and other adverse environments.

Scientific
User Manual SME1300X 8/200
Please do not use damaged equipment. Before use of the instrument, please check if
there are any cracks on the shell.
Please connect the device with the provided cable. Before operating the instrument,
make sure the AC power supply is well grounded.
Before connecting to the device, check all the security labels on the device.
Please use wire with rated load. The capacity of all load wires must be able to withstand
the maximum short-circuit output current of the power supply without overheating. If
there are multiple loads, each pair of load wires must be able to safely carry the full
load rated short-circuit output current of the power supply.
Please do not install replacement parts or make any unauthorized modification of the
instrument.
Please do not use the device when the cover is removed or loose.
It is strictly prohibited to use this instrument on life support system or any other
equipment with safety requirements.
Keep the instrument well ventilated to avoid overheating. Do not block the ventilation
hole of the equipment to avoid internal temperature rising affecting the accuracy.
Please use dry cloth to clean the shell of the equipment. Do not clean the inside of the
instrument.
Please do not switch the instrument frequently to avoid loss of stored data.
The instrument has been carefully designed to reduce clutter due to AC power input.
However, it should still be used under low noise conditions. If that is inevitable, please
install the power filter.
When the instrument is not used for a long time, please put it in the original box or
similar box and stored in a ventilated room with temperature of 5℃~40℃and relative
humidity less than 85% RH. Do not store the instrument in a corrosive atmosphere
containing harmful impurities and should avoid direct sunlight.
