4.3 Reference test condition Unless otherwise specified, this specification is dependent on following condition.
5. Preparation before a measurement 5.1 Visual inspection Before starting a measurement, user should undertake visual checks on the mains cord, case and that the correct type and rated fuse is fitted to the DUT. And also there should be no evidence of damage of a nature that may impair the electrical safety of the item. 5.2 Connection to main power supply 5.2.1 Connection of mains cord Set the Function switch to VOLT Function, and connect the mains supply and the instrument with M7123 mains cord. Fig.
# WARNING • When the voltage of main power supply is 265V or more,“HI-V”is displayed on the LCD. • In that case, disconnect the mains cord of the instrument from main power supply. 5.2.3 Null setting A criteria of judgment for Earth Continuity is 1Ω, and it is low value. So even the resistance of Test Leads will affect the measurement result. This instrument, M-6201A, can cancel the resistance of Test lead by pressing Null|250V/500V switch. The procedure of Null setting is shown below.
Press Null|250V/500V switch with contacting the Test Lead and the metal parts, the resistance of Test Lead will be displayed on the LCD as shown above fig.10 for 2sec. Then, the instrument cancels the resistance value of Test Lead and adjust the displayed value to“0.00”as shown below fig.10. At this bout, NULL mark is displayed in the LCD. Null setting cannot be done when a resistance is 3Ω or more. A message“no”appears to indicate a resistance is exceeding the Null setting range.
6. Measuring method 6.1 Class I Test The purpose of the test carried out for Class I appliances is to check the insulation resistance between accessible conductive parts and connection of protective earth and between live wire parts and accessible conductive parts is within the range defined in the standards. To conduct the tests of protective conductor resistance and insulation resistance for DUT, connect the mains plug of DUT to the test socket (1) described in clause 3.4.
Class I Test Flowchart Start ⑴. Protective conductor resistance. No RPE < = 1Ω? Light up in red “no”→ “Con” →“value”will be repeated on the LCD.
