Frequently Asked Questions

How does the dual-display functionality benefit electrical testing?

The dual-display functionality allows simultaneous monitoring of voltage and current, streamlining power analysis and load testing that would otherwise require multiple measurement steps or instruments. This capability significantly reduces testing time while providing more comprehensive information about system performance, particularly valuable when diagnosing intermittent issues or validating proper operation under varying load conditions.

What advantages does the enhanced low pass filter provide?

The enhanced low pass filter with 1kHz, 3dB attenuation provides superior filtering for variable frequency drive measurements compared to basic filters. This specialized filtering eliminates high-frequency carrier signals while preserving essential waveform characteristics, enabling accurate voltage readings on modern electronic drive systems that operate at higher switching frequencies. The result is more reliable diagnostics on sophisticated motor control systems.

Why are faster sampling rates important for industrial applications?

The accelerated 5 times per second measurement sampling and 20 times per second analog bar update provide more responsive readings for dynamic systems and transient events. These faster refresh rates help capture short-duration phenomena like motor inrush current, load variations, and intermittent faults that might be missed with standard sampling rates. This responsiveness is particularly valuable when troubleshooting complex industrial systems with rapidly changing conditions.

How does the 3-phase sequence test function help prevent equipment damage?

The 3-phase sequence test function verifies proper phase rotation in three-phase systems, which is critical when installing or reconnecting motors. Incorrect phase sequence causes reverse rotation that can damage equipment, break mechanical couplings, and disrupt processes. The UT219DS provides clear indication of proper phase rotation, preventing costly mistakes during installation and maintenance procedures on three-phase equipment.

What is the warranty period for the UNI-T UT219DS?

UNI-T provides a 12-month warranty on the UT219DS, covering manufacturing defects and component failures under normal use conditions.
