Features an analog bar graph display below the digital digits to show the magnitude of input relative to the full-scale range. Operational Instructions Based on standard RadioShack DMM operating procedures :
To use the 22-805, follow these standard procedures for digital multimeters: Preparation Insert the black probe (common) jack. Insert the jack for voltage and resistance, or the jack for current. Voltage Measurement Rotate the dial to the setting (solid/dashed line for DC, wavy line for AC). If the meter is not auto-ranging, start with the highest range and dial down for better precision. Resistance and Continuity Set the dial to the (ohm) symbol. Ensure the circuit is and capacitors are discharged before testing.
Turn off all power to the circuit and discharge any capacitors before testing. Set the selector dial to the Ω (Ohm) position. radio shack 24 range digital multimeter 22-805 manual
He zipped the yellow case shut. The Radio Shack 22-805 had done its job, bridging the gap between a forgotten basement and a solved mystery, guided by the words on a single, oil-stained piece of paper.

His heart did a small skip. He pulled out a tri-folded, slightly oil-stained booklet. The cover read: Owner’s Manual - 24-Range Digital Multimeter 22-805.
