# CAUTION • When using Test Leads with alligator clip, be sure to check the alligator clip is firmly connected to the metal part of the device under test. Otherwise, inaccurate measurement or arc at the contacts may occurs. • The rated measuring voltage for insulation test is 500V.DC. For electrical devices to be tested, if this test voltage seems not proper to apply, contact your distributor and ask for advices. -

Page 13: Preparation Before A Measurement
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. -
Page 14: Null Setting (Protective Conductor Resistance Function)
# 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. -
