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, (template 33), 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

Operation Features
Normal Display Operation
The IPM25 has a full 7 digit display, which can be scaled using the calibration menu to suit the application it is to be
used in. The display can display the instantaneous, peak or trough values. It is also possible to hold the display value
(this only operates when not in peak or trough mode).
The display update rate, decimal point position and resolution can be set to suit.
The IPM25 has two independent ranges. All values set in one range are totally independent from the other.
Switching the IPM25 On/Off
The IPM25 is switched ON or OFF by pressing and holding down the button for 3 seconds.
It is also possible to set an Auto-off value in the configuration menu, so that the IPM25 automatically switches itself off
after a preset time, if there is no keyboard activity.
RANGE Button
The range feature allows for the setting of two totally independent setup ranges to be selected, if required. To switch
between ranges simply press the range button. If TEDS has been enabled then only 1 range is permissible.
When you enter either the calibration menu or configuration menu, the parameters you will be setting are those for the
range you have selected. An LED is lit to identify which range has been selected.
The IPM25 is supplied with engineering unit legends; these can be slid into a window, located on the inside of the front
panel. These labels then help to further identify the units being displayed for each range. Please refer to the photo
below:-
Legend labels are
inserted both sides

HOLD Button
The hold button allows the user to freeze the display when it is pressed. When pressed again the display returns to it’s
normal operating mode. When in hold mode the display will flash and the hold LED will be lit, to ensure that this
feature is not accidentally turned on without the user noticing.
The hold feature can not be used when the IPM25 is in either peak or trough hold mode.
GROSS/NET Button
The gross/net button, when pressed, toggles between the gross and net display values. This enables the user to zero
the display (by putting the IPM25 into net mode) and displaying the change in display value from that point.
This is useful for certain weighing applications where a tare weight exists, which can be removed by putting the IPM25
into net mode.
SHUNT CAL Button
The shunt calibration button, when pressed, puts an internal 100kresistor across the –ve excitation and –ve signal
of the sensor, generating a simulated output from the sensor, therefore giving a simulated display value. This can be
pressed immediately after the sensor has been calibrated with the IPM25 and noted down for later reference. The
value noted can be used to get an idea of the calibration accuracy at a later date, or for checking the integrity of the
sensor and sensor cabling.
The shunt calibration resistor can be changed to suit specific requirements. It is suggested that a 15ppm ±0.1%
tolerance resistor is used.
PEAK Button
When pressed this button puts the IPM25 into peak mode. This will display the highest display reading and hold it on
the display until it is reset or a higher value is reached. To reset the peak display, press the peak and trough buttons
simultaneously. In peak mode it is possible to capture peaks at a rate of up to 25Hz. To turn off the peak mode, press
the peak button.
TROUGH Button
When pressed this button puts the IPM25 into trough mode. This will display the lowest display reading and hold it on
the display until it is reset or a lower value is reached. To reset the trough display, press the peak and trough buttons
simultaneously. In trough mode it is possible to capture troughs at a rate of up to 25Hz. To turn off the trough mode,
press the peak button.

Configuration Menu Parameters
SEt ZEro Parameter
The SEt ZEro parameter is meant to be accessible to the user. It allows the removal of fixed display offset values from
the display, so that the GROSS and NET features can operate from a zero point. This may also be considered as a
manual tare facility. To zero the display, simply enter the value that you wish to subtract from the display in the SEt
Zero parameter. i.e. if the display reads 000.103 and you wish it to read 000.000, then enter 000.103 in the SEt ZEro
parameter.
Set Zero may also be achieve by pressing Gross/Net and Shunt Cal button simultaneously.
Different values can be set for each RANGE.
SEt rAtE Parameter
The SEt rAtE value sets the display update rate. The options available are 25Hz, 10Hz, 3Hz, 1Hz and 0.5Hz. Different
updates rates can be set for each RANGE.
The 25Hz rate only updates at this rate when in the PEAK or TROUGH mode. When in normal display mode it has
been limited to a 3Hz update, as the digit fluctuations are impossible to view with the human eye.
The 10Hz, 3Hz, 1Hz and 0.5Hz rates update the display every 100mS, 300mS, 1000mS and 2000mS respectively.
The IPM25 when it leaves the factory is set at 3Hz.
SEt OVEr Parameter
The SEt OVEr parameter allows the user to set a visual alarm. The value that is entered is the display value that you
want the alarm to activate at. When the alarm is activated the word OVErLOad appears on the screen. To remove the
alarm, the display value must be reduced to a value that is lower than that set in the SEt OVEr parameter. This can be
very useful as a safety feature, or simply as a quick indication of when a preset level has been reached.
This value entered can be anywhere over the entire display range, so there are no limitations. Different values and
settings are available for each RANGE.
SEt OPEr Parameter
The IPM25 has a special power saving mode, which can be enabled or disabled within this parameter, pressing
when asked whether you wish to select P SAvE? will put the IPM25 into power save mode for the RANGE selected.
Pressing will de-activate the power save facility.
When the power save facility is activated, battery life is conserved by pulsing on the excitation voltage to the sensor.
As a result the accuracy is reduced, as is the update rate. When in this mode, the quickest update rate is 3Hz and the
accuracy of the display is reduced to 1 digit in 10,000. It is important to note these limitations when deciding whether
to use the power save facility. However, it is also possible to set one RANGE with power save activated and the other
without.
The benefit is that the battery life, based on a 350sensor bridge being connected, increases from 45 hours to 450
hours.
It is also important to remember that when the IPM25 is re-calibrated with a sensor, the power save facility will be
automatically turned off. The power save facility will therefore need to be re-activated after calibration has been
completed.
AUtO OFF Parameter
The AUtO OFF parameter is another power saving feature. It allows for the setting of a time period in minutes,
between 05 and 99 (00 de-activates AUtO OFF). i.e. if this was set to 25, then if the IPM25 detects no keyboard
activity for a continuous 25 minute period, then the IPM25 will power down, to conserve power. If keyboard activity is
detected at any time during the 25 minute period, then the time period is restarted.
This can be a useful feature in a site environment, should the IPM25 be left unintentionally powered on.

