SafetyPrecautions

1. Improperuseofthismetercancausedamage,shock,injuryordeath.Readandunderstandthis

usermanualbeforeoperatingthemeter.

2. Makesureanycoversorbatterydoorsareproperlyclosedandured.

3. Alwaysremovethetestleadsbeforereplacingthebatteryorfuses.

4. Inspecttheconditionofthetestleadsandthemeteritselfforanydamagebeforeoperatingthe

meter.Repairanydamagebeforeuse.

5. Donotexceedthemaximumratedinputlimits.

6. Usegreatcarewhenmakingmeasurementsifthevoltagesaregreaterthan25VACrmsor

35VDC.Thesevoltagesareconsideredashockhazard.

7. Alwaysdischargecapacitorsandremovepowerfromthedeviceundertestbeforeperforming

Diode,ResistanceorContinuitytests.

8. Removethebatteryfromthemeterifthemeteristobestoredforlongperiods.

9. Toavoidelectricshock,donotmeasureACcurrentofanykind
