Rules For Safe Operation

Warning

To avoid possible electric shock or personal injury,and to avoid possible damage to the Meter or to theequipment under test, adhere to the following rules:

Before using the Meter inspect the case. Donot use the Meter if it is damaged or the case(or part of the case) is removed. Look for cracksor missing plastic. Pay attention to the insulationaround the connectors.Inspect the test leads for damaged insulationor exposed metal. Replace damaged test leadswith identical model number or electricalspecifications before using the Meter.Do not apply more that the rated voltage, asmarked on the Meter.When measurement has been completed,disconnect the connection between the testleads and the circuit under test, remove the

testing leads away from the input terminals of the Meter and turn the Meter power off.Do not carry out the measurement when theMeters back case and / or battery door is openedto avoid electric shock.When the Meter working at an effective voltageover 30V in AC, special care should be taken.Use the proper terminals and function for your measurements.Do not use or store the Meter in an environmentof high temperature, humidity, explosive,inflammable and strong magnetic field. Theperformance of the Meter may deteriorate after dampened.Do not use the Meter if the surface of it is wetor the users hands are wet.When using the test leads, keep your fingersbehind the finger guards.Replace the battery as soon as the batteryindicator appears. With a low battery, theMeter might produce false readings that canlead to electric shock and personal injury.
