SC5 Signal Conversion Analog Outputs
29
automatically adjust the signal calibration in the SC5 control software. Therefore, the position of both jumpers must
be changed for correct unipolar operation.
In order to perform this change, the following tools are required:
• 3 mm hex scredriver
• #0 Phillips screwdriver
• Small metallic tweezers with flat but roughened tips
Note: Changes between bipolar and unipolar operation require the SC5 to be opened, and the process
also requires the removal and replacement of relatively small objects close to electronic components
sensitive to electrostatic discharge (ESD). Make sure to foll
ow all directives for handling ESD
sensitive components before proceeding. A wrist strap
connected to ground must be worn when
performing the modification. Please send the SC5 back to SPECS for the modification if there is any
doubt about making the modification.
Before proceeding with the change of jumper positions, please make sure that:
• All analog inputs (2) and analog outputs (3), including the fast analog output (10) are disconnected from the
experiment.
• The SC5 is disconnected from the RC5
• The SC5 is disconnected from the mains.
Once the above conditions are fulfilled, put the SC5 on a stable and sufficiently large surface. Remove the four
plastic caps covering the screws which hold the top cover of the instrument as shown in the figure below, and
remove the screws by turning them CCW using the 3 mm hex screwdriver. Make sure not to lose the lock washers
placed below the screws. The top cover can now be carefully lifted, and should be put on the side of the instrument.
Note that there is a grounding wire connecting the top cover with the rest of the instrument, and therefore the top
cover cannot be lifted by more than 10 cm and then be removed completely.
Warning: Lethal voltages are present inside the SC5.
Note:
If a change of jumper position is required, make sure that the SC5 is disconnected from the
mains.
