UT8806E | 6.5 Digit Performance-Series Bench Digital Multimeter
Overview
The UT8806E is a 6.5-digit True RMS auto-ranging bench digital multimeter with 1,999,999-count resolution and 0.0035% DC voltage accuracy. It is the highest-resolution meter in the UT8800E series, built for metrology, calibration labs, and advanced R&D applications where measurement uncertainty matters. The dual-display 4.3-inch TFT shows two parameters simultaneously, and the 300 kHz AC bandwidth covers a wider range of AC signals than the lower-tier models.
The UT8806E measures DC/AC voltage (True RMS), DC/AC current (True RMS), 2-wire and 4-wire resistance, capacitance, frequency, temperature (K/J-type thermocouple), diode, and continuity. It includes math functions (dB, dBm, min/max, statistics), pass/fail comparison mode, data recording with trend graph display, and USB mass storage for direct data export to a flash drive without a PC connection. Connectivity via USB, RS-232, and LAN supports remote control and automated test integration.

Dual Display and Real-Time Analysis
The dual-display TFT shows two measurement parameters simultaneously — voltage and current, resistance and temperature, or any other combination. Built-in statistical functions run in real time on the measurement stream: average, standard deviation, min/max tracking, and count. This supports calibration workflows where you need to observe both the value under test and the stability of the measurement over time without toggling between screens.

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 display. This makes it straightforward to identify drift, intermittent faults, or temperature-dependent behavior during burn-in, stability testing, or calibration runs. The visual trend complements the numeric statistical readout — you can see both the current value and the full history of the measurement session at a glance.

USB Mass Storage for Direct Data Export
The UT8806E supports USB mass storage — plug in a standard USB flash drive and save measurement data directly from the instrument without needing a PC connection or software. This is particularly useful in calibration labs and production environments where instruments may not be connected to a network, or when you need to quickly archive test results for compliance documentation.

Professional Applications
- Calibration and Metrology — 6.5-digit resolution and 0.0035% accuracy support traceable measurement workflows and calibration verification against lab standards.
- Component Characterization — Measure resistance, capacitance, and leakage at resolutions that distinguish between within-tolerance and marginal components.
- Power Supply Testing — Use dual display to monitor voltage and current simultaneously during load testing, regulation verification, and ripple assessment.
- Production Test — Pass/fail limits and comparison mode for efficient go/no-go testing. USB mass storage enables data archiving without PC infrastructure.
- R&D Lab — Math functions, data recording, and statistical analysis support design validation, noise characterization, and long-duration stability testing.
Frequently Asked Questions
What is the DC voltage accuracy of the UT8806E?
The UT8806E specifies 0.0035% DC voltage accuracy with 1,999,999-count (6.5-digit) resolution.
Does the UT8806E support 4-wire resistance measurement?
Yes. Dedicated sense terminals on the rear panel provide 4-wire (Kelvin) resistance measurement, which eliminates test lead resistance from the reading for accurate results in the milliohm range.
How does the UT8806E compare to the UT8805E?
The UT8806E offers 6.5-digit resolution (1,999,999 counts) vs. the UT8805E's 5.5 digits (199,999 counts), with 0.0035% vs. 0.015% DC voltage accuracy. The UT8806E also adds USB mass storage for data export without a PC and 300 kHz AC bandwidth vs. the UT8805E's 100 kHz. Both share dual display, 4-wire resistance, data recording, and math functions.
Do I need the UT8806EG for remote control?
Not necessarily. The UT8806E supports remote control via USB, RS-232, and LAN using SCPI commands. The UT8806EG adds a GPIB (IEEE-488) interface specifically for integration with legacy automated test systems that use the GPIB bus.
Can I save measurement data without a PC?
Yes. The UT8806E supports USB mass storage — insert a standard USB flash drive and save data directly from the front panel.
