SAFETY WARNING
Tests with MRL-11 are capable of high voltage that can cause personal
injury or death due to electric shock. The tester should be used only by
qualified personnel who recognize the dangers of high voltage. We do
suggest that no less than two persons perform the test.
Make certain that the MRL-11 is turned off and that voltage is completely
discharged before removing the test leads. Cables can store charge if they
are disconnected from the supply while high voltage is on. The charge on
the cable can cause injury or damage even after the cable is disconnected
from the tester.
Connection to reliable earth is very important.
CAUTION
DO NOT CONNECT / DIS-CONNECT TEST LEADS WHEN
TEST IS ON THAT IS DURING TEST.
General
: Before making any insulation tests, isolate, take out of service or
dis-connect all apparatus that is the subject of the insulation test.
Capacitance discharge
: It is extremely important that when tests are made
involving capacitance and dangerously high voltage, as when making tests
on cables, transformers etc; that such circuits be discharged at the end of a
test. This must be done BEFORE THE TEST LEADS ARE
Contact Resistance Tester MRL-11
a) The instrument should be connected to a good ground.
b) The instrument’s working place should keep away from heavy electrical field, heavy
magnetic field, high frequency instruments. The less interference comes from power supply,
the better the instrument works. If the supply power’s interference is too big, you should
choose AC power purifier to supply the instrument. The capacity of the AC power purifier
should more than 200VA.
c) If the display did not show on the LCD screen, or the word’s color is too thin, you should
adjust light regulation-resistance.
d) The instrument should be stored in dry and well ventilated place. If tester is not used for
long-term or the environment is damp, before using, should lengthen to prepare hot time,
and do away with the dampness.
Attention!
