UNI-T UT191T Multimeter Review | Features

1- Display

Have you ever had those moments when you’re deep in the middle of a project, and suddenly your trusty multimeter shows signs of distress? The UNI-T UT191T Multimeter Display has got your back. Its display starts to fade at around 3.4V and disappears at 2.2V, but don’t worry. 

Your readings will still be accurate until the display fades. Plus, with a good viewing angle and a display update of around three times per second, you won’t miss a beat. 

And if you still are working with some juice left, the battery symbol shows empty at 6.2V, giving you plenty of warning before running out of power.

2- True RMS/Peak value measurement

Have you ever needed help getting accurate measurements with your current multimeter? The UNI-T UT191T might be the solution to your problem. 

With its True RMS/Peak value measurement feature, this multimeter can provide you with precise readings to help identify any electrical issues or inconsistencies. Don’t settle for less regarding your tools – upgrade to the UT191T and experience the difference firsthand.

3- Auto Backlight

The UNI-T UT191T Multimeter is an impressive tool that makes it easy for technicians to measure various electrical parameters easily. It has a convenient backlight feature that automatically turns on when in dimly lit environments, allowing for easy data readability even without light. 

The bonus of a flashlight also makes it versatile for use in areas with poor visibility. It’s important to note that the backlight and flashlight will begin to fade at 4V and disappear completely at 2.7V. 

At that point, the auto power off feature will take over and shut down the flashlight. This feature-rich device is necessary for any professional needing a reliable and efficient multimeter.

4- LoZ AC Measurement

The UNI-T UT191T Multimeter is a top-of-the-line tool every electrician or engineer would love to have in their arsenal. It boasts a remarkable feature differentiates it from other multimeters available in the market – the LoZ AC measurement feature. 

LoZ stands for Low input impedance, meaning the device uses a lower resistance (300kOhm) to measure voltage. This means that the UT191T’s measurement range is always 600VAC, no matter what. 

This feature is particularly helpful when measuring voltage in circuits with electronic ballasts or dimmer switches, where regular multimeters can potentially register false readings due to leakage currents. 

The UT191T’s LoZ AC measurement feature solves this problem by providing accurate daily readings.

5- Volt And Frequency Measurements

The UNI-T UT191T Multimeter offers accurate readings for both voltage and frequency measurements. One particularly helpful feature is the MilliVolt range, which remembers the last AC/DC setting for added convenience. 

However, it’s important to note that the 1V AC reading is 5% down at 2kHz, and the 7V AC reading is 5% down at 800Hz when LPF is active. The AC frequency range requires a zero crossing, while the frequency input can handle at least +/-9.8V offset at 0.1VAC and has a range of 1.1Hz to 1.1MHz. 

Ultimately, with its vast frequency range and advanced capabilities, the UNI-T UT191T Multimeter is a great choice for professionals seeking accurate voltage and frequency measurements.

6- Current Measurements

The UNI-T UT191T Multimeter is reliable for those requiring precise current measurements. The device offers a 20A range with an audible alarm that sounds above 10A, ensuring that users are alerted if there is a surge in current flow. 

Additionally, the current ranges remember whether AC or DC settings were used, making it easier to switch between the two. The 20A range is fused with an 11A/1000V 10x38mm fuse, while the mAuA range has a 0.6A/600V 6.3x32mm fuse. 

Furthermore, the peak option can be selected for AC. Whether you’re a professional or a DIY enthusiast, the UNI-T UT191T Multimeter is a must-have for your toolkit.

7- Ohm, Continuity, Diode and Capacitance Measurement

The UNI-T UT191T Multimeter is a versatile tool that can measure ohm, continuity, diode, and capacitance. When measuring an ohm reading of 100 ohms, it takes approximately 2.8 seconds to get a reading. 

The ohm voltage is 1.0V when open and 0.33mA when shorted. Continuity measurements are incredibly fast, taking less than 5ms to get a reading. The meter beeps when the resistance is below 50ohm, and the voltage is 1.0V when open and 0.33mA when shorted. 

When measuring diodes, the range uses 3.2V, with a full display of 1.200V at 0.86mA. The maximum current is 1.4mA when shorted. Capacitance measurements take time, but with the UNI-T UT191T, 10uF takes roughly 2.5 seconds, while 11000uF takes approximately 6.5 seconds. 

With its impressive capabilities and reliable performance, the UNI-T UT191T is an ideal tool for those needing precise measurements.

8- Bar Graph

The UNI-T UT191T Multimeter is more than just your average device for measuring current, voltage, and resistance. It also features a bar graph that updates at the same speed as the display, giving you real-time insights into the data you collect. 

This makes it much easier to keep track of changes in electrical levels as they happen, providing more accurate results and a faster overall testing experience.

9- Protection

When it comes to choosing the right multimeter for your electrical work, protection is key. The UNI-T UT191T multimeter offers exceptional overload protection of 600V, ensuring your device won’t be damaged during a power surge. 

Plus, with input protection of 600VDC/600VAC and a CAT III 600V rating, you can trust that you are safe while taking readings. 

And don’t worry about accidental drops – the UT191T is IP65 rated and 2m drop proof. Keep your focus on the task, knowing your equipment is up to the task.

Pros:

  • High current range
  • CE/GS/cTUVus certified
  • CAT III 600V
  • IP65 waterproof
  • Suitable for use in damp and dusty environments
  • Supports accurate and precise temperature measurement

Cons:

  • Not as precise as other IP65 meters
