request is displayed, so press the key under "Yes" to confirm the request and perform the
RAM Dump.
It is important to note that ALL
user defined test set-ups and TEST DATA will be
erased by this procedure so the customer should be informed and asked to save
any data BEFORE

requested when the RIGHT HAND key is pressed.
b Hand Held Remote
To perform a RAM Dump, switch the machine on then press the ► key repeatedly.
The normal start up screen will show "Lloyd Instruments", then the display will show
load and extension values then "Lloyd Instruments" will be displayed again for a short
time period to confirm that the RAM Dump was performed.
Note that if the RAM is REPLACED for any reason, its internal time clock MUST be set to the
correct time by connecting the machine to a computer then starting the NEXYGEN Plus 3
Software Console. When this console communicates with the machine, the clock in the RAM
will be set to the current time of the host computer.
1.6 Changing a Loadcell
The machine is fitted with an S Type YLC (or XLC) loadcell and this is fitted underneath the
moving crosshead using a vertical bolt. The loadcell may be easily interchanged by one of a
different value by disconnecting the plug and unscrewing the mounting bolt. Note that the size of
the thread on the bolt depends upon the loadcell value.
1.7 Computer Control
The machine is fitted with an integral USB interface and is connected to the PC using the
supplied USB cable, part number CBT/1357/00. Note that an FTDI USB driver is required on
the PC before the machine can be connected and this is available on the NEXYGEN Plus 3 CD
or can be downloaded from the FTDI website at http://www.ftdichip.com/FTDrivers.htm
The machine can be fully controlled using the Lloyd Instruments NEXYGEN Plus 3 Software
program, which can be used with either Windows XP or Windows 7. The software controls
the machine, displays a graph during a test and automatically calculates the required test
results at the end of a test. The USB connection allows the machine to be controlled by any
computer, even if the PC is not fitted with a serial (RS232) connector.
Note that if a Hand Held Remote is supplied, then the machine can ONLY perform tests
using the NEXYGEN Plus 3 software.
