UNI-T UT33D Multimeter Review | Features

1- Display

The UNI-T UT33D Multimeter provides an incredibly detailed look into whatever task or function it is being used for. It displays a total of 1999 digits on its LCD screen and is designed to update around two and a half times every second. 

This display is normally quite reliable, but it does have lower limits: readings will be accurate down to 2.4 volts. However, signals below may present as inaccurate or as “overflow” (OL) before the battery symbol appears in the display at 2.3V. 

Instability of the display can be detected before this, from 1.6V upwards, so bear this in mind when using your UNI-T UT33D Multimeter!

2- Volt And Frequency Measurements

The UNI-T UT33D multimeter is an excellent device for measuring volts and frequencies. It has a 5V AC reading 5% down at 3kHz and 10-11Mohm input impedance on DC and 10Mohm on AC. 

Additionally, if the voltage exceeds 1 volt, its mV DC input impedance will drop to 3kOhm. This device is perfect when reliable, accurate readings are necessary.

3- Current Measurement

The UNI-T UT33D multimeter is a great choice regarding current measurement. It sports a 10A range fused with a 10A/250V 5x20mm fuse and an mA range with its own 0.2A/250V 5x20mm fuse. 

This multimeter also has an audible alarm at 10A or above, making detecting your circuit’s overload easier. There is no need to monitor the device continuously; let the alarm do this for you!

4- Ohm, Continuity, Diode And Capacitance Measurements

The UNI-T UT33D Multimeter is a great tool for measuring ohm, continuity, diode and capacitance. Its open voltage reading is 1.0V, while current readings are 270uA in 200/2000ohm, 75uA in 20k, 9uA in 200k, 0.9uA in 20M and 200M. 

This multimeter also offers fast Continuity measurement – it takes only approximately 20ms to take it- and emits a beep when the resistance drops below 31ohm. 

Furthermore, this device’s information on the Diode range uses 2.2V with max. display being 1.999V at 0.08mA, and its max. current is 0.9mA when short-circuit is detected for reliability and accuracy purposes. 

The UNI-T UT33D Multimeter is a great choice for various measurement needs!

5- Standard Probes

UNI-T’s UT33D Multimeter Standard Probes are a great addition to any technician’s toolkit. The probes have a resistance of 74mOhm, making them much more accurate than typical probes. 

Although the probe wire is thin at just 89cm long, they are sturdy and dependable when measuring precision voltage readings. 

With their standard size and design, these probes will fit snugly into the multimeter for quick and easy changes. Whether you’re a novice or an experienced professional, these quality probes will save you time and allow you to get accurate results quickly.

6- Backlight
