Introduction / Overview
The 9325-NU (Portable Sensor Display Standard) for strain bridge sensors is a microprocessor based portable
display instrument designed to interface with any full bridge sensor with an output sensitivity of up to 480mV/V.
Bridge resistances from 85 ohms upwards can be used with the 9325-NU.
This module can be either used as a handheld device or, using the optional mounting accessories, or attached to
equipment, dashboards, walls, or desks.
Configuration and calibration of the 9325-NU is achieved by using the front panel keypad menu system.
User functions available on the 9325-NU include:
• Range Selection
• Gross/Net indication selection
• Min/Max
• Units
• TEDS support
The 9325-NU is powered by two internal non-rechargeable AA alkaline batteries.
Key Concepts
Calibration Ranges
There are six calibration ranges available that can be individually calibrated for use with strain bridges that do not
have TEDS capability.
These ranges can be used for connecting to different strain bridges or for different sections of the same strain
bridge i.e., one for compression and one for tension. The ranges are user selectable and independent of what is
physically connected to the handheld.
The number of ranges available and the ability to switch between these ranges can all be controlled when
configuring the handheld.
Each of these ranges will remember settings that contribute to the user experience so for settings such as
selected units and tare values etc. these will be remembered and reused as each range is selected again.
Note: The 9320-NU only allows for calibrations with a live load. If mV/V entry calibration is needed, please
contact Interface Inc, and we will provide you with a method to achieve this.
In addition, there is also support for TEDS calibration tables in TEDS capable connected devices where the
calibration information is held in the connected sensor. The user experience settings will be remembered for the
last twenty connected TEDS sensors. There is an option to disable TEDS support on a particular TEDS enabled
sensor so the handheld calibration ranges can then be used instead.

Decimal Point Position and Resolution
Because the 9325-NU can handle so many engineering units out of the box and allow conversion between
suitable units the way it handles decimal point positions and resolution (For displays) needed a complete
overhaul compared to the original 9320.
On the original having only two calibration ranges (And no concept of engineering unit conversion), each range
had its own formatting settings for decimal points and resolution and these ranges were very often used to
deliver results from the same strain bridge sensor in two different engineering units.
The new 9325-NU has six calibration ranges available where each can automatically convert between the
calibrated units and any other unit the user wants to display the values in. Therefore, because each calibration
range can display a whole range of engineering units (Although this can be limited by the user it still has that
capability) setting the decimal position and resolution per range does not work anymore. I.e. changing from
grams to tons would be nonsensical if they both shared the setting for 1 decimal place for example. This is even
worse for resolution settings when switching between kg and lbf as the display would no longer count in
increments suitable for both units.
So, the 9325-NU now supports settings for both decimal point position on a per unit basis and resolution on a per
calibration range basis.
Out of the box the decimal point position for all units has a sensible default but these can easily be changed
using the keypad (until the user chooses to disable that feature) by long presses on the left and right keys. When
you are viewing a particular unit simply adjust with the keys and this setting will be remembered any time that
unit is selected in any calibration range, or a TEDs device is connected showing that unit. Decimal places can be
set from zero to seven. The resolution is disabled by default and is unwieldy to allow changing via the keypad or
menu system.
Resolution is stored against each Calibration Range (Or in the case of a TEDS device, per device) and is set in the
base calibrated units for that range at the factory. For the chosen display units resolution snaps to the nearest
appropriate 1,2 or 5 multiple in that unit. i.e.( .0001, .001, .01, .1, 1, 10, 100, .0002, .002, .02, .2, 2, 20, 200, .0005,
.005, .05, .5, 5, 50, 500.)
This selection works across all display modes.
TEDS (Transducer Electronic Data Sheet)
"Plug and play sensor hardware and software make configuring a smart TEDS sensor as easy as plugging a mouse
into a PC. The technology has greatly improved efficiency and productivity by completely eliminating manual
sensor configuration."
Basic concept
TEDS is at the heart of the universally accepted IEEE 1451.4 standard for delivering Plug and Play capabilities to
analogue measurement and test instruments. In essence, information in a Transducer Electronic Data Sheet
provides interfacing devices with the critical sensor calibration information in order to perform accurate and
precise measurements every time.
TEDS works in a similar way in which USB computer peripherals immediately work as they are connected. TEDS
enabled equipment maybe swapped and changed without recalibration, saving time and money.
TEDS holds information such as a sensor manufacturer, model and serial numbers, and more importantly all the
calibration settings determined by the manufacturer.

How it works
Plug and play is a data acquisition technology that can simplify the configuration of automated measuring
systems by making a sensor’s unique identification data available electronically. As implemented according to
IEEE 1451.4, data in the form of a transducer electronic data sheet (TEDS) is burned on an electrically erasable
programmable read-only memory (EEPROM) chip located on the sensor, so when a properly adapted signal
conditioner interrogates the sensor, it can interpret the self-identification data. This technology provides a great
benefit by eliminating the need for paper calibration sheets. And because all sensors produced according to the
standard will carry the same basic identically formatted self-identification information, you will be able to mix and
match sensors and applicable signal conditioners across manufacturers.
Advantages
Plug and play sensors are revolutionizing measurement and automation. With Transducer Electronic Data Sheets
(TEDS), your data acquisition system can detect and automatically configure sensors. This technology provides:
• Reduced configuration time by eliminating manual data entry
• Better sensor tracking by storing data sheets electronically
• Improved accuracy by providing detailed calibration information
• Simplified asset management by eliminating paper data sheets
• Reliable sensor location by identifying individual sensors electronically

