Radio Shack 24 Range Digital Multimeter 22-805 Manual Jun 2026
Before diving in, it's helpful to note that the RadioShack 22-805 is functionally identical to meters like the Metex ME-11 and Voltcraft ME-11 —an OEM (Original Equipment Manufacturer) product. This means manuals, software, and technical tips for those models are often directly applicable.
If you own (or have just inherited) a 22-805, you’ve likely faced one critical problem: A multimeter without a manual is like a car without a steering wheel—you can turn it on, but you won't know where you're going.
If the meter cannot measure current, the fuse is likely blown. Open the case as described above.

"Step one," he whispered to the silence of the basement.
Current measurements must be taken in series, meaning the meter must become part of the wire loop. Never place the leads across a voltage source while in current mode, or you will blow the internal fuse or damage the device.
Before measuring, familiarize yourself with the physical layout. Looking at the front panel, you have:
: Digital numeric display paired with a rapid Analog Bargraph to track fast-moving signal trends. Understanding the Front Panel Layout and Controls
: Never attempt to measure DC voltages above 1,000V or AC above 750V RMS to avoid shock or equipment damage. Battery Care
