Volts/Amps/Hertz 

Introduction 

Volts/Amps/Hertz displays a Meter screen with important numerical measuring values. 

The related Trend screen shows the changes over time of all values in the Meter screen. 

Events such as dips and swells are listed in a table. 

Fluke 437-II

 is able to perform measurements in 400 Hz power systems (Marine, 

Aerospace, Rail, Military).  

Meter screen 

To access the VOLTS/AMPS/HERTZ Meter screen: 

c

 

MENU

 

 

 

 

d

 

ENTER

 

 

 

 

 
The Meter screen gives an overview of voltages and currents in all phases. The rms 

voltages are shown neutral-to-line and line-to-line. Also frequency and Crest Factors are 

shown. The Crest Factor CF indicates the amount of distortion: a CF of 1.41 means no 

distortion and higher than 1.8 means high distortion. Use this screen to get a first 

impression of power system performance before examining the system in detail with 

other measuring modes. The number of columns in the Meter screen depends on the 

power system configuration.  Use the up/down arrow keys to scroll the Meter screen.
