Ultimate Guide to the Micronta 22-212 Multimeter: Manual, Specs, and Usage
Gently pry off the back cover to expose the battery compartment and internal circuitry.
Connect the probes across the component (ensure the circuit power is completely off).
This is the topmost scale. It reads from right to left (infinity on the far left, zero on the far right).
If your readings seem off or it isn't working at all, try these checks: micronta multimeter 22 212 user manual
Touch probes to the circuit in parallel. Read the value on the black DC or red AC scale as appropriate. Current must be measured in series with the circuit.
Touch the test probes to the voltage source. Polarity does not matter for AC measurements. Read the value on the corresponding AC scale. 4. Measuring Resistance (Ohms) The internal battery powers this function.
Turn the rotary switch to the range for wall outlets, or a lower range for small transformers.
Reassemble the case tightly, taking care not to pinch the internal wiring. Ultimate Guide to the Micronta 22-212 Multimeter: Manual,

Before any measurement, look at the meter face. Locate the small screw (usually plastic) directly below the center of the needle pivot. Use a small flathead screwdriver to turn it until the needle rests exactly on the mark at the far left of the scale (for voltage/current) — not the infinity symbol .
Read the linear scale. If the reading is very low, turn off the power, switch down to the or 0.5 mA range, reapply power, and read the corresponding scale adjustments. Maintenance and Care It reads from right to left (infinity on
Up to 100k ohms (with a center scale of 3.6k ohms).
remains a trusted tool for technicians, hobbyists, and vintage electronics collectors due to its sensitivity and reliability. Its 3-color mirrored scale allows for quick, accurate readings of DC/AC voltage, DC current, and resistance. 1. Safety and Initial Setup Before using the Micronta 22-212
Insert the test leads into their respective jacks ( and + ). Set the rotary switch to the desired AC V range.
