magnitude.
Note:
*Range-Lock and Function-Lock Feature: When a measurement reading is being
displayed in AutoCheck
TM
mode, press the RANGE or SELECT button momentarily 1 time
can lock the range or function it was in. Press the button momentarily repeatedly to step
through the ranges or functions.
*As Hazardous-Alert: When making resistance measurements in AutoCheck
TM
mode, an
unexpected display of voltage readings alerts you that the object under test is being
energized.
*Ghost-voltage Buster: Ghost-voltages are unwanted stray signals coupled from adjacent
hard signals, which confuse common multimeter voltage measurements. Our AutoCheck
TM
mode provides low (ramp-up) input impedance (approx. 3kΩ at low voltage) to drain ghost
voltages leaving mainly hard signal values on meter readings. It is an invaluable feature for
precise indication of hard signals, such as distinguishing between hot and open wires (to
ground) in electrical installation applications.
WARNING:
AutoCheck
TM
mode input impedance increases abruptly from initial 3kΩ to a few hundred
kΩ’s on high voltage hard signals. “LoZ” displays on the LCD to remind the users of being
