-AutoCheck
This innovative AutoCheck
based on the input via the test leads.
●With no input, the meter displays “Auto” when it is ready.
●With no voltage signal but a resistance below 6MΩ is present, the meter displays the resistance value. When
below 25Ω is present, the meter AM-47 produces a continuity beep tone.
●When a signal above the threshold of DC 1.2V or AC 1.5V up to the rated 600V (450V for AM-45) is present; the
meter displays the appropriate voltage value in DC or AC, whichever larger in peak magnitude.
●Overload-Alert Feature: When above rated 600V (450V for AM-45) is present; the meter displays “OL” with a
warning beep tone. Disconnect the test leads from the signal immediately to avoid hazards.
Note:
*Range-Lock Feature: When a measurement reading is being displayed in AutoCheck
SELECT button momentarily 1 time can lock the function-range it was in. The LCD annunciator “
off. Range-lock can speed up repetitive measurements. Press the SELECT button momentarily again to return to

*Hazardous-Alert: When making resistance measurements in AutoCheck
voltage readings alerts you that the part under test is still energized.

fact, more similar to that of most traditional analog multimeters. “LoZ” will display on the LCD to remind the users
in such cases. Although not likely, if such impedance might damage your circuits, use the common impedance
(Hi-Z) voltage mode (AM-47 and AM-42 only) for making voltage measurements on them.
