Instrument-Computer Ground Potential Check:
Perform this check if the power cord wiring is being changed, such as for replacement of the cord or if
changing the plug.
The instrument serial port ground connection is referenced to the instrument’s internal frame and safety
ground. Before connecting the communication cable to the instrument serial port, apply power to the
instrument and the host computer. Check the ground potential (voltage) between the serial port ground
pins on the computer and the instrument. The ground connection is pin 5 on DB-9 connectors and pin 7
on DB-25 connectors. Voltages in excess of 5VAC at 110V input power, or in excess of 10VAC at
220V input power may indicate a difference in ground wiring and can damage the instrument and/or the
computer. Check the wiring and take other steps as needed to reduce this difference before connecting
the communications cable. You may also use a data optoisolator.
