FLUKE 434 Energy Analyzer

The Fluke 434 Energy Analyzer helps to locate, predict, prevent, and troubleshoot power quality problems in three-phase and single-phase power distribution systems. The Energy Loss Calculator function measures the fiscal cost of energy wasted due to poor power quality, which allows you to identify the most energy-wasteful areas of your facility so you can determine potential energy saving solutions. It has 600 V CAT IV/1000 V CAT III safety ratings.

dBc
dBc (decibels relative to the carrier) is the power ratio of a signal to a carrier signal, expressed in decibels. If the dBc figure is positive, then the relative signal strength is greater than the carrier signal strength. If the dBc figure is negative, then the relative signal strength is less than carrier signal strength.

Load Regulation
Load regulation is the capability to maintain a constant voltage (or current) level on the output channel of a power supply despite changes in the supply's load (such as a change in resistance value connected across the supply output).

Power Linearity
When changing the power level and measuring the differences (in dB) between actual and displayed power levels, the power linearity is ± half the span (in dB) between the maximum and the minimum value of all differences.

Settling Time
Settling time of an output device is the time elapsed from the application of an ideal instantaneous step input to the time at which the amplifier output has entered and remained within a specified error band, usually symmetrical about the final value.
