Micronta Multimeter 22-212 User Manual: A Comprehensive Guide
Core Specifications
is a vintage analog multitester originally sold through Radio Shack . Known for its compact "pocket" size, it is a manual-ranging tool designed for basic electrical testing including voltage, current, and resistance.
Using the Manual: A Quick Example
- Green/Black Arc (0-10): DC Voltage and Current (linear).
- Red Arc (0-2.5): 2.5V AC range (linear but offset).
- Green Log Arc (Ω): Resistance (non-linear, infinite at left, zero at right).
- Decibel Scale (dB): Bottom scale for audio level measurements.
- DC Voltage (DCV): Measures direct current voltage in five ranges: 0.25V, 2.5V, 10V, 50V, 250V, 500V, and 1000V.
- AC Voltage (ACV): Measures alternating current voltage in ranges: 10V, 50V, 250V, 500V, and 1000V.
- DC Current (DCA): Measures direct current amperage in ranges: 50µA, 2.5mA, 25mA, and 250mA.
- Resistance (Ohms): Measures resistance in three multiplier ranges (x1, x10, x1K), requiring an internal battery.
- Decibels (dB): Includes a dB scale for audio measurements, generally read using the AC voltage ranges.
Zero the Scale:
Touch the red and black probe tips together. The needle should sweep to "0" on the top green scale. If it doesn't, turn the OHMS ADJ knob until it does. micronta multimeter 22 212 user manual
