Temperature And Ventilation; Defects And Abnormal Stresses - Gamry Instruments eQCM 15M Operator's Manual

Sources of earth ground include:
Most metal water pipes,

the chassis of most electronic apparatus (which are generally earth-grounded), and

the protective ground terminal of an AC mains power plug.

We recommend that you discuss grounding with an electrical or electronics professional prior to making
this earth-ground connection.
Note that this connection of the instrument to an earth ground is not a "Protective Earth Ground" as defined in
EN 61010.
This binding post is not intended for any use other than connecting the eQCM 15M to an earth ground to
improve shielding against noise. Connecting this binding post to a hazardous voltage can create a significant
safety hazard.
Warning:
ground. An improper connection can create a safety hazard, which could result in personal injury or death.

Temperature and Ventilation

Your eQCM 15M Electrochemical Quartz Crystal Microbalance was designed for indoor use at ambient
temperatures between 0°C and 45°C.
Caution:
should suffer no damage due to excessive heat, the enclosure may become uncomfortably hot to the touch
with insufficient air flow around the chassis.
Be careful when operating the instrument in an enclosed space (such as an enclosed relay rack or NEMA
enclosure). The temperature within the enclosure must not exceed 45C. You may need to provide ventilation
holes or even forced air-cooling for the enclosed space if excessive temperature rise occurs.

Defects and Abnormal Stresses

Treat your eQCM 15M as potentially hazardous if any of the following is true of the unit:
It shows visible damage,

It does not operate properly,

It has been stored for a long period of time under unfavorable conditions,

It has been dropped or subjected to severe transport stress,

It has been subjected to environmental stress (corrosive atmosphere, fire, etc.).

Safety Considerations
Do not connect the chassis-ground binding post to any voltage other than earth
Do not block the airflow around the instrument chassis. While the circuitry
