UT8805E | 5.5 Digit Performance-Series Bench Digital Multimeter
Overview
The UT8805E is a 5.5-digit True RMS auto-ranging bench digital multimeter with 199,999-count resolution and 0.015% DC voltage accuracy. It 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. The dual-display 4.3-inch TFT shows two parameters simultaneously — for example, voltage and current on a power supply under test — eliminating the need to switch functions back and forth.
The UT8805E is built for demanding R&D, calibration, and production test applications where 4.5-digit meters lack the resolution to distinguish meaningful differences. Additional capabilities include math functions (dB, dBm, min/max, statistics), pass/fail comparison mode, data recording with trend graph display, and 100 kHz AC bandwidth. Connectivity via USB, RS-232, and LAN supports data logging, remote control, and automated test system integration.

- Connectivity — USB, RS-232, and LAN for data logging, remote control, and automated test integration.
Dual Display for Simultaneous Monitoring
The dual-display capability lets you monitor two measurement parameters at the same time — for example, voltage and current on a power supply under test, or resistance and temperature during a thermal characterization. This eliminates the need to switch functions back and forth and reduces the risk of missing transient events on either parameter. The 4.3-inch TFT provides clear, high-contrast numeric readouts with function indicators for both channels.

Math Functions and Statistical Analysis
Built-in math functions include dB and dBm conversion for RF and audio measurements, as well as min/max tracking, average, and standard deviation calculation. These run in real time on the measurement stream — useful for characterizing component drift, evaluating noise on a power rail, or establishing statistical process control baselines during production testing. No external software required for basic statistical analysis.

Comprehensive Measurement Modes
With 199,999-count resolution across all functions, the UT8805E handles precision bench work that exceeds the capabilities of 4.5 or 4.8-digit meters. Temperature measurement supports both K-type and J-type thermocouples for thermal profiling. The 4-wire resistance mode provides accurate low-resistance readings by eliminating lead resistance — critical when measuring contact resistance, PCB trace resistance, or low-value precision resistors.

Data Recording and Trend Analysis
Record measurements over time with configurable sample intervals and view the results as a graphical trend on the TFT display. This makes it easy to spot drift, intermittent faults, or temperature-dependent behavior during long-duration tests. Recorded data can be transferred to a PC via USB or RS-232 for further analysis. The pass/fail comparison mode lets you set upper and lower limits for automated go/no-go testing, streamlining production workflows.

Frequently Asked Questions
What is the DC voltage accuracy of the UT8805E?
The UT8805E specifies 0.015% DC voltage accuracy with 199,999-count (5.5-digit) resolution.
Does the UT8805E 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 low-resistance measurements.
Can I automate measurements with the UT8805E?
Yes. The USB, RS-232, and LAN interfaces support SCPI commands for remote control and data acquisition. For GPIB connectivity, see the UT8806EG which adds a built-in IEEE-488 interface.
What thermocouples are supported for temperature measurement?
The UT8805E supports K-type and J-type thermocouples via the rear panel thermocouple input.
How does the UT8805E compare to the UT8806E?
The UT8806E offers 6.5-digit resolution (1,999,999 counts) vs. the UT8805E's 5.5 digits (199,999 counts), with correspondingly higher accuracy (0.0035% vs. 0.015%). The UT8806E also adds USB mass storage for data export and 300 kHz AC bandwidth vs. 100 kHz. Both have dual display, 4-wire resistance, and data recording.
