UNI UT219E Operating Manual on line test for resistance Diode or circuit on off 14 Do not use LoZ mode to measure the voltage in all power supplies in the circuit should be turned the circuit that may be damaged by the low off in advance discharged and all otherwise the capacitors should inaccurate be measuring result may be caused environment especially do not store the meter 6 In case the cover is removed or the cover is opened do not use the meter timely in moisture environment as the performance of moistened meter may become degraded 7 Liquid crystal display shows o symbol replace the batteries impedance 300 kQ of this mode 15 Do not use in high temperature and high humid to guarantee the measurement accuracy Type 1 5 V AAA batteries should be used for supplying power for the meter and care should 16 Do not modify the internal wiring of the meter randomly so as not to damage the meter and jeopardize the safety 17 When carrying out maintenance please use wet cloth and gentle cleanser to clean the case be taken to install the batteries correctly 8 The range switch should be set to a correct measuring position of the meter do not use lapping compound or solvent 9 It is strictly forbidden to change the position of the range switch during the measuring to prevent the meter from being damaged lO When carrying out measuring keep in mind not to extend your fingers over the hand stopping location of the probes do not touch any exposed conductor connector unused input terminal or the circuit under measuring to prevent electric shock 11 After completion of each measuring operation disconnect the probes from the tested circuit 12 Replace the probes with same grade of CATIII1000V CATIV600V or more probes 13 If the voltage to be measured is DC 30 V or AC 30 Vrms due care should be taken to avoid electric shock 3 4
