I. Overview
UT219P is a digital power clamp with fundamental frequency up to 1 kHz. This clamp meter
can be used to measure AC voltage, AC current, active power, apparent power, reactive power,
power factor, phase angle, power quality, frequency, phase sequence, total harmonic distortion,
harmonic component, etc. It has different measurement modes including single phase, three-
phase three-wire, and three-phase four-wire. Designed with Bluetooth function, measurement
data can be monitored and recorded via mobile phone and tablet, and professional report can
be generated. Featuring easy operation, stable performance, accurate measurement and more,
UT219P can be applied in multiple fields such as:
1) Measure power quality of UPS to evaluate if operation is normal.
2) Measure power factor of power system to analyze capacitive or inductive load.
3) Measure harmonic of power grid of power system, to find out harmonic issue that may
damage the load of nonlinear equipment of power grid.
4) Troubleshoot 400Hz AC power supply system of aviation and 25Hz AC power supply system
of railway.
5) Test and maintain high-power motor, centrifugal fan, centrifugal water pump, wind power
generation, solar power generation.
6) Test new energy vehicles and hybrid electric vehicles, evaluate motor efficiency, invertor
efficiency and energy consumption of driving.
II. Features
1) Completely sealed (Ip54).
2) Wide jaw opening (80mm) enables measuring current of thick conductor (Max. 75mm).
3) Category rating: CAT IV 600V AC, CAT III 1000V AC.
4) 1000V AC RMS voltage measurement, 15Hz~1000Hz frequency response range.
5) 1000A AC RMS current measurement, 15Hz~1000Hz frequency response range.
6) Ability to measure and display RMS and peak simultaneously.
7) Multiple wire connecting modes including single-phase two-wire, single-phase three-phase,
balanced three-phase wire-wire, unbalanced three-phase three-wire, balanced three-phase
four-wire, unbalanced three-phase four-wire, and more. Simple guidelines for wire connecting
places can be shown on the upper and lower displays when performing three-phase connection.
8) Wide fundamental frequency range for power measurement: 15Hz~1000Hz.
9) Ability to analyze 40th voltage and current harmonics. THD %f (total harmonic to fundamental
wave distortion), THD %r (total harmonic to full wave) and RMS of harmonic component of
each order.
10) Identify if electricity theft occurs by comparing measurement of single-phase active electric
energy of electric energy meter.
11) Detect phase sequence of motor to prevent inversed phase sequence of power supply
from causing motor to rotate inversely.
12) Via Bluetooth APP, the product can record measurement data and generate graph, table,
and report. The product has multiple functions including real-time monitoring for rapid
troubleshooting, data recording and processing, integrated management, and more, so
as to achieve integrated monitoring, maintenance and management.
