The following safety precautions must be observed to ensure maximum personal safety during the operation, service and repair of the SONEL CMP-2000:

1. Read these operating instructions thoroughly and completely before operating your meter. Pay particular attention to WARNINGS which will inform you of potentially dangerous procedures. The instructions in these warnings must be followed.

2. Always inspect your meter, test leads and accessories for any sign of damage or abnormality before every use. If any abnormal conditions exist (broken test leads, cracked cases, display not reading, etc.), do not attempt to take any measurements.

3. Do not expose the instrument to direct sun light, extreme temperature or moisture.

4. Never ground yourself when taking electrical measurements. Do not touch exposed metal pipes, outlets, fixtures, etc., which might be at ground potential. Keep your body isolated from ground by using dry clothing, rubber shoes, rubber mats, or any approved insulating material.

5. To avoid electric shock use CAUTION when working with voltages above 40 Vdc or 20 Vac. Such voltages pose a shock hazard.

6. Never exceed the maximum allowable input value of any function when taking a measurement. Refer to the specifications for maximum inputs.

7. Never touch exposed wiring, connections or any live circuit when attempting to take measurements.

8. Do not attempt to operate this instrument in an explosive atmosphere (i.e. in the presence of flammable gases or fumes, vapor or dust).

9. When testing for the presence of voltage, make sure the voltage function is operating properly by reading a known voltage in that function before assuming that a zero reading indicates a no-voltage condition. Always test your meter before and after taking measurements on a known live circuit.

10. Calibration and repair of any instrument should only be performed by qualified and trained service technicians.

11. Remember: Think Safety, Act Safely.

Use only the maintenance methods specified by the manufacturer. The electronic system of the meter does not require maintenance.

The casing of the meter may be cleaned with a soft, damp cloth using all-purpose detergents. Do not use any solvents or cleaning agents which might scratch the casing (powders, pastes, etc.). Dirt or moisture in the terminals can affect readings.

Clean the probe with water and dry it. Before the probe is stored for a prolonged period of time it is recommended to grease it with any machine lubricant.

The reels and test leads should be cleaned with water and detergents, and then dried.
