Fluke PQ400 Operating Manual

PQ400

PQ Window

Voltage/Current Measurement Feed-Through

Device for Electrical Enclosures

Instructions

PQ Window (the Product) is an accessory that mounts to the
flat surface of a Type 12 electrical enclosure (derate to Type 1
during measurements). When the Product is installed and signal
feeds connected, you can safely perform voltage and current
measurements from outside the enclosure.

Standard 4 mm safety sockets on the front provides access
to the three phases (A/L1, B/L2, C/L3), Neutral N, and Earth/
Ground for voltage measurements. The voltage outputs
support instruments that are powered from the measurement
line with a maximum power of 100 VA.

The Product supports current measurement with Fluke
intelligent current sensors (iFlex1500-12, iFlex 3000-24,
i40S-EL and i400S-EL). Go to www.fluke.com
compatible accessories.

The 354x FC, 173x Power, and 174x Power Quality Loggers
automatically read the sensor information, such as, the type,
serial number, scale factor, and phase angle compensation.
Use the optional adapter kit to connect instruments and
current sensors that have BNC connectors.
