Current must be measured in with the circuit. You must break the circuit and insert the meter into the gap. Insert the black lead into COM .
Plug the black test lead into the (Common) jack and the red lead into the V/Ω/mA jack.
The manual highlighted features that were innovative for the consumer market at the time:
Elias wasn't just a fixer; he was a scavenger. He looked at the carrying case again. There was a false bottom in the foam. He dug his fingers into the padding, tearing away the brittle foam, until he felt the crinkle of paper. radio shack 24 range digital multimeter 22-805 manual
Like any fine instrument, proper care will ensure its longevity and accuracy:
To measure current up to 20A, the red lead must be moved to the specific high-current (20A) jack .
The LCD flickered to life, the backlight a ghostly green in the dim basement. Current must be measured in with the circuit
The 22-805 uses two fuses for overcurrent protection: an 800mA/250V 5x20mm fuse for the low-current mA ranges, and a 20A/250V 6x30mm (super fast-blow) fuse for the high-current 20A range. Always replace a blown fuse with one of the exact same type and rating.
Finding a PDF of the online today is like finding a lost episode of The Electronics Hour . The language inside is pure 1995: "Never use the meter if the case is cracked (have a qualified technician service it)." It assumes a world where you actually know a qualified technician.
