1.4 Annual Product Calibration

1.5 Product Notes and Precautions

This product is a high-precision measurement device with
sensive components – please 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 calibraon service.

The MK350D LED Meter contains sensive 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 operang normally. Do not aempt any
repairs – all repairs must be performed by qualified service
agents.

Precauons / Warnings

Please read the following precauons to avoid fire, excessive heat, chemical
leakage and explosion.

■

Do not disassemble or modify the baery.

■

Do not expose the baery to heat (fire) or water/moisture.

■

If the unit is plugged into the power adapter and the baery seems to be
overheang, or if there is smoke or peculiar odors emanang from the unit,
unplug immediately to avoid the possibility of fire.

■

However, do not touch the cables if there is heat emanang 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, melng 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
baery to avoid fire or electric shock.

■

Do not operate or store the baery in high-temperature environments - it
will cause baery leakage and/or shorten the life of the baery .

■

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.

the packaging and connect one end of the Charger cable to
the MK350D and the other end into a wall socket with the
appropriate voltage. The indicator light will illuminate orange
indicang that it is charging. The light will turn green when
fully charged. For first me use, charge the baery for at

3.3 More about Dark Calibration

1. While your unit is charging, you can start taking measurements with the
power adaptor plugged in or you can wait unl the unit is fully charged.

2. To turn off the MK350D, press the On / Off buon and keep it depressed

3.1 MicroSD Card

3.2 Setting the Date/Time on your MK350D

This unit can write LED measurement
data onto a MicroSD Card (only
support for above 1GB / up to 32G).
Simply insert the card into the MicroSD
card slot. All data that is captured is
wrien to excel files (.xls).
Even without a MicroSD Card, the
MK350D is able to capture data .
You can read the data via Micro SD card reader and find the
data on the SD Card under the “Data”directory. There will be
subdirectories marked with a sequenal number “e.g. 0001”.
Each directory can hold up to 100 capture files, aer which
the next sequenal subdirectory will be created (e.g. 0002).

Each capture will be contained in
its own Excel file with a
namingonvenon of ESPD_XXXX,
where XXXX is a sequenal
number (e.g. 0001, 0002).
Addional data such as Integraon
Time, R1-R15, LambdaPV and all of
the intensity data for each
wavelength in the Wavelength

Spectrum are all available in the file.

By plugging your MK350D connecon to uSPECTRUM PC
soware using the USB cable supplied, the MK350D will
automacally sync up its Date / Time from the PC.
The Date / Time will also sync from a smart device if you use
the smart device to make a Bluetooth connecon to the
MK350D.

3.3 More about Dark Calibration

It is good pracce to perform a dark calibraon every me
you turn on the MK350D, when you move to a different
temperature environment (hot to cold or cold to hot), or
when you move to a different light intensity environment
(light to dark or dark to light).

You also can use PC soware or smart device APPs to do dark
calibraon.
