conforms to the safety requirements for CAT III 600 V, and the voltage measurement part conforms to the safety requirements for CAT II 600 V, CAT III 300 V measuring instruments. Service entrance Distribution panel Service drop Internal wiring Power meter Fixed Installation Outlet CAT IV CAT III CAT II DANGER Measuring a location with a higher category number than the measurement category indicated on this device may result in a serious accident such as electric shock. To avoid electric shock, do not touch the portion beyond the protective barrier during use. Never apply voltage to the test leads when the resistance and continuity functions are selected. Doing so may damage the instrument and result in bodily injury. To avoid electrical accidents, remove power from the circuit before measuring.

and damage to the instrument, disconnect the test leads from the measurement object before switching the rotary switch. • To prevent electric shock, when measuring the voltage of a power line use a test lead that satisfies the following criteria: • Conforms to safety standards IEC61010 or EN61010 • Of measurement category III or IV • Its rated voltage is higher than the voltage to be measured • The optional test leads for this instrument conform to the safety standard EN61010. Use a test lead in accordance with its defined measurement category and rated voltage.

inappropriate locations may cause a malfunction of instrument or may give rise to an accident. Avoid the following locations: • Exposed to direct sunlight or high temperature • Exposed to corrosive or combustible gases • Exposed to a strong electromagnetic field or electrostatic charge • Near induction heating systems (such as high-frequency induction heating systems and IH cooking equipment) • Susceptible to vibration • Exposed to water, oil, chemicals, or solvents • Exposed to high humidity or condensation • Exposed to high quantities of dust particles

check that the insulation on the test lead and flexible sensor (optional) are neither ripped nor torn, and no metal conductor inside the wire are exposed before using the instrument. If damaged, replace them with those specified by our company. • To prevent a short circuit accident, be sure to use the test leads with the sleeves attached when performing measurements in the CAT III measurement category. • If the sleeves are inadvertently removed during measurement, stop the measurement. • With regard to the electricity supply, there are risks of electric shock, heat generation, fire, and arc flash due to short circuits. If persons unfamiliar with electricity measuring instrument are to use the instrument, another person familiar with such instruments must supervise operations. • This instrument is measured on a live line. To prevent electric shock, use appropriate protective insulation and adhere to applicable laws and regulations. • Handle and dispose of batteries in accordance with local regulations.

jaw tips (or flexible loop couplings) or insert foreign objects into the gaps of the jaws (or flexible loop couplings). Doing so may worsen the performances of the sensor or interfere with clamping action. Poor performance or damage from battery leakage could result. Observe the cautions listed below: • Do not use batteries after their recommended expiry date. • Do not allow weak batteries to remain in the instrument. • Replace batteries only with the specified type. • Remove the batteries from the instrument if it is to be stored for a long time. • The indicator lights up when the remaining battery capacity is low. In this case, the instrument's reliability is not guaranteed. Replace the battery immediately. • To avoid battery depletion, turn the rotary switch OFF after use (the auto power save feature consumes a small amount of current).

Inspection Before Measurement • Verify that the instrument operates normally to ensure that no damage occurred during storage or shipping. If you find any damage, contact your authorized Hioki distributor or reseller. • If damage is suspected, check the section below before contacting your authorized Hioki distributor or reseller. 1 Check that the test lead is not broken. Replace with the specified L9208 Test Lead. 2 Check that the resistance measurement and continuity test operates normally. Have the instrument repaired by the your authorized Hioki distributor or reseller. The instrument may have been subject to a voltage of greater than 600 V during resistance measurement or continuity testing. 3 Check that the battery voltage is not low. Replace the batteries.
