Chapter 8. Maintenance
8.1 Care of the instrument
Clean the instrument housing and display using a soft cloth lightly dampened with water or a mild window-cleaning product. Never use 
harsh solvents as they could cause the plastic to become brittle or damaged.
8.2 Proper Cable Handling
• Avoid twisting or knotting of the cable.
• Grasp the cable only by the connectors when connecting or disconnecting it from the instrument.
8.3 Batteries
Periodically inspect the batteries for signs of leakage or corrosion. If either occurs, remove and replace ALL the batteries. Take care to 
properly dispose of the defective batteries.
