The DMM Display


use images please

  • If we look at the image on the left hand side of the screen it is obvious that the DMM display is the window at the top of the device.
  • It is actually a Liquid Crystal Display (LCD) which displays both positive and negative decimals.
  • The decimal on the display does not tell us much about the actual amplitude of the signal, in order to obtain this information we must also check the range that the DMM is measuring in using the Range Selector Switches.
  • We also must know whether we are measuring a resistance, AC, DC, current or voltage using the Input Terminals and Mode Selector Switches.

  • If we look at the FLUKE DMM on the left hand side of the screen it is obvious that the DMM display is the window at the top of the device.
  • It is actually a Liquid Crystal Display (LCD) which displays both positive and negative decimals.
  • The FLUKE DMM has an automatic range function which sets the DMM range allowing us to read the amplitude straight from the display.
  • But much like the more complex DMM we must know the type of signal we are measuring: a resistance, AC, DC, current or voltage using the Mode Selector Dial.
