8.1.1 Daily Maintenance
The maintenance described the following is necessary to make the current meter work always excellently.
Because the breakdown decreases when maintenance is done well, we will recommend maintaining it as
regularly as possible.
The following contents are general maintenance common to each equipment.
Clean the equipment.
It is cleaned only that the dust of the case, dirt, and seawater can adhere. Clean it with a
dry cloth. Especially, clean the vent with brush etc. well to improve as shown in air.
The transparency worsens when dust adheres to the display, and the image darkens. The
cleaning is wiped with a soft cloth (flannel or cotton). Do not wipe it strongly with a dry cloth.
Moreover, do not use the gasoline or thinner, etc.
Confirm loosening of parts.
Loosening of the screw, the nut, the knob, switches and connectors, and the omissions of
connectors, etc. are checked, and it tightens correctly.
Confirm the cable connecting wires.
Check the cable connecting wires between equipment and the connection such as
connectors, and confirm a certain connection.
Fuse
Exchange it after thoroughly investigating the cause when the power supply fuse cuts.
The fuse uses tubular glass type (It is included in the spare parts).
