Features an extended measurement function set that includes inductance to 100 H and capacitor D/Q parameters in addition to the standard voltage, current, resistance, capacitance, diode, continuity, frequency, and temperature functions.
For electronics labs and service-bench work that needs reliable component characterization beyond basic resistance and capacitance — transformer winding inductance, motor stator verification, resonant-circuit Q measurement, RF choke validation — the UT8803E delivers the function coverage of a dedicated LCR-light meter inside a general-purpose bench DMM. Thermocouple temperature measurement and USB-Device PC connectivity are standard.
The UT8803E delivers a 3⅚-digit 5,999-count display with 0.3% basic DC voltage accuracy. DC voltage resolution is 0.01 mV and DC current resolution is 0.1μA — covering the precision needed for component validation, prototype bring-up, and general bench measurement. Resistance resolution is 0.1Ω.
Measurement coverage includes AC/DC voltage, AC/DC current, resistance, capacitance, diode, continuity, frequency, duty cycle, temperature [thermocouple], inductance to 100 H, D/Q parameters. Capacitance measurement extends to 60 mF. Frequency counter range is 600 Hz – 20 MHz.
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.
Inductance measurement to 100 H covers transformer windings, motor stator inductance, RF choke verification, and general inductor characterization. The EQR key during capacitance or inductance measurement displays D [dissipation factor] and Q [quality factor] — useful for assessing capacitor quality and inductor self-resonance behavior without a dedicated LCR meter.
The Reference Value [REL] function captures a baseline reading and displays subsequent measurements as deviations from that baseline. Combined with max/min statistics, this supports relative-comparison workflows useful for batch screening, drift studies, and component matching.
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.
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.

The UT8803E is the auto-ranging 3⅚-digit Classic model. It adds True-RMS, auto-ranging, inductance to 100 H, and D/Q parameter measurement that the UT8802E lacks, while keeping the entry-tier price point. For 4⅚-digit precision with data recording and Pass/Fail, see the UT8804E. For SCPI automation and 5½–6½-digit precision, see UT8805E and UT8806E.
Yes. The USB-Device port connects the UT8803E 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.
Yes — every UT8803E 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.
The UT8803E 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.
