Product Description
Our company specially launched the insulation resistance tester to
carry out insulation, absorption ratio and polarization index
withstand voltage leakage tests on the electric power equipment,
providing early accurate judgment for a series of insulation tests.
Since the charging current directly affects the insulation value
test of the large-capacity capacitive test product, so a large
charging current is required. The stronger the charging capacity,
the closer the test value of absorption ratio is to the real
value.The short circuit current of the resistance tester is greater
than 5mA, which overcomes the disadvantages of the ordinary megohm
meter, such as small short circuit current, inaccurate test and
easy interference.It adopts timely voltage and current sampling for
division operation, so the resistance value calculated by ohm's
theorem is accurate even if the voltage changes during the test.The
tester adopts advanced single chip microcomputer control process,
man-machine interface dialogue, easy to carry, easy to operate;It
is equipped with high performance large capacity rechargeable
battery, AC/DC, and under voltage protection and battery overcharge
protection.This instrument can automatically display the current
time, save the historical test data and time, providing great
convenience for the test personnel.
