UT8804E | 4.8 Digit Advanced-Series Bench Digital Multimeter
Overview
The UT8804E is a 4.8-digit True RMS auto-ranging bench digital multimeter with 59,999-count resolution, 0.025% DC voltage accuracy, and a 4.3-inch color TFT display. It sits at the intersection of affordability and serious measurement capability — precise enough for R&D characterization work, yet practical enough for daily production testing. The UT8804E measures DC/AC voltage (True RMS), DC/AC current (True RMS), 2-wire and 4-wire resistance, capacitance, frequency, temperature (K-type thermocouple), diode, and continuity.
Where the UT8804E stands apart from lower-tier bench DMMs is its combination of a graphical TFT display, data recording with trend visualization, pass/fail comparison mode, and built-in math functions (dB, dBm, min/max, statistics). These features make the difference between a meter you read and a meter you work with — particularly in environments where you need to document results, catch intermittent faults, or maintain production test limits. Connectivity via USB supports data logging and PC-based remote control.

Key Features
- 4.8-Digit Resolution (59,999 Counts) — 0.025% DC voltage accuracy bridges the gap between general-purpose meters and lab-grade instruments.
- True RMS AC Measurement — Accurate readings on non-sinusoidal waveforms from switching supplies, VFDs, and other complex loads.
- 4.3-Inch Color TFT Display — Clear numeric readouts, function indicators, trend graphs, and statistical data — all visible at a glance.
- 11 Measurement Functions — DC/AC voltage, DC/AC current, 2-wire and 4-wire resistance, capacitance, frequency, temperature (K-type), diode, and continuity.
- 4-Wire Resistance — Dedicated sense terminals eliminate lead resistance from low-resistance measurements for accurate results.
- Pass/Fail Comparison Mode — Set upper and lower limits for automated go/no-go testing on the production line.
- Data Recording with Trend Graph — Capture measurements over time and visualize trends on the TFT to identify drift, intermittent faults, or thermal effects.
- Math and Statistics — Built-in dB, dBm, min/max, average, and standard deviation for real-time analysis without external software.
- USB Connectivity — Data logging and remote control via USB interface.
High-Resolution TFT Display
The 4.3-inch color TFT is a meaningful upgrade over the LCD displays on the UT8802E and UT8803E. Beyond larger, clearer digits, the TFT renders graphical trend data, bar graphs, and statistical summaries — information that helps you understand what the measurement is doing over time, not just what it reads right now. Function indicators, range, and measurement mode are all visible without cycling through menus.

Data Recording and Trend Analysis
Record measurements over time with configurable sample intervals and view the results as a graphical trend directly on the TFT. This is where the UT8804E earns its keep in production environments — you can watch a voltage rail for drift during burn-in, catch an intermittent current spike that only happens under thermal stress, or log a full test sequence and scroll back through the data. Results can be transferred to a PC via USB for documentation or further analysis.

Pass/Fail Production Testing
Set upper and lower limits for any measurement function and the UT8804E flags each reading as pass or fail — audible and visual. This turns the meter into a production test station for verifying resistor values, checking capacitor tolerances, validating power supply output, or any repetitive measurement task where you need a quick go/no-go decision. Combined with the statistics function, you can track yield and measurement distribution across a batch without exporting data.

Built-In Statistical Analysis
The statistics function tracks min, max, average, and standard deviation in real time as you take measurements. This is valuable for component screening — measure a batch of resistors and immediately see the spread — or for characterizing a circuit's behavior under varying conditions. The dB and dBm math functions add signal-level conversion for audio and RF work. All of this runs on the instrument itself, with no PC or external software required.

Professional Applications
- Production Test and QA — Pass/fail comparison mode and statistical tracking for efficient go/no-go testing and batch characterization on the production line.
- Component Characterization — 4.8-digit resolution with 4-wire resistance for accurate evaluation of resistors, capacitors, and other passive components.
- Power Supply Testing — Data recording and trend display for monitoring voltage regulation, load response, and ripple during development and validation.
- Field Service and Repair — True RMS, auto-ranging, and a clear TFT display make it effective for diagnosing faults in industrial and commercial equipment.
- R&D Lab — Math functions, data recording, and USB connectivity provide the tools for design validation without the cost of a 5.5 or 6.5-digit instrument.
Frequently Asked Questions
What is the DC voltage accuracy of the UT8804E?
The UT8804E specifies 0.025% DC voltage accuracy with 59,999-count (4.8-digit) resolution.
Does the UT8804E support 4-wire resistance measurement?
Yes. Dedicated sense terminals on the rear panel provide 4-wire (Kelvin) resistance measurement, which eliminates test lead resistance for accurate low-resistance results.
Can I log data from the UT8804E to a PC?
Yes. The USB interface supports data transfer and SCPI remote control. The instrument also records data internally with on-screen trend graph display.
How does the UT8804E compare to the UT8805E?
The UT8805E adds 5.5-digit resolution (199,999 counts vs. 59,999), dual display for monitoring two parameters simultaneously, RS-232 and LAN connectivity in addition to USB, and 100 kHz AC bandwidth. The UT8804E offers strong value for users who need TFT display, data recording, and pass/fail testing without the premium for dual display and higher resolution.
What thermocouple types does the UT8804E support?
The UT8804E supports K-type thermocouples via the rear panel thermocouple input.
