Uni T Professional Digital Multimeter UT61 Series 1000V

Uni-T UT61B+/UT61D+/UT61E+ Professional Digital Multimeters deliver true RMS precision in a compact, field-ready package. Designed for electricians, technicians, and serious electronics enthusiasts, these meters handle demanding measurements up to 1000V AC/DC with confidence, clear visibility, and safer operation.

Why this series stands out

• True RMS accuracy means reliable readings even on non-sinusoidal signals, a common reality in real-world circuits, power supplies, and automotive systems.
• High-resolution display in two tiers: 6000-count models (UT61B+/UT61D+) and an expansive 22,000-count display (UT61E+), so you can read tiny variations at a glance.
• Wide voltage and current ranges reach up to 1000V DC/AC for voltage, and up to 10A (B+) or 20A (D+/E+) for current, balancing speed and safety for a broad range of tasks from electrical troubleshooting to equipment maintenance.
• Comprehensive measurement suite including resistance, capacitance, and frequency, plus duty cycle 0.1%–99.9%, giving you a complete view of circuit behavior in one tool.
• Non-contact voltage (NCV) detection with audible and visual alarms to warn you before contact, a valuable safety feature for quick in-field checks.
• Data hold, backlight, and Max/Min/Relative modes to capture fleeting readings and compare changes over time, even in dim environments or on busy benches.
• USB communication enables data transfer and logging, so you can archive measurements, build reports, or integrate readings into your diagnostic workflow.
• Input protection and rugged construction designed for daily use in workshops, HVAC sites, and on-site electrical service.
• Diode and continuity testing help verify components quickly, while the included temperature probe (UT61D+ variant) expands your diagnostic toolkit for environments where temperature matters.

What you can measure and how it helps

• AC/DC voltage up to 1000V lets you test mains wiring, power supplies, and electronics without swapping meters. The UT61E+ variant extends performance with higher frequency capability, ideal for rapidly switching power electronics and filters.
• AC/DC current ranges up to 10A (B+) and 20A (D+/E+) support motor checks, lighting circuits, and automotive diagnostics with confidence and quick response.
• Resistance and capacitance ranges cover integrity checks on cables, resistors, and capacitors, including larger capacitances with UT61E+ for electronics and power supply work.
• Frequency and duty cycle measurements help characterize oscillators, PWM signals, and communication interfaces, so you can tune circuits and validate performance.

Who should choose the UT61 series

• Professionals performing on-site diagnostics, maintenance, and repair where up to 1000V rating is essential.
• Electronics hobbyists building and testing power supplies, filtering stages, or audio electronics that require true RMS accuracy.
• HVAC technicians and automotive technicians who need fast, reliable voltage/current checks with safety-oriented features like NCV detection.
• Lab bench users needing USB data logging and clear display counts for precise measurements and documentation.

Practical tips for optimal use

• Use the NCV function to quickly verify presence of live voltage before making contact. Listen for audible alerts and watch the indicator on-screen.
• Switch to Auto Range for most everyday measurements to simplify testing, or use Max/Min/Relative modes when comparing signals over time.
• Take advantage of the backlight in dim environments and data hold to freeze a measurement while you document results.
• Note that four 1.5V batteries (R03) are required to power the meter and are not included in the box.
• Connect test leads with proper polarity and use the included temperature probe on UT61D+ when monitoring temperature-sensitive circuits.
