UNI-T UTE9802+ Digital Power Meter

Description

UNI-T UTE9802+ Digital Power Meter The UNI‑T UTE9802+ is an economical, portable digital power meter that combines multiple measurements voltage, current, active power, apparent power, power factor, and frequency into a single handheld instrument. Its VA‑style “broken‑code” display presents numeric data and status icons clearly, while a robust 32‑bit MCU and high‑speed A/D converter ensure fast, accurate readings. True‑RMS measurement lets the UTE9802+ handle complex waveforms full‑wave, half‑wave, and irregular signals alike making it ideal for both AC and DC testing. It supports AC, DC, and combined AC+DC (T‑RMS) modes over a wide input span (3 V to 700 V; 0.5 mA to 24 A), so you can tackle everything from battery‑powered circuits to high‑voltage mains. Built‑in auto/manual ranging and a selectable averaging filter stabilize readings on fluctuating loads. Upper/lower‑limit alarms (audible and visual) aid batch testing, while RS‑232/RS‑485 with SCPI/Modbus makes remote data logging and PLC integration straightforward. Rugged silicone‑protected feet guard against bumps and drops, and full‑size stands let you position the meter hands‑free on a workbench or test rack. Features: VA‑style broken‑code LCD display with intuitive status icons. Multi‑window simultaneous readout of V, A, W, PF/Hz. AC, DC, and AC+DC (T‑RMS) measurement modes (UTE9802+ only). True‑RMS readings for accurate tracking of complex waveforms. Auto and manual range switching on both voltage and current channels. Selectable moving‑average filter (8/16/32/64 samples) to stabilize readings. User‑settable upper/lower limit with sound‑and‑light alarm. RS‑232 and RS‑485 communications supporting SCPI and Modbus protocols. Compact, portable design with silicone corner protection and fold‑out stands.
