it can be included in the CSV file name, and allows you to retrieve your last calibration data.
Make sure that the SDM has been able to warm up for at least 2 hours, and ideally longer than 4 hours before trying to perform the calibration.
The calibrator or references used SHOULD have an accuracy an order of magnitude more than the SDM, however, an accurate and trusted reference that equals the resolution of the SDM can be used with reduced accuracy.
I made two videos demonstrating the process for the DCV modes using the original Siglent calibration data files, this site allows you to generate the correct files without a lot of the complications associated with the original process. I highly recommend that you watch both videos before beginning this process so that you have an understanding of what is required.
