1. Press “REL”, to measure the relative value: “REL” appears on the display, the auto range mode will
be changed to manual range mode. Press again, and “REL” disappears, you return to auto range
mode. NB: the meter cannot go back to auto range mode whilst in” Hz” measurement, and will not
measure the relative value
