Detailed description
Precision Engineering for Tight Spaces
The UT210 series is defined by its “Mini” form factor. Unlike traditional bulky clamp meters, the UT210 is small enough to navigate through a dense “spaghetti” of wires in a fuse box. The series uses high-speed auto-ranging and a fast sampling rate (2–3 times per second) to provide instant feedback, while the True RMS technology ensures accurate readings even when testing “dirty” power from inverters or switching power supplies.
Model Comparison & Key Features:

| AC Current | Up to 200A | Up to 200A | Up to 100A |
| DC Current | No | Yes (200A) | Yes (2A / 20A / 100A) |
| Resolution | 100mA | 100mA | 1mA (on 2A range) |
| Voltage (AC/DC) | No | Yes (600V) | Yes (600V) |
| Temperature | No | Yes (-40°C to 1000°C) | No |
| VFC Filter | No | No | Yes (for motor drives) |
Key Technical Pillars:
-
The “Zero” Function: Crucial for DC current measurement. Because DC clamps are sensitive to the Earth’s magnetic field, the one-touch ZERO button allows you to calibrate the meter instantly before taking a reading.
-
VFC (Variable Frequency Control): Found on the UT210E, this low-pass filter ignores high-frequency noise, allowing you to accurately measure the output of Variable Frequency Drives (VFDs) and motor controllers.
-
Non-Contact Voltage (NCV): The tip of the clamp acts as a sensor; as you get closer to a live AC wire, the meter beeps and flashes a red LED, allowing for quick “go/no-go” safety checks without touching a wire.
-
Rugged & Safe: Built to CAT II 600V / CAT III 300V safety standards. The housing features a rubberized over-mold for grip and impact resistance.
-
“Hackability”: In the enthusiast community, the UT210E is famous for having a modifiable EEPROM, allowing advanced users to upgrade it from a 2000-count to a 6000-count meter.
Technician’s Note: If you are an automotive tech or electronics hobbyist, get the UT210E. Its 2A range is sensitive enough to find a 50mA parasitic drain that would be invisible on almost any other clamp meter.
