UNI-T UT8804E Advanced-Series Bench Digital Multimeter is a 4⅚-digit auto-ranging True-RMS meter with 0.025% basic DC voltage accuracy, a 59,999-count display and a 4.3in TFT-LCD with digitized analog bar graph.

Data recording, statistical analysis, trend-chart visualization, and Pass/Fail batch comparison are built in. For R&D bench validation, burn-in monitoring, and small-batch quality control where a basic 4½-digit meter lacks the recording-and-statistics workflow but a 6½-digit unit would be overkill, the UT8804E delivers measurement, logging, and analysis in one instrument. Thermocouple temperature measurement, multiple parameters per measurement function and USB-Device PC connectivity are standard.

• 4⅚-digit, 59,999-count display — 0.025% basic DC voltage accuracy at the tier price point.
• True-RMS AC measurement — accurate readings on non-sinusoidal waveforms (switching supplies, motor drives, PWM, dimmed loads).
• Auto-ranging — across voltage, current, resistance, and capacitance functions, reducing operator workflow friction.
• Thermocouple temperature measurement — range -40°C to 1000°C.
• Data recording with statistics and trend-chart display — Pass/Fail comparison for batch device testing.
• USB-Device PC connection — included software for historical-data viewing and trend monitoring.

UNI-T UT8804E Details

4⅚-Digit Display and 0.025% Accuracy

The UT8804E delivers a 4⅚-digit 59,999-count display with 0.025% basic DC voltage accuracy. DC voltage resolution is 0.001 mV and DC current resolution is 0.01μA — covering the precision needed for component validation, prototype bring-up, and general bench measurement. Resistance resolution is 0.01Ω.

Measurement Function Coverage

Measurement coverage includes AC/DC voltage, AC/DC current, resistance, capacitance, diode, continuity, frequency, duty cycle, temperature (thermocouple). Capacitance measurement extends to 60 mF. Frequency counter range is 60 Hz – 60 MHz.

True-RMS AC Measurement

True-RMS AC measurement delivers correct readings on distorted, non-sinusoidal waveforms — switching-mode power supply outputs, motor-drive currents, dimmed lighting loads, PWM signals — where an average-responding meter would read low. AC voltage and AC current measurements are both True-RMS.

Data Recording and Trend Analysis

Data recording captures historical measurements with real-time access to the current sample count, recording duration, extreme values, and averages. Recorded data renders as both statistical summary and trend chart; the cursor on the trend chart returns the value at a specific time point, useful for isolating anomalies in time-varying signals.

Multiple Parameters per Measurement Function

For each measurement function, the UT8804E exposes multiple parameter selections — for example, capacitance measurement can also display dissipation factor (D) or quality factor (Q) as a secondary parameter. The dual-parameter readout reduces function-key presses on multi-step measurement tasks and keeps both values visible during recording.

Pass/Fail Comparison for Batch Testing

Pass/Fail comparison sets a tolerance window around an expected value; readings outside the window trigger an audible alarm and a visual indicator. For batch production-test work — incoming component inspection, finished-board QC, post-burn-in verification — Pass/Fail flagging removes the operator-attention burden of reading the numeric display on every part.

Max / Min / Average Statistics with Timestamps

Maximum, minimum, and average value statistics track measurement extremes across a batch or time window. Each extreme reading is timestamped, so the trend chart cursor can return both the value and the moment it occurred — useful for isolating intermittent events in long-running tests.

Temperature Measurement

Thermocouple temperature measurement covers the range -40°C to 1000°C with built-in cold-end compensation. Suitable for component-thermal-test, environmental monitoring, and process-temperature verification.

Connectivity and Remote Control

USB-Device connection to a host PC enables real-time historical-data viewing, trend-chart display, and configuration backup through the included software. For workbench logging and remote monitoring of long-running tests where a separate data logger would be overkill, USB-Device provides the path.

Applications

R&D Bench Validation

• 4⅚-digit measurement on prototype boards, switching-supply outputs, and sensor circuits.
• Data recording during burn-in or temperature-cycle testing with trend-chart visualization.
• Maximum/minimum statistics for capturing intermittent events during long-duration tests.
• Component-thermal monitoring via thermocouple input.

Small-Batch Quality Control

• Pass/Fail batch acceptance testing with audible alarm on out-of-spec readings.
• Statistical summary across a production batch (max, min, average, sample count).
• Multi-parameter validation within a single measurement function via secondary parameter readout.
• USB-Device connection to a host PC for measurement logging and historical-data review.

University and Vocational Teaching Labs

• Mid-tier benchtop measurement instruction for second-year electronics and electrical engineering programs.
• Measurement-fundamentals coursework covering recording, statistics, and trend visualization.
• Capstone project measurement with True-RMS AC and Pass/Fail flagging.
• Cost-effective stocking across multi-bench classroom installations.

FAQ's

How does the UT8804E compare to other models in the UT8800E series?

The UT8804E is the mid-tier Advanced model: 4⅚-digit precision with True-RMS, auto-ranging, a 4.3-inch TFT-LCD, data recording with trend-chart display, and Pass/Fail batch comparison. It sits between the Classic UT8803E and the Performance-cohort UT8805E. If your work needs SCPI automation, fast reading rates, or four-wire resistance, step up to UT8805E or UT8806E.

Can I connect the UT8804E to a PC for data logging?

Yes. The USB-Device port connects the UT8804E to a host PC running the included software, which provides real-time historical-data viewing, trend-chart display, and configuration backup. The software is included free of charge; firmware updates over the product's lifetime are free.

Is the UT8804E factory-calibrated, and how often does it need recalibration?

Yes — every UT8804E ships with a factory calibration certificate. The recommended recalibration interval is once per year for metrology-traceable measurement applications. For routine workbench use where the meter is being used for relative comparisons or go/no-go checks against known references, longer intervals are acceptable. Recalibration is performed through Uni-Trend or an accredited third-party calibration laboratory.

What probes and accessories ship with the UT8804E?

The UT8804E ships with the standard probe and lead set appropriate to its measurement range, a power cord, the USB-Device cable for PC connection, the included software disc or download link, a user manual, and the factory calibration certificate.
