LAPTOP COMPUTER
The laptop computer is connected to the Data Acquisition Unit via the USB Extender
Sender and RJ-45 cable. The laptop computer provides a means of displaying the rectifier
data. It also allows access to the internal test signal generator. The data is displayed on a
spreadsheet program.

FLEXIBLE CURRENT SENSORS
The 3.625 ID Flexible Current Sensor is the standard sensor supplied with the RCEM.
Other Flexible Current Sensor sizes are available from DynAmp, if required. Presently they
include inside diameter (I.D.) sizes of 1.000", 1.500", 2.750", 4.250", and 2.875” x 5.500”
models. All Flexible Current Sensors have the same output, so they may be interchanged.

MAGNETIC FIELD STATEMENT
The magnetic field from a high current DC bus may damage or destroy the laptop
computer hard disk drive, or floppy disks. To avoid damage
the laptop and floppy disks
should be kept as far from the DC bus as practicable.
Protect floppy disks in a
magnetic shielded case. This warning applies at all times.
The destructive effect of a magnetic field on a hard disk drive depends on the orientation of
the laptop computer within the field, and the degree of magnetic shielding provided by the
hard disk enclosure. Laptop computer and hard disk manufacturers do not provide
specifications for maximum magnetic field outside the hard disk enclosure.
It is difficult to accurately specify a maximum safe Gauss level for laptop computer disk
drives. Our best estimate is a maximum ambient magnetic field strength of 25 to 50 Gauss
for safe laptop computer operation.
This manual provides recommended guidelines for use of the rectifier monitoring system.
It is the sole responsibility of the customer to assure safety of equipment and personnel
when using this product.
