Turning Your Instrument On And Off; Procedure - Keithley 2601B Reference Manual

Series 2600B System SourceMeter® Instrument Reference Manual
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 Series 2600B that force air (heated or unheated)
toward its cooling vents or surfaces. This additional airflow could compromise accuracy.
When rack mounting the Series 2600B, make sure there is adequate airflow around both sides to
ensure proper cooling. Adequate airflow enables air temperatures within approximately one inch of
the Series 2600B surfaces to remain within specified limits under all operating conditions.
Rack mounting high power dissipation equipment adjacent to the Series 2600B could cause
excessive heating to occur. To produce specified Series 2600B accuracies, maintain the specified
ambient temperature around the surfaces of the Series 2600B. Proper cooling practice, in rack
configurations with convection cooling only, 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
Series 2600B).
Mount precision equipment as low as possible in the rack, where temperatures are coolest. Adding
space panels above and below the Series 2600B will help provide adequate airflow.

Turning your instrument on and off

The following topics describe how to power your instrument on and off, place an instrument in
standby, and configure the line frequency.

Procedure

The Series 2600B 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 Series 2600B 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.
To turn a Series 2600B on and off:
1. Before plugging in the power cord, make sure that the front panel POWER switch is in the off (O)
position.
2. Connect the female end of the supplied power cord to the AC receptacle on the rear panel.
3. Connect the other end of the power cord to a grounded AC outlet.