rS232 Parameter (option)
This parameter allows the user to enable the RS232 output form the IPM25, by pressing when prompted by
EnAbLEd? On the display, pressing will disable the RS232.
The output format is ASCII. The display value is passed to the RS232 port each time the display updates, with a
carriage return and line feed at the end of each data string. The string information is as follows:-
Baud Rate = 9600 baud
Stop bits = 1
Parity = None
Data bits = 8
Calibration Menu Parameters
SEnS 5.0 Parameter
The IPM25 is factory set to enable calibration with sensors generating an input signal of 5mV/V or less. In the majority
of cases it will not be necessary to read higher signal levels. If however, a higher sensitivity sensor is used with the
IPM25, it will be necessary to gain access to the internal PCB (you must turn the IPM25 off) to move link LK1 to JP1
(see picture below) to allow the IPM25 to accept sensitivities of up to 50mV/V. TEDS should only be used with 5mV/V
as 50mV/V is not factory calibrated.
Once this link has been moved, you will need to go back into the CALIBRATION MENU. When re entering the menu,
you will notice that the parameter SEnS 5.0 has changed to SEnS 50.0 to change the sensitivity to 50mV/V press ,
the IPM25 will now check the position of the link and change the sensitivity. It will now be necessary to re-calibrate any
sensors that you may previously have calibrated to this instrument.
SEt rES Parameter
This parameter enables the setting of two features on the IPM25. It allows you to set the decimal point position of the
display, by pressing the and together, to move the point position (each press moves the decimal point
position, one place to the right).
It also allows for the setting of the display resolution or the number of display counts the display changes with an input
change. To change the resolution use the and arrows to select a digit you want to change and the and
arrows to increment or decrement the digits. Press to accept the value.
CALibrAt Parameter (disabled when TEDS is enabled)
This parameter is used to calibrate and scale the IPM25 with a sensor. There are two basic methods of calibration
available. These are LiVE and tAbLE. There is also a third parameter, which can be used for maintenance and
recording purposes. This parameter is CAL VAL. The CAL VAL value can be viewed after a calibration has been
completed and will show the offset and gain figures from any stored calibration. If these figures are noted, they can be
used to re-enter at a later date, if calibration data is lost for any reason, or if the calibration data from a sensor needs
to be transferred to another IPM25.

Calibration Procedures
The best method of calibration, if it is possible to do so, is the LiVE calibration, as this reads in the sensor signal at
two calibration points and scales the IPM25 automatically. If this is not possible, then the sensitivity figure (in mV/V)
from the sensor calibration certificate can be used to scale the IPM25, by using the tAbLE calibration. This may be the
only option available if you are unable to apply a known stimulus to the sensor, which quite often is the case.
LiVE Calibration Procedure (you must apply the load on the system)
When CALibrAt is displayed press
LiVE ? will now be displayed, press
You will be prompted uSE SC ?, this can be selected if you wish to use the shunt calibration figure from a sensor
calibration certificate (care should be taken that the shunt calibration resistor used originally with the sensor is the
same as is fitted in the IPM25). If you wish to use this press otherwise press
You will then be prompted APPLY LO. At this point ensure that the low calibration stimulus is applied to the sensor
and allow to settle of approx. 3 seconds, then press
You then be prompted with dISP LO. Press to enter the display value required with the low stimulus applied to the
sensor. The value can be entered by using the and button to select a digit and the and buttons to
change the digit. When the value has been set press
You will then be prompted with APPLY HI (unless you chose to uSE SC ?, in which case jump to the next stage) At
this point ensure that the high calibration stimulus is applied to the sensor and allow to settle of approx. 3 seconds,
then press
You then be prompted with dISP HI. Press to enter the display value required with the high stimulus applied to the
sensor. The value can be entered by using the and button to select a digit and the and buttons to
