The meter is limited to 150mA . Ensure your circuit does not exceed this before testing.
Connect the probes to the circuit. If the reading is low, move the dial down to a lower range for better precision. Caution: Never exceed the 1000V AC/DC maximum input. 3. Measuring DC Current
The Micronta 22-212 is a vintage 8-range analog multitester originally sold through Radio Shack. Known for its durable handheld design and simplicity, it remains a popular tool for hobbyists and collectors who prefer analog needle movements for tracking fluctuating signals. micronta multimeter 22 212 user manual
3-color mirrored analog scale to prevent parallax error. Operating Instructions 1. Preparation and Battery Installation
Up to 100k ohms (center scale 3.6k ohms). Safety Category: CAT II. The meter is limited to 150mA
Remove the battery if the meter will be unused for more than a week to prevent corrosion from leaks.
If you cannot zero the "0 OHMS" scale, the internal AA battery is likely weak and needs replacement. If the reading is low, move the dial
If the DC current or resistance ranges fail to respond, check the internal glass fuse.
Set the range to OHMS, touch the probe tips together, and turn the OHM ADJ knob until the needle points to "0" on the top green scale. 2. Measuring Voltage (AC/DC)
