It adds apparent-power measurement and programmable upper/lower limit alarms on voltage, apparent power and other parameters — built for go/no-go production and QA testing. It is built for bench and in-rack power measurement on power-supply, converter and appliance-energy work, with RS-232 and RS-485 for datalogging and integration into automated test. Choosing Your Model — UTE9800+ Series The UTE9800+ name covers three distinct compact power meters. Compare the full series before selecting: Model What Sets It Apart Measurement V / A Range UTE9802+ AC / DC / AC+DC True RMS True power, V, A, W, PF, Hz 3V – 600V / 0.5mA – 20A UTE9806+ Apparent power + V / PF alarm limits V, A, P, VA, PF, Hz, Vpeak, Apeak 0.5V – 600V / 0.05mA – 10A UTE9811+ 50th-order harmonic analysis (PLL) V, A, W, PF, Hz, THD, CF 3V – 600V / 5mA – 20A The three UTE9800+ models are not a progression — each is a distinct instrument chosen by what you need to measure: mixed-mode true RMS (9802+), limit/alarm testing (9806+), or harmonic and distortion analysis (9811+). For single-phase high-voltage bench measurement or three-phase work, see the UTE310 Series (600 V / 1000 V single-phase) and the UTE323 Series (3-channel three-phase) — distinct higher-tier instrument lines. Key Features Apparent-power measurement (VA) Programmable V / VA / PF upper-lower limit alarms Peak voltage and peak current capture 0.5V – 600V / 0.05mA – 10A measurement range, to 1W – 6kW Voltage resolution 0.01V; current resolution 0.01mA Measurement bandwidth 40Hz – 400Hz RS-232 and RS-485 for datalogging and ATE integration 4.3-inch LCD display UNI-T UTE9806+ Details Apparent Power + Programmable Limit Alarms The UTE9806+ measures apparent power (VA) alongside true power and adds programmable upper/lower limit alarms on voltage, apparent power and power factor — a stand-alone go/no-go decision at the meter, with no host PC required. RS-232 / RS-485 Communication Both RS-232 and RS-485 are standard, with SCPI and Modbus support, for datalogging and integration into multi-drop production-line monitoring or an automated test framework. Compact Bench / In-Rack Form Factor The compact chassis fits a test bench or an instrument rack and leaves the front-panel reading clear for V, A, W, PF and frequency at a glance during a measurement run. Applications Production Go/No-Go Testing Programmable upper/lower limit alarms on voltage, apparent power and PF make the UTE9806+ a pass/fail station for end-of-line power testing without a host PC in the loop. Power-Supply QA Apparent-power and peak capture characterize loading and inrush behaviour on power-supply and converter QA. Accessories and Family Options UTE-series test cables and the UTE-M01-US North-American test fixture support safe connection to standard plug loads. Frequently Asked Questions How does the UTE9806+ differ from the other UTE9800+ models? Each UTE9800+ model is a distinct instrument: the UTE9802+ adds AC/DC/AC+DC true-RMS modes, the UTE9806+ adds apparent power and limit alarms, and the UTE9811+ adds 50th-order harmonic analysis. They are chosen by measurement need, not as a tier progression. Does it have a computer interface? Yes — RS-232 and RS-485 with SCPI and Modbus support, for datalogging and automated test. Is this a three-phase meter? No. The UTE9800+ models are single-phase (1P2W). For three-phase measurement, see the UTE323 Series.
