Cooling vents
The 2601B-PULSE has side and top intake and rear exhaust vents. One side must be unobstructed
to dissipate heat.
Excessive heat could damage the 2601B-PULSE and degrade its performance. Only operate the
2601B-PULSE in an environment where the ambient temperature does not exceed 50 °C.
Do not place a container of liquid (water or coffee, for instance) on the top cover. If it spills, the liquid
may enter the case through the vents and cause severe damage.
To prevent damaging heat build-up and ensure specified performance, use the
following guidelines.
The rear exhaust vent and either the top or both side intake vents must be unobstructed to
properly dissipate heat. Even partial blockage could impair proper cooling.
Do not position any devices adjacent to the 2601B-PULSE that force air (heated or unheated)
toward its cooling vents or surfaces. This additional airflow could compromise accuracy.
When rack mounting the 2601B-PULSE, make sure there is adequate airflow around both
sides to ensure proper cooling. Adequate airflow enables air temperatures within
approximately one inch of the 2601B-PULSE surfaces to remain within specified limits under
all operating conditions.
