The seventh, matters needing attention
1. Before using this instrument, be sure to read this operation
manual;
2. The instrument operators should be familiar with electrical
equipment or analysis instrument of general use common sense;
3. The instrument is applicable to both inside and outside the home,
but should avoid the rain, corrosive gas, high dust, high
temperatures or direct sunlight and other places;
4. The oil cup should be kept clean.During the outage, should add
enough dry qualified insulating oil immersion, keep oil cup will not
be affected with damp be affected with damp and oxide electrode;
5. Use after a month in a row, electrode should be routine
inspection and maintenance. Check and adjust the electrode gap,
make its restore standard; A magnifying glass to observe whether
the electrode surface appear dark spots, if has this phenomenon,
application of silk cloth to wipe the electrode surface, make its
restore;
6. A professional instrument maintenance and debugging should be
complete;
7. Before turning on the power supply, should check carefully
whether the cable is firm, instrument shell must be reliable
grounding.
8. After turning on the power supply, operators are strictly forbidden
to touch the oil cup lid shell, lest produce an electric shock danger!
9. The instrument is in use process, if discovery is unusual should
immediately cut off the power!

17
eighth, simple troubleshooting
1. Boot no reaction：Check whether the power cord is plugged in
properly and check whether the safety tube is intact;
2. No booster：Check whether the cap of the oil cup box is covered;
3. Normal wear without breakdown：Check if the setting limits the
boost speed;
4. No display after breakdown：Check the oil cup for dirt;
5. The printer is out of paper：Check if the printer has any paper;
6. Replace the printer paper：The printer has been installed with
printer paper. If the printing paper is used, new printing paper will
be installed. The installation method opens the printer to put the
paper bin, put the paper into the paper, extend a part. The printing
paper light faces the direction of heat - sensitive tooth.
