Figure 1: Fluke 43B - Power Quality Analyser

1 Description

The Fluke 43B is our main measuring device in the lab. It has 2 inputs: 1 voltage using test leads and 1 current using a suitable current probe. It is powered by either it’s Rechargable battery or plugged in using its wall adaptor.

1.1 Setup

The Fluke 43B with the 80i-110s AC/DC current probe will mainly be used to monitor and measure the voltages and currents in the circuit. The meter will be powered by plugging it into the power adapter provided. The meter should be setup with the standard voltage leads and 4mm probe tips on channel 1 and the 80i-110s AC/DC current probe on Channel 2. Turn on the current probe to the 100mV/A setting (green light should come on, if the light turns off at any point during the lab request to have the battery replaced) and Configure the meter to use test leads for channel 1 and 100mV/A for channel 2. Zero the current probe by turning the black dial until you get a dc current reading as close to zero as possible.

2 Measurements

2.1 Volts/Amps/Hertz

  • Shows the Voltage and Current Waveform (uses a PLL to measure approximately 3 cycles of the fundemental)
  • Includes the RMS Voltage and Current
  • Shows the fundemental frequency
  • Also shows the Crest Factor (CF)

2.2 Power

  • Has both a 1ph and 3ph mode
  • Shows both the measured Voltage and Current Waveforms
  • Displays the Real, Reactive and Apparent Power Values
  • Shows the Power Factor and Total Harmonic Distortion

2.3 Harmonics

  • Displays the Voltage, Current or Power Harmonics
  • Displays the Total Harmonic Distortion
  • Can obtain the Magnitude and Phase of each Harmonic

2.4 Scope

  • Works like a 2 channel oscilloscope
  • Can do automatic measurements for several quantities
