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.
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.
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.
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.
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.
Menu Structure Menu Structure The IHH200 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. 10 Thomas, Irvine, CA 92618 USA T (949)-465-0900 F (949)-465-0905 futek@futek.com www.futek.com/support/IHH200 IHH200 Manual 2.
A Calibration Menu is used to calibrate each of the tow ranges with independent scales, as well as setting the display resolution for each range. 10 Thomas, Irvine, CA 92618 USA T (949)-465-0900 F (949)-465-0905 futek@futek.com www.futek.com/support/IHH200 IHH200 Manual 2.
Millivolt per Volt Calibration Menu Structure To access the millivolt CALIBRATION MENU, press and hold 10 Thomas, Irvine, CA 92618 USA and for 10 seconds T (949)-465-0900 F (949)-465-0905 futek@futek.com www.futek.com/support/IHH200 IHH200 Manual 2.
Configuration Menu To enter the CONFIGURATION MENU, press and hold the Parameter SEt ZEro and buttons for 3 seconds. Set-Up Information Press to skip to next menu item Press to set a new system zero This allows the user to introduce a fixed offset to the display value. The GROSS and TARED values are then displayed with this offset taken into account.
Parameter SEt OPEr Set-Up Information Press To skip to next menu item. Press To select operation mode. This allows the enabling or disabling of the power save mode, which updates at 1 update per second and pulses the sensor excitation. This results in a lower accuracy (1 part in 20,000). To enable press . To disable press . Press To skip to next menu item. Press To set auto power off. This enables the setting of an auto power off value. The value entered is in minutes.
Calibration Menu To enter the CALIBRATION MENU, press and hold the Parameter SENS 5.0 and buttons for 3 seconds. Set-Up Information Press To skip to next menu item Press To change sensor input sensitivity This allows the calibration engineer to change the sensitivity range of the IHH200 when connecting to sensors with a sensitivity of greater than 5mV/V. The IHH200 is factory set for 5mV/V.
Parameter Set-Up Information ENABLING TEDS DISABLES CALIBRATE MENU tedS Press to skip this parameter and exit menu. Press to enable or disable TEDS. If you have chosen to enter the TEDS calibration, EnAbLEd? appears. If you have chosen to enter the TEDS you will be prompted whether you want to select EnAbLEd? If you do not press flashing indicators will appear. , press .
Millivolt per Volt Calibration Menu Structure To enter the MilliVolt per Volt Calibration Menu, press and hold the Parameter 5.0 gAIn buttons for 3 seconds. Set-Up Information Press To skip to next menu item Press To change the 5mV/V gain. Here the factory gain calibration can be changed to a measured value (see Milli-Volt Calibration Procedure - back end of manual). Once the derived value has been entered press 5.0 OFFS and Press to skip to next menu item Press to change the 5mV/V offset.
Operation Features Normal Display Operation The IHH200 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 valley values. It is also possible to hold the display value (this only operates when not in peak or valley mode). The display update rate, decimal point position and resolution can be set to suit. The IHH200 has two independent ranges.
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 annunciator 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 IHH200 is in either peak or valley hold mode.
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 TARED 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.
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, and if the IHH200 detects no keyboard activity for a continuous 25 minute period, then the IHH200 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.
Calibration Menu Parameters SEnS 5.0 Parameter The IHH200 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 IHH200, it will be necessary to gain access to the internal PCB (you must turn the IHH200 off) to move link LK1 to JP1 (see picture below) to allow the IHH200 to accept sensitivities of up to 50mV/V.

Millivolt pert Volt Calibration Procedure This procedure outlines how a millivolt per volt calibration might be undertaken. 1. 2. 3. 4. 5. Ensure that the factory settings for gain and offset are set to 1 and 0, respectively. See millivolt per volt calibration section to do this. Begin by connecting up the model IHH200 and a high precision Multimeter to the calibration source set at 2.5mV/V with a 350Ω load. Take readings at 2.5mV/V and 0mV/V on both the model IHH200 and the high precision Multimeter.
