Safety warnings KEW6315
- 9 - KEW6315
DANGER
● The instrument is to be used only in its intended applications or conditions. Otherwise, safety functions
equipped with the instrument will not work, and instrument damage or serious personal injury may
occur. Verify proper operation on a known source before taking action as a result of the indication of the
instrument.
● With attention to the measurement category to which the object under test belongs, do not make
measurements on a circuit in which the electrical potential exceeds the following values.
* 300V AC for CAT. IV, 600V AC for CAT. III, 1000V AC for CAT. II
● Do not attempt to make measurement in the presence of flammable gasses. Otherwise, the use of the
instrument may cause sparking, which can lead to an explosion.
● Never attempt to use the instrument if its surface or your hand is wet.
- Measurement -
● Do not exceed the maximum allowable input of any measuring range.
● Never open the Battery compartment cover during a measurement.
- Battery -
● Do not try to replace batteries during a measurement.
● Brand and type of the batteries to be used should be harmonized.
- Power cord -
● Connect the Power cord to an outlet.
● Use only the Power cord supplied with this instrument.
- Power supply connector -
● Never touch the Power supply connector although it is insulated while the instrument is operating with
batteries.
- Voltage test leads -
● Use only the ones supplied with this instrument.
● Choose and use the test leads and caps that are suitable for the measurement category.
● When the instrument and the test lead are combined and used together, whichever lower category
either of them belongs to will be applied. Confirm that the measured voltage rating of the test lead is
not exceeded.
● Do not connect a Voltage test lead unless required for measuring the desired parameters.
● Connect Voltage test leads to the instrument first, and only then connect them to the circuit under test.
● Keep your fingers behind the barrier during a measurement.
Barrier: provides protection against electrical shock and ensuring the minimum required air and
creepage distances.
● Never disconnect the voltage test leads from the connectors of the instrument during a measurement
(while the instrument is energized).
● Do not touch two lines under test with the metal tips of the test leads.
● Never touch the metal tips of the test leads.
- Clamp sensor -
● Use only the ones dedicated for this instrument.
● Confirm that the measured current rating of the test lead and the maximum rated voltage are not
exceeded.
● Do not connect a Clamp sensor unless required for measuring the desired parameters.
● Connect sensors to the instrument first, and only then connect them to the circuit under test.
● Keep your fingers behind the barrier during a measurement.
Barrier: provides protection against electrical shock and ensuring the minimum required air and
creepage distances.
