therefore only connect an external signal to the Tach / FCN BNC once the FFT function has been
selected
.
It should be noted that the maximum input capability of the FFT input is
5V pk
. See
section4.7for further details on the operation.
3.5.2.
Configuration
Within the configuration menu, further menus are selectable; refer to Figure 2for details.
3.5.2.1.
Clock
The simulator has a real time clock installed primarily to record the date when a
calibration is performed. It has a 24 hour time format and an ISO 8601 date format of
yyyy:mm:dd. See section 4.8for details on setting the time and date.
3.5.2.2.
Backlight menu
To optimize battery life the backlight can be set for ON (timed) or permanently OFF. In
the ON mode, the backlight will remain on for approximately 30 seconds from the last
key press, after which it will extinguish. A subsequent key press will turn the backlight
on for a further 30 seconds. In the FFT mode, the backlight will remain on, if selected, i.e.
the 30 second timer is disabled in this mode. See section 4.9for further details.
3.5.2.3.
Calibration
The calibration mode allows for the simulator to be calibrated without the need for
removing covers or calibration seals. A unique password, supplied with the simulator at
the time of delivery, is needed to gain access to the calibration process. For security, and
to avoid inadvertent calibration, the password should remain with authorized personnel.
See section 5.1for the calibration procedure.
3.5.2.4.
Firmware upgrade
Should it be necessary to upgrade the firmware at any stage, the process will be
initiatedwithin this routine. Full details on how to install the upgrade will be providedat
the time a firmware upgrade is needed.
3.5.2.5.
Clear all profiles
Selecting this menu option allows for the quick removal of all stored user profiles. The
user has to confirm the action before initiating.
3.5.2.6.
Change contrast
Select this menu option for adjusting the display contrast. See section 4.10for details.
3.5.3.
Output socket select
The mV/IEPE output is configured to simulate either a single ended millivolt source or an IEPE
biased millivolt source. It is important that before making any connections to the simulator, it is
correctly configured for the application, i.e. select mV or IEPE as appropriate. The current setting
is shown in the top left corner of the home screens. Note: This is a global setting. See section
4.11for details.
3.5.4.
Download data
Selecting this menu option prepares the simulator for communication with a PC allowing the
download of user profiles into the simulator and the synchronization of the real time clock.
3.5.5.
About
Select to see information on the date of manufacture (D.o.M), the serial number of the simulator,
firmware revision and the date of the last calibration.
