Chapter Eight: Maintenance and Troubleshooting

General Information

Periodically check for wear on the cables and inspect the enclosure for visible signs of damage.
The only maintenance required on the 670 instrument is to change the fuses.

How To Clean the Unit

Periodically wipe down the unit with a damp cloth. Do not use any solvents to clean the unit.
