Check the power LED light:
  1. If the LED is amber, the meter is in sleep mode:
    • Press any button to wake the meter.

  1. If the LED is off, the meter is either turned off or does not have power:
    • If there is a power switch on the back of the machine, check that it is set to the ON position ( | ).
    • Check that the power cable is plugged into the back of the meter and into a functioning electrical outlet.

  1. If the LED is green, and/or the machine makes noises like it is booting up when first plugged in, it may be a display issue where the contrast needs altering.
    1. Unplug the meter for 10 seconds.
    2. Hold down the number 4 button while plugging the meter back in. This will reset the contrast to the default setting.
