Radio Shack 24 Range Digital Multimeter 22-805 Manual 【720p × FHD】
Let’s decode the name. "24 Range" doesn't mean it measures 24 different things. It means that via the giant, satisfyingly chunky rotary dial, you have 24 distinct positions. You get the usual suspects: DCV (from 200mV to 1000V), ACV (200V to 750V), Resistance (200Ω to 2000kΩ), and DC Current (200µA to 10A). But here’s where the 22-805 gets quirky: It includes a dedicated Diode Test and Transistor hFE Test (via a weird little six-socket port on the front).
Most users lost the manual because they assumed it was obvious. It’s not.
"Never apply more than 1000V DC or 750V AC between any input jack and earth ground. Do not measure voltage while the test leads are plugged into the 10A or ACA jacks."
Before measuring, familiarize yourself with the physical layout. Looking at the front panel, you have:
The RadioShack 22-805 is a basic, non-CAT rated meter. Do not use it on high-energy circuits (main breaker panels, industrial equipment, 480V systems). It’s excellent for:
For modern house wiring or complex troubleshooting, invest in a modern multimeter with a CAT III safety rating.
The Radio Shack 24 Range Digital Multimeter 22-805 is a classic piece of test equipment that remains perfectly serviceable nearly three decades after its release. The key to using it safely and accurately is having the original manual—or a reliable substitute like this guide.
Whether you repair vintage radios, troubleshoot car electrical systems, or just check household batteries, the 22-805 will serve you well as long as you respect its ranges, replace its fuses, and download the official manual for complex operations.
