KRA-4000M
DIGITAL INSULATION TESTER
the tested through the inner switch of the meter.
Turning the function switch can exit automatically from
testing status during the process。
4.LOW RESISTANCE (CONTINUITY) MEASUREMENTS
a). Set the range switch to 400Ω/BZ Position
b). Connect the red test lead to the V Ω terminal and black
to the COM terminal.
c). Connect the tips of the test leads to both ends of the
circuit under test. read resistance in Ω on the LCD. The
two ranges(40.00/400.0Ω) can be switched automatically;
the primary display of the resistance in Ω, flashes in
synchronous with the analog bar.
d). When the impedance on circuit is below approximately
≤35Ω.It will indicate by a continuous beeper.
e) The current is from 200 to 220mA while the tested
resistance is 0Ω
f) The high voltage symbol "
primary display of ">30V" and the buzzer warns frequently
if the voltage (AC/DC) is more than 30V.
5.AC/DC VOLTAGE MEASUREMENTS
a). Set the range switch to ACV or DCV position
b). Connect red test lead to "V Ω" terminal and black test
lead to terminal "COM".
c). Connect test prods of test leads IN PARALLEL to the
circuit being measured.
d). Read the voltage value on LCD.
