The Metrel MD 9273, a Bluetooth-enabled addition to the Metrel multifunctional testers MI 3155, MI 3152, and MI 3325, allows for safe, remote data measurement when used together.
The multifunctional instruments can record inrush current from the MD 9273 and display the data in table or graph form. Additionally, they can generate a 128 Hz signal that the MD 9273 can filter and follow for cable tracing
As a remote probe, it can transmit data on current, voltage, power, and harmonics. Also functions as an independent instrument with enhanced accuracy, robust construction, and new features like a VFD filter.
It can precisely measure the TRMS AC leakage current of a system, identify system losses, suggest potential causes for these losses, detect signal harmonics, and conduct basic power quality tests.
