Udey MRL-11 Operating Manual
                     | |
SAFETY WARNINGTests with MRL-11 are capable of high voltage that can cause personalinjury or death due to electric shock. The tester should be used only byqualified personnel who recognize the dangers of high voltage. We dosuggest that no less than two persons perform the test.Make certain that the MRL-11 is turned off and that voltage is completelydischarged before removing the test leads. Cables can store charge if theyare disconnected from the supply while high voltage is on. The charge onthe cable can cause injury or damage even after the cable is disconnectedfrom the tester.Connection to reliable earth is very important.CAUTIONDO NOT CONNECT / DIS-CONNECT TEST LEADS WHENTEST IS ON THAT IS DURING TEST.General: Before making any insulation tests, isolate, take out of service ordis-connect all apparatus that is the subject of the insulation test.Capacitance discharge: It is extremely important that when tests are madeinvolving capacitance and dangerously high voltage, as when making testson cables, transformers etc; that such circuits be discharged at the end of atest. This must be done BEFORE THE TEST LEADS AREContact Resistance Tester MRL-11a) The instrument should be connected to a good ground.b) The instrument’s working place should keep away from heavy electrical field, heavymagnetic 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 shouldchoose AC power purifier to supply the instrument. The capacity of the AC power purifiershould more than 200VA.c) If the display did not show on the LCD screen, or the word’s color is too thin, you shouldadjust light regulation-resistance.d) The instrument should be stored in dry and well ventilated place. If tester is not used forlong-term or the environment is damp, before using, should lengthen to prepare hot time,and do away with the dampness.Attention! |
