New instruction manual: MI 3309 BT DeltaGT


Due to several recent changes to safety standards for electrical equipment testing, we have updated instruction manuals for some of our testers, including the MI 3309 BT DeltaGT. The updated instruction manual now contains information about the new EN standards: EN 50699 (VDE 0702) Recurrent Test of Electrical Equipment and EN 50678 (VDE 0701) General procedure for verifying the effectiveness of the protective measures of electrical equipment after repair.
More information about the new standards and how they are supported by Metrel testers is available in a comprehensive table available by clicking the button “New standards and Metrel testers”.

In addition to an updated instruction manual, we have just recently also published new firmware (version 1.271) for the MI 3309 BT DeltaGT. You can view the release notes or download the firmware by clicking the “Firmware (1.271) release notes” or “Download new firmware (1.271)” button below.
