1) Measuring range (Automatic function selection)
•
LoZ : 1.5 to 999.9Vdc, -1.0V to -999.9Vdc
•
LoZ
: 3Vac to 999.9Vac (50/60Hz)
• LoZΩ: 0.0Ω to 60.00MΩ
2) Measuring procedure
①
Connect the red plug of the test lead to the AutoΩ
・
V measuring
terminal and the black one to the COM terminal.
②
Set the function selector to
.
③
Apply the test pins (Red and Black) to the object to measure.
④
Read the display.
Note:
•
Range-Lock and Function-Lock Feature:
When a measurement reading is being displayed in AutoΩV
mode, press the RANGE or SELECT button to lock the range or
function it was in. Press the button repeatedly to step through
the ranges or functions.
•
Voltage Hazardous Alert:
When making resistance measurements in AutoΩV 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. Our AutoΩV mode provides low (ramp-
up) input impedance (approx. 3kΩ at low voltage) to drain ghost
voltages leaving major signal values on meter readings.
