Overview

1. Function Description
2. Usage Features
3. Maintenance Features

The UT219PV is a True-RMS AC/DC clamp meter specifically engineered for high-voltage photovoltaic environments, making it an indispensable tool for installation and maintenance in the solar energy field. Beyond photovoltaics, its robust capabilities extend to energy storage systems, uninterruptible power supplies (UPS), large-scale motors, and other high-voltage applications.

Function Description:

The UT219PV offers a comprehensive suite of measurement functions:

• Voltage Measurement: It can measure DC voltages up to 2500V and AC voltages up to 1500V. A specialized low pass filter (LPF) function is available for AC voltage measurements, allowing for accurate readings of composite sine signals generated by inverters and variable-frequency motors.
• Current Measurement: The device handles DC currents up to 1000A and AC currents up to 1000A using its clamp jaws. For higher AC currents, it supports an optional flex current sensor, enabling measurements up to 3000A AC. The LPF function is also applicable to AC current measurements, providing precise readings in complex electrical environments.
• Power Measurement: It is capable of measuring DC power up to 2500KW.
• Inrush Current and Peak Value (PEAK) Measurement: This feature allows for the measurement of instantaneous current at the startup of electrical appliances, capturing the maximum current over a 100ms integral.
• Resistance, Continuity, Diode, and Capacitance Measurement: The UT219PV includes standard multimeter functions for testing resistance, checking circuit continuity, evaluating diodes, and measuring capacitance.
• Temperature Measurement: It can measure temperature in both Celsius and Fahrenheit.
• Flex Current Sensor Connectivity: The meter is designed to connect with an optional UT-CS09D flex current sensor, expanding its current measurement capabilities.

Usage Features:

The UT219PV is designed for user convenience and safety across various operational scenarios:

• Dual Displays: It features dual displays that can simultaneously show different measurement parameters, such as voltage/frequency, current/frequency, or DC voltage/current alongside DC power/current.
• Data Storage: The device includes a data storage function, allowing users to save measurement data. Up to 999 sets of data can be stored internally.
• Bluetooth Connectivity: Equipped with Bluetooth, the UT219PV enables remote control and monitoring of measurement data via the "UNI-T Smart Measure" mobile application, available for both iOS and Android devices. This feature facilitates data recording, device management, report generation, and data sharing.
• Automatic Backlight: The meter offers an automatic backlight function for improved visibility in various lighting conditions.
• Auto Power Off: To conserve battery life, the clamp meter automatically turns off after 15 minutes of inactivity. This function can be disabled if continuous operation is required.
• Zeroing Function: A dedicated ZERO button allows for clearing residual readings in DC current measurements, ensuring accuracy.
• MAX/MIN/AVG Mode: Users can select to display maximum, minimum, or average values cyclically, which is useful for monitoring fluctuating measurements.
• Ergonomic Design: The meter features slim clamp jaws with a 35mm opening, making it suitable for measuring concentrated cables, inverters, and copper busbars in combiner boxes. A tactile barrier enhances user safety during operation.
• High Safety Rating: The UT219PV conforms to Double Insulation, Overvoltage CAT III 1500V/CAT IV 600V, and Pollution Degree 2 standards, ensuring safe operation in demanding environments. It also has an IP65 rating, making it suitable for outdoor use, particularly in solar arrays and wind energy systems.
• Warning Indicators: The device provides clear warnings, such as a "4" symbol for high voltage (≥30V AC/DC), "OL" for overload, and a blinking "POLARITY" symbol with red backlight and buzzer for negative DC voltages below -10V. A low battery indicator prompts users to replace batteries to maintain measurement accuracy.

Maintenance Features:

The UT219PV is designed for straightforward maintenance to ensure longevity and reliable performance:

• Battery Replacement: The device operates on two AA 1.5V batteries. The user manual provides clear instructions for safe battery installation and replacement, emphasizing correct polarity.
• General Cleaning: The case can be cleaned regularly with a dry cloth. Abrasives or solvents should not be used to prevent damage.
• Qualified Service: For any maintenance or service beyond basic cleaning and battery replacement, it is recommended to consult qualified maintenance personnel or an authorized service center to ensure the product's integrity and safety.
• Storage Recommendations: For extended periods of non-use, it is advisable to remove the batteries to prevent leakage and potential damage to the device. The meter should be stored within specified temperature and humidity ranges to maintain accuracy and functionality.
