16-bit CRC register, and put the result in the
CRC register;
3. Shift the content of the register to the right by
one bit (towards the lower bit), fill the highest
bit with 0, and check the lowest bit;
4. If the lowest bit is 0: repeat step 3 (shift again)
If the lowest bit is 1: XOR the CRC register
with the polynomial A001 (1010 0000 0000
0001);
5. Repeat steps 3 and 4 until the right shift is 8
times,so that the entire 8-bit data has been
processed;
6. Repeat steps 2 to 5 to process the next 8-bit
data;
7. The final CRC register is the CRC code;
8. When putting the CRC result into the
information frame, exchange the high and low
bits, with the low bits first.
Electrical Connection Precautions
In order to ensure safety, the electrical
connection should be done by professionals.
Because static electricity can damage the
internal electronic components of the instrument,
the performance of the instrument will be
reduced or damaged. The manufacturer
recommends the following measures to prevent
the instrument from being damaged by static
electricity:
Discharge static electricity from your body
before touching any of the meter's electronic
parts, such as printed circuit boards and the
components on them. This can be done by
touching a grounded metal surface of an
instrument case, or a metal conduit or pipe;
To reduce static buildup, avoid excessive
movement. Ship static-sensitive components in
an antistatic container or packaging;
To discharge static electricity from the user's
body and keep static electricity dischargeable,
wear a wrist static arrestor connected to a
3D calibration has been done
before leaving the factory,
and users do not need to
calibrate. In special cases, it
can be carried out according
to the maintenance schedule
required by the competent
authority.
Clean the sensor
Clean the outer surface of the sensor with water.
If debris remains, wipe it with a damp soft cloth
or gently brush it with a soft brush.
Do not place the sensor where it will be exposed
to direct sunlight or through reflection.
After-sales service
The device has no moving parts and does
not require complex routine maintenance on
site.
If the user opens the device by himself or
damages the safety seal on it, he will no
longer enjoy our quality assurance and
guarantee.
If there is any problem with the equipment,
you can contact the company's staff to
analyze and answer the problem;
