Micronta LCD Auto Range Digital Multimeter
This is another unit of mine that has hardly been used. Used it a few times but its been laying in a drawer for a long time. I'll bet I didn't use this unit more then 3 or 4 times. As with all my equipment its never been abused, well taken care of and comes with instructions.
Latestst IC and Display Technology - ensures reliability, accracy, stability, and east of operation.
Full Auto-Ranging with Manual-Ranging Override - makes it easier and safer to use your meter.
Bar-Graph Display - makes it easier to quickly identify nulls, peaks, and trends.
Data Hold Function - freezes the display so that you can keep the reading on the display even after you disconnect the probes.
Overload and Transit Protection - helps protect the meter from overvoltage on most ranges.
Continuity Buzzer Function - lets you quickly check for continuity.
Diode Check Function - lets you safely check semiconductors for open, shorted or normal junctions.
Full Auto-Polarity Operation - Protects your meter and gives valid measurments when you connect the leads in reverse polarity.
Low-Battery Indicator - shows you when you need to replace the battries.
Fold-Out Stand - lets you adjust the position of the meter for best visibility on a flat surface, and lets you hag the meter.

Diode Check Function: For checking open, shorted, or normal semiconductors.
Continuity Function: Continuity buzzer sounds at less then 295 ohms (+ - 20 ohms) input resistance. When input is shorted, buzzer sounds for about 150 msec.
Input Impedance: 10 Megohm (DCV/ACV) More then 100 Megohm on 300 mV DC range
Range Control: Full auto-range or manual-range control, selectable by RANGE SELECT switch.
Bar Graph: 31-dot display (including zero) A/D 6 bit accuracy: + - 4 LSB
Power Source: Four AA 1.5V battries.
Power Consumption: 10 mW typical.
Low-Battery Indication: BATT on the left of the display indicates when power supply is below 2.5V (approx.)
Overrange Indication: 3000 with blibking "3". When measured value exceeds the maximum value, all digits on display blink.
Operating Tamperature: 32F to 122F (0C to 50C)
Storage Temperature: -4F to 140F (-20C to 60C)
Dimensions: 6-7/16 x 3-1/8 x 1-3/8 inches (163 x 80 x 35 mm)
UPDATE: I just done some checking with this meter. It seems the voltage/ohms are working ok, but can't seem to get the continuity buzzer to work. This units been in the dresser drawer for many, many years and not sure if a problem developed just from laying around or not? It had no battries in it during storage so there is no battery leakage. But it does seem to have a small problem somewhere. Is it the switch, dirty or something else? So I do know the volt/ohms seem to be working, don't know about anything else other then the buzzer.
