Always store the multimeter with the selector switch set to the OFF position (or the highest AC V range if an explicit off switch isn't present) to prevent battery drain or meter movement strain during transit.
Set the rotary switch to the highest DC V range (1000V) if the voltage is unknown. If you know the voltage is low, select the closest range higher than the expected voltage (options typically include 10V, 50V, 250V, 1000V).
Turn the multimeter over and remove the screw holding the rear case together.
The maximum capacity for this model is 150mA DC. Exceeding this can blow the internal glass fuse. MICRONTA 22-212 MULTIMETER - All About Circuits Forum
To measure resistance, short the test probes together and turn the OHMS ADJ knob (typically red) until the needle points to "0" on the green top scale. This must be done every time you change resistance ranges. Voltage Measurements: micronta multimeter 22 212 user manual
The Micronta 22-212 solves this with a built-in mirror strip. When reading the meter, shift your head until the actual metal needle perfectly aligns with and hides its own reflection in the mirror. Once the reflection disappears behind the physical needle, look directly up or down to read the exact graduation mark. Maintenance and Battery Replacement
Plug the black test lead into the -COM jack and the red test lead into the + V-Ω-A jack. 2. Measuring Resistance (Ohms)

Where to get the manual
The manual would emphasize starting with the (e.g., 1000V) and working your way down to prevent the needle from slamming into the side of the case and damaging the delicate movement.
Example on the 1000V range: Read the 0–10 scale and multiply the final reading by 100. 3. Measuring AC Voltage (AC V) Turn the multimeter over and remove the screw
Touch the probes across the circuit or component in parallel.
Before measuring, familiarize yourself with the tester's front panel. Understanding each component is your first step toward accurate and safe use.
