• The instrument is a power measurement instrument that can measure
parameters such as voltage, current, and power.
Do not use this instrument for any other purpose.
• Do not use the instrument if there is a problem with its physical
appearance.
• Do not use the instrument in an atmosphere where any flammable or
explosive gas is present.
• To avoid a short-circuit or an accident to personnel, use this instrument
within the RATED circuit-to-earth voltage, maximum input voltage and
current.
• Avoid using the instrument if it has been exposed to rain or moisture or
if your hands are wet.
• Barrier is for to avoid touching the HAZARDOUS LIVE conductor.
Be careful not to across the Barrier when using the instrument.
• Do not use the instrument if there is any damage to the casing or
when the casing is removed.
• Use the test leads supplied by Yokogawa with this instrument.
• Do not use test leads that have deteriorated or are defective.
• Check the test leads continuity.
• When you attach or remove the test leads or remove the case
(for example to charge the battery), be sure to remove the test leads
from the circuit under measurement.
• When you remove the case (for example to change the battery),
be sure to remove the test leads from the instrument.
• Safety protectors such as rubber-insulated gloves should be worn to
prevent electrical shock when using the instrument.
• There are caps at the ends of the test leads. To ensure safety
(safety standard EN 61010-031), be sure to put the caps on the leads
when you use them.
• Do not open the case except when replacing batteries.
Only Yokogawa service personnel are authorized to remove the casing
or disassemble or modify the instrument.
Do not attempt to repair the instrument yourself, as doing so is
extremely dangerous.
• The product is for domestic use (Class B) and meets
the electromagnetic compatibility requirements.
• Do not use the instrument near noise-emitting equipment or where
there may be sudden changes in temperature.
Otherwise, the instrument may produce an unstable readings or errors.
• Do not wipe the instrument using an organic solvent.
When cleaning the instrument, use a dry cloth.
• Do not leave the tester exposed to direct sunlight or in a hot and humid
location such as the inside of a car, for any prolonged length of time.
• If the instrument will not be used for long periods, remove the battery.
