Units with LabJack U12.

* * Safety Warning * *

Although the Thimble is not electrically connected to neither the test subject nor the investigator, it is highly recommended to use a laptop computer not connected to a main power outlet. The algometer itself is powered through a medical grade power supply, but the USB data acquisition unit is a LabJack U12 that will not function through the B&B Electronics UH401 USB to USB isolation device. (B&B UH401).

Units with Analog "Force" Output

These units are equipped with an Analog Devices AD210 isolation amplifier to output the "Force" detected by the force sensing resistor (FSR). An additional 15 vdc Condor medical power supply was added to feed the AD210.

Units with LabJack U3.

Standard Units

These units are equipped with a LabJack U3 DAQ unit that is compatible with the B&B UH401 USB to USB isolator which makes it safe for use with desk top and recharging laptop computers. The enclosure will be 6" wide instead of 9".
The software user interface is the same as the VB.NET version for U12.

Should there be any request for a "Force" BNC output, the same Analog Devices AD210 isolation amplifier and the Condor 15 vdc medical grade power supply will be added requiring the wider 9" enclosure as used for the U12 versions.

Units with Analog "Force" Output

These units are 9" wide to have room for an Analog Devices AD210 isolation amplifier to output the "Force" detected by the force sensing resistor (FSR). An additional 15 vdc Condor medical power supply is added to feed the AD210.
