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.
If high power dissipation equipment is rack mounted next to the 2601B-PULSE, it could cause
excessive heating. To produce specified 2601B-PULSE accuracies, maintain the specified
ambient temperature around the surfaces of the 2601B-PULSE. In rack configurations with
convection cooling only, proper cooling practice places the hottest non-precision equipment
(for example, the power supply) at the top of the rack away from and above precision
equipment (such as the 2601B-PULSE).
Mount precision equipment as low as possible in the rack, where temperatures are coolest.
You can add space panels above and below the 2601B-PULSE to help provide
adequate airflow.
Turning the instrument on and off
The 2601B-PULSE operates from a line voltage of 100 V to 240 V at a frequency of 50 Hz or 60 Hz.
Line voltage is automatically sensed (there are no switches to set). Make sure the operating voltage
in your area is compatible.
Follow the procedure below to connect the 2601B-PULSE to line power and turn on the instrument.
Operating the instrument on an incorrect line voltage may cause damage to the instrument,
possibly voiding the warranty.
