UNI-T UT33A Review | Features

1- Display

Are you looking for a reliable multimeter for your DIY projects? The UNI-T UT33A Multimeter is designed to provide accurate voltage, current, and resistance readings. However, it is important to note that the display might get unstable at 1.6V and can show overflow beforehand. 

The battery symbol will show at 2.4V, and readings will be correct to that level. The display can show OL or high readings if the voltage exceeds that. The display updates about 2.5 times per second, providing real-time information. 

With a display count of 3999, this multimeter is an excellent addition to your toolkit.I made the list of best budget multimeters you can check out.

2- Multiple Functions

If you’re looking for a multimeter that can perform multiple functions, then the UNI-T UT33A is a great option. With its rotary switch, you can choose between different voltage ranges, both AC and DC. And with the SEL/REL button, you can select AC in mV and current ranges while zeroing the capacitance range. 

Additionally, the meter has a hold/backlight button that freezes the display reading until the button is pressed again and turns on the backlight when held down. 

So whether you’re an electrician or engineer, the UNI-T UT33A can help you easily complete your tasks.

3- Volt And Frequency Measurements

The UNI-T UT33A Multimeter is an incredibly precise Volt and Frequency Measurements tool. It boasts a 1V AC reading down by only 5% at 2.5kHz, and its input impedance on DC and AC comes in at 10-11 Mohm. 

In addition, on mV AC/DC, the Multimeter’s impedance is only 2kOhm when the input voltage exceeds 1 volt – proving how effective this unit can be in even the most challenging electric environments.

4- Current Measurement

The UNI-T UT33A Multimeter offers hassle-free current measurements with its specifically designed ranges. The 10A range is equipped with a 10A/250V 5x20mm fuse, while the mA range is fitted with a smaller 0.2A/250V 5x20mm fuse for increased accuracy. 

An added feature to the 10A range is an audible alarm that goes off when the measurement exceeds 10A. 

With these stunning specifications, handling current measurements with the UT33A is an efficient and secure process that assures precision and safety. To learn more about Fluke 325, you can click here to get guidance.

5- Ohm, Continuity, Diode and Capacitance Measurements

The UNI-T UT33A is a great choice if you want a versatile multimeter. With the ability to measure ohm, continuity, diode, and capacitance, you’ll have a tool that can handle a variety of electrical measurements. 

When measuring ohm, be prepared to wait about 3.5 seconds for a 100ohm measurement. The ohm voltage is 1.0V open and 0.31mA shorted. Continuity is much faster, beeping about 20ms when resistance is below 31ohm. 

The continuity voltage is 2.1V open and 0.31mA shorted. The diode range uses 2.2V, with a max display of 1.999V at 0.07mA and a max current of 0.9mA shorted. 

Finally, a 2000uF measurement will take about 9 seconds. The UNI-T UT33A is a reliable and efficient tool for electrical measurements.

6- Backlit

The UNI-T UT33A Multimeter Backlit is a must-have tool for those serious about electrical work. With its backlight that works down to 1.6V, you can easily read measurements in low-light environments. 

And when you’re done, the backlight will turn off automatically after about 30 seconds to save battery life. The device is compact yet sturdy, making it perfect for use in tight spaces. 

Plus, with its easy-to-use interface, you will save time fumbling with complicated settings. Trust us; the UNI-T UT33A Multimeter Backlit is an excellent investment you won’t regret.
