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 issue; 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 IHH200 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 85: upwards can be used with the IHH200.
Configuration and calibration of the IHH200 is achieved using the front panel push buttons to navigate through a very simple menu structure.
User functions available on the IHH200 include:-
Range Selection Display Hold/Freeze Gross/Tared indication selection Peak Hold selection Valley Hold selection Shunt Cal check
The IHH200 is powered by two internal non-rechargeable AA alkaline batteries. There is an option to have rechargeable 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 Connections
If the IHH200 has been ordered with the optional RS232 output, then this will be available via a 7 pin 723 series Binder connector. The wiring for this is as detailed below:
PIN 1! Tx PIN 2! Rx PIN 3 ! Gnd
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:

Front Panel Button
Function of Button In Normal Mode
To switch the IHH200 ON or OFF press and hold the VALLEY 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/TARED button, when pressed, allows the user to toggle between displaying
the Gross or Tared 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 TARED mode the TARED annunciator is lit. When in GROSS mode, the
TARED 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 VALLEY 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 VALLEY button is pressed the display will show the last Valley reading. To reset
the Valley readings press the VALLEY and PEAK buttons simultaneously. When in VALLEY
mode the VALLEY 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 Valley mode press the
VALLEY button.
