1.4 Annual Product Calibration
This product is a high-precision measurement device with sensitive components –
handle with care. To ensure the accuracy of measurements, it is recommended to have
the unit calibrated once a year. Please contact your agent or our customer service
department for calibration service.
- 6 -
1.5 Product Notes and Precautions
The MK350S LED Meter contains sensitive components. Please unpack with care,
as any trauma to the unit may damage the equipment. Contact your agent if the unit
appears not to be operating normally. Do not attempt any repairs – all repairs must
be performed by qualified service agents.
Most LCD screens have a very small and inconsequential defective pixel rate
(usually less than 0.1%). This results in occasional pinpoints of white or other colors
but will not affect the accuracy of measurements.
1.
2.
Please read the following precautions to avoid fire, excessive heat, chemical leakage
and explosion.
Precauons / Warnings
Do not disassemble or modify the battery.
Do not expose the battery to heat (fire) or water/moisture.
When disposing used/old batteries, wrap with insulation tape to shield the battery
from electrical contact with metallic objects, which might ignite a fire or explosion.
If the unit is plugged into the power adapter and the battery seems to be
overheating, or if there is smoke or peculiar odors emanating from the unit, unplug
immediately to avoid the possibility of fire.
However, do not touch the cables if there is heat emanating from near the cables
as melted or deformed cables could expose wiring and result in burns or electric
shock.
Do not use cloth or anything to wrap or cover the equipment while charging – this
could cause the unit to overheat, melting the casing or causing fire.
If the unit is accidently immersed in water, or if moisture has seeped inside, or
metal objects have dropped into the casing, immediately remove the battery to
avoid fire or electric shock.
Do not operate or store the battery in high-temperature environments - it will cause
battery leakage and/or shorten the life of the battery .
Do not use paint thinner, benzene or other organic solvents to clean the equipment
– this may damage the exterior finish or touch screen, and may even ignite fire.
