3 Important Information for IHH500
3.1 Performance
The IHH500 is a microcontroller based digital handheld instrument that monitors the activity of a vast
range of sensors. This includes Wheatstone bridge strain gauge and amplified output Torque/ Force/
Pressure/ Displacement sensors. All of the measurements are based on a high accuracy, low noise, 24 bit
resolution Analog to Digital Converter with a non-linearity of 0.001% and a temperature coefficient factor
of less than 5 PPM (zero and span drift). All analog components not only those ones that provide the
requirements for ADC such as reference voltage but also the ones which are employed for analog output,
excitation voltage and input/output buffers are low noise, low distortion, low temperature coefficient,
and high precision/accuracy parts. The combination of these components, along with a high speed micro-
controller integrated with a precision DAC controller has provided a high accuracy instrument, which is
able to measure the activity of a 2 mV/V sensor with up to a 500,000 count (total) noise free base! The high
precision DAC controller has been exploited to provide a ± 5 V voltage output with 100 μV resolution
and/or (0-25mA) current output with a 0.5 μA resolution. A wide range of bridge resistances and
input/output impedances of external instruments can be applied to this device without any lack of
performance.
The IHH500 accepts amplified Voltage input (± 12 VDC), Current input (up to 30mA), Bridge input (up to
500 mV/V), and Pulse/ TTL input (up to 650,000 pulses per second) and has the capability to provide
power to FUTEK rotary torque sensors (24 VDC/ 1 W and 5 VDC/ 0.05 W).
