Page 6: Mount The Instrument
Mount the Instrument The Keithley 6487 should be installed using one of the provided rack mount kits. The half rack mount kit contains mounting ears, panel, handles (optional), and screws that adapt the front panel to fit into an 88.9 mm (3.5 in) tall full rack space. Refer to Figure 4 for installation details. The dual half rack mount kit contains inner and outer mounting ears, handles (optional), and screws that adapt the front panel to fit into an 88.9 mm (3.5 in) tall full rack space beside an existing instrument. - Page 7 Connect the Interlock Adapter Cable (Models 8404/8407 only, prior to 02//14/2014) 1. Lake Shore has discovered that some of the connection cables to the interlock connector on the Keithley 6487 Picoammeter Voltage Source were made incorrectly. The pins outs were not in the right location, but Lake Shore has solved this problem by making an adapter cable with the correct pin outs.
