The manual contains no calibration instructions, no internal schematic, no parts list. For a technician wanting to repair the meter itself, the manual is useless. This is fine for a $20 meter, but a notable limitation.
Turn off all power to the circuit being tested. Disconnect at least one leg of the component (like a resistor) to prevent back-circuits. Insert the leads into (-) and (+). Set the switch to .
The Micronta 22-212 is a vintage, pocket-sized analog multimeter sold by RadioShack during the late 20th century. Known for its compact design, fold-out stand, and mirrored scale, this classic test instrument remains highly useful for hobbyists, electronics enthusiasts, and DIYers. This comprehensive guide serves as an expanded manual to help you safely operate, read, and maintain your Micronta 22-212 multimeter. Technical Specifications and Features
The manual’s core strength is its procedural clarity. For a device with only one function (measuring AC voltage, typically 0-150V and 0-600V scales), the instructions are refreshingly direct.
Is the needle entirely?
is often unfused, so use extreme caution to avoid damaging the internal circuitry. Reading the Analog Scales The face of the can be a bit busy. Follow these color codes: Green (Top) : Resistance/Ohms (reads right-to-left). : DC Voltage and Current. : AC Voltage. Pro Maintenance Tips
The top arc displays resistance (Ohms), reading from right (zero) to left (infinity). Below the Ohm scale are the linear scales for AC and DC voltage and current, which read from left (zero) to right. Range Selector Switch

Connect the black probe to the negative side of the circuit and the red probe to the positive side. The manual contains no calibration instructions, no internal
Located directly below the meter face. Turn this gently with a small flathead screwdriver to align the needle perfectly with the left-side zero mark when the meter is off.
Because the Micronta 22-212 is an older model, it can act up.
ADJ): Used to calibrate the meter for resistance testing. Short the test leads together and turn this knob until the needle points exactly to "0" on the top Ohms scale.
