PC24E/25E
Page 12
The PC24E is supplied with all four channels set up and calibrated for +10V unipolar
operation. If the range is changed, the output voltages should be checked and recalibrated if
necessary using the procedure described in paragraph 2.5.8.
Jumper J3 is available on the PC25E, but would normally remain set at the default position of
10V. However, if special scaling of the PC25E for low current outputs is required, then jumper
J3 may be positioned at 2.5V.

2.5.6 Installing the PC24E or PC25E in the Computer
When the board has been correctly set up for the application as described above, it may be
installed in the host PC.
If this is the first time you have installed a peripheral card in your computer, you should refer to
the hardware manual supplied with your machine for instructions on how to remove the cover
and install devices into the input/output slot. The PC24E or PC25E may be installed in any
available slot in the machine provided that there is no restriction specified for the slot by the
manufacturer of the machine.

ENSURE THAT THE POWER TO THE COMPUTER IS
SWITCHED OFF BEFORE INSTALLING OR REMOVING ANY EXPANSION BOARD.
ALWAYS WEAR AN EARTHED WRIST STRAP AND OBSERVE PROPER PRECAUTIONS
IN HANDLING THE PC24E/25E AND ANY OTHER BOARDS BEING INSTALLED OR
REMOVED. REPAIR OF DAMAGE CAUSED BY MIS-HANDLING IS NOT COVERED
UNDER THE AMPLICON WARRANTY.