9325-NU Specifics
All standard TEDS devices contain a basic 2-point calibration. TEDS devices can also optionally hold more than
one extended calibration table; template ID=40 (multi-point calibration) or template ID=41 (polynomial
calibration). When you first connect a new TEDS device to the 9325-NU a message will be displayed stating that a
new TEDS device has been detected and that default settings have been used.
The first detected, valid calibration table from the TEDS device will be selected.
The user can select an alternative calibration table from the menu or Toolkit and this selection will be
remembered and the table will be re-selected next time the device is plugged in.
The 9325-NU will remember the last twenty connected TEDS devices so will automatically select the most
recently used calibration table and will re-use the User Experience parameters such as Units and tare values.
There is also an option to ignore TEDS on specific devices so that the 9325-NU Calibration Ranges can be used
instead of any Calibration Tables held in the connected TEDS device.
In this case the User Experience parameters will be used from the selected Calibration Range. i.e. The device will
act as if there is no TEDS chip until the user re-enables TEDS for this device. When a TEDS disabled device is
connected again it will automatically switch to the last used 9325-NU Calibration Range.
Supported TEDs Hardware Devices
DS2431 and compatible devices
DS2433 and compatible devices
DS28EC20 and compatible devices
Extended TEDS Calibration Options
The 9325-NU supports up to five extended TEDS calibration tables in addition to the standard 2-point
calibration. These can be any combination of template ID=40 (multi-point calibration) or template ID=41
(polynomial calibration). This could be used to provide multiple calibrations for the transducer, for example high
range, low range, tension & compression.
Typically, a TEDS-enabled transducer would be supplied with one additional calibration template. The default
behavior is to select the first calibration template, or the standard 2-point if a calibration template is not found.
The user can cycle between all the available calibrations unless this feature has been restricted.
The TEDS standard allows very large or complex calibration templates to be defined. For practical reasons the
9325-NU imposes restrictions on the size and complexity that is allowed.
Multi-Point Calibration (template ID=40)
• Maximum calibration points = 10
Polynomial Calibration (template ID=41)
• Maximum number of segments = 1
• Maximum number of coefficients = 10 (10th order polynomial)
A 4 Kbit (or larger) device is recommended where additional TEDS calibration templates are
to be included.

User Operation
Keypad
The keypad has some functionality that is fixed and some that can be configured and some that changes
depending on what is on the LCD display. The handheld can optionally sound a beep when keys are pressed.
Key
Function
The top right key doubles as the power key. Hold this for
approximately two seconds to turn on or off the handheld.
The three keys along the top of the keypad are soft keys and relate
to the three descriptions shown directly above them on the LCD
display. The action of these keys will depend on what is currently
being viewed.
The navigation keys are used for various purposes such as selecting
the current calibration range, selecting the current display,
navigating the menu system or editing string and numeric values.
The OK key is used to open the menu (If that has been allowed in
the configuration) and to select menu items and complete editing
sessions.
Later we will explain how to use the keys to navigate the menu
system.
When not in a menu the Up/Down keys can perform one of a few
user definable functions but the default is to cycle through all
available calibration ranges.
If a TEDS device is attached then these keys will cycle through any
valid Calibration Tables held in the device. If There is no TEDS device
(or manual override for that particular TEDS device has been set)
then the keys will cycle through the internal device Calibration
Ranges.
In both the menu and the toolkit the user may also select an action
for a long press. A long press is where the key is held down for over
a second before being released.

The set of icons displayed along the top left of the display are common to all display modes and have the
following meanings.
A warning is detected. Further investigation of
the warning may be required either via the
keypad or software.
Also displayed when alarm is triggered.
External USB power has been applied.
Battery is low.
The keypad has been locked because some
critical processes are being performed by the
Toolkit or other software.
The Scale Steady functionality is active but
the reading is not steady.
The measurement system is operating in 4-
wire mode instead of 6-wire mode. (This
feature is only available in certain versions and
is not available to change by the user.)
A TEDs device is detected as being
connected.
The main display is showing the Net value
because a Tare has been executed.
The TEDs device is using an internal
calibration range rather that its own
calibration table.
The temperature is now too low to operate the
LCD at its normal update rate. A slower update
rate has been applied. Note that internal
measurement (such as peak detection) will not
be affected.

Menu Basics
The menu is accessed by holding the OK key for around one second. It is possible to lock out the menu system so
if your handheld does not display a menu it may be that your supplier has locked this feature.
Individual features may also have been hidden by your supplier.
The currently selected menu item is displayed on a dark background and this selection can be changed by using
the up and down keys. Pressing OK will select that item and can either:
• Perform an action (Such as increasing LCD contrast)
• Edit a value (Such as editing an alarm level value)
• Display the items sub menu (Indicated by a following > symbol)
The menu system is a standard hierarchal one but does have some visual clues to help you navigate.
• If a menu item leads to a sub menu (Another list of items) it will display a ►to the right.
• If a menu item is part of a list where only one item can be selected at a time then the current active
selection is indicated by a leading dot ●to the left. All items that this can apply to are shown as a ●
below for clarity.
• Some items will lead to a displayed value or text which may be edited. See the next section regarding
Editing Values where this is described. Shown as a following ●●● for clarity.
