What is TEDS?
"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 new 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 P1451.4, 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. In addition, it
can simplify labeling and cabling problems, as well as inventory control issues; by letting you burn location
data onto the chip when installing a sensor. 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

Introduction
The PSD Portable Strain Display Load Cell/Force transducer readout is a microprocessor based portable
instrument designed to interface with any full bridge sensor with an output sensitivity of up to 50mV/V.
Bridge resistances from 85Ω upwards can be used with the PSD.
Configuration and calibration of the PSD is achieved using the front panel push buttons to navigate through
a very simple menu structure.
User functions available on the PSD include:-
Range Selection
Display Hold/Freeze
Gross/Net indication selection
Peak Hold selection
Trough Hold selection
Shunt Cal check
The PSD is powered by two internal non-rechargeable AA alkaline batteries.

Electrical Connection Information
Sensor Connections
The standard sensor connection is a 5 pin 723 series Binder connector. The wiring for this is detailed
below:-
PIN 1 +ve Excitation
PIN 2 -ve Excitation & TEDS Common
PIN 3 +ve Signal
PIN 4 -ve Signal
PIN 5 TEDS
RS232 Port Connections
If the PSD has been ordered with the optional RS232 output, then this will be available via a 8 pin 723
series Binder connector. The wiring for this is as detailed below:-
PIN 1 Tx
PIN 2 Rx
PIN 3 Gnd
Note: PINS 4 to 8 not connected
Internal Connections
It may be necessary from time to time to know what the internal connections are. For example, if you
disturb some of the connections whilst trying to insert the range legends, or if you need to change the
internal shunt calibration resistor. These are shown below for reference only:-

There are six push buttons on the front panel of the PSD, which are available for use in normal operation.
Each of these is described below:-
Front Panel Button
Function of Button in Normal Operation Mode
To switch the PSD ON or OFF press and hold the button
The RANGE button allows the user to toggle between two independent
scales. An annunciator highlights the range that has been selected.
The HOLD button allows you to hold/freeze the current display value when
the button is pressed. Pressing the HOLD button again releases the display.
The HOLD annunciator is illuminated when in the HOLD mode, and the
display will flash, to alarm further that the user is not viewing instantaneous
display values.
The
GROSS/NET
button, when pressed, allows the user to toggle between
displaying the Gross or Net display values. This can be useful in many
applications where it is necessary to display the change in display value from
a certain part of the measurement range. When in NET mode the NET
annunciator is lit. When in GROSS mode, the NET annunciator is not lit.
The SHUNT CAL button allows the user to press this at any point in time.
The standard unit shunts a 100kΩ resistor across the negative excitation and
negative signal connections. If this is performed at the end of the calibration
procedure, then a figure can be noted, so the user can check calibration
accuracy or connection integrity. The button has to be held down to
operate. When held down the SHUNT CAL annunciator is lit and the display
will flash, to alarm further that the user is not viewing instantaneous display
values.
When the PEAK button is pressed the display will show the last Peak reading.
To reset the Peak readings press the PEAK and TROUGH buttons
simultaneously. When in PEAK mode the PEAK annunciator will be lit and
the display will flash, to alarm further that the user is not viewing
instantaneous display values. To turn off Peak mode press the
PEAK
button.
When the TROUGH button is pressed the display will show the last Trough
reading. To reset the Trough readings press the TROUGH and PEAK buttons
simultaneously. When in TROUGH mode the TROUGH annunciator will be lit
and the display will flash, to alarm further that the user is not viewing
instantaneous display values. To turn off the Trough mode press the
TROUGH
button

Menu Structure
The PSD has two menus, details of which are outlined below:-
A CONFIGURATION MENU, which enables the user to tailor the operation to meet a specific application
requirement. The values selected in the CONFIGURATION MENU are completely independent for each
range.
