1.3. Handling precautions
Warning
Do not directly measure the sample decomposed with nitric acid. The
activated carbon in the exhaust gas filter may generate heat. Dilute the
sample until the concentration of nitric acid falls to 5wt% or less before
the measurement.
Caution
Do not disassemble or modify the product. This may cause a
malfunction.
Use the product after consulting the manual. Improper operation
may cause malfunction or bodily injury.
Comply with the range of specifications. Failure may occur with
misuse.
Do not operate with wet hands.
Be careful when touching or handling any of the glass components or
they could be broken.
Be sure to discharge any liquid from the drain tank once the work has
been completed. It is very important to confirm that the power has
been turned OFF before starting the discharge.
If y
ou don’t turn-on MA-3000 for a long time, the sample heating tube
might be obstructed or break by moisture absorption. If you don’t
turn-on MA-3000 more than 2 weeks, please turn on the MA-3000
power switch and do conditioning, or dismount the sample heating
tube and store it in a desiccator to prevent moisture absorption.
After washing the sample boat, first dry it at about 100
C. Then, heat
at a high temperature to lower the blank. Heating a wet boat to high
temperatures can damage the sample boat.
1.4. Maintenance precautions
Warning
Maintenance of the heater must be carried out after the power has
been turned OFF and the heater has cooled down to close to normal
room temperature or it could result in burns.
Caution
Shut OFF the power supply before staring the maintenance work.
Otherwise electric shock may occur.
Be sure to do degreasing cleaning the O-ring before use. If degreasing
cleaning is not carried out, there is a possibility that the sample heating
tube will come off during measurement.
