calibration equipment

The K800 calibration unit for strain gage quarter bridges launched by HBM can calibrate eight channels simultaneously. The device is particularly useful for multi-channel measuring amplifiers, such as HBM’s MGCplus, that must be calibrated regularly to ensure accuracy.
Multi-channel amplifiers are used for complex measurement applications needing higher channel counts, such as in applications ranging from vehicle road tests through to experimental stress analysis using single strain gages in the aerospace industry.

The K800 comes with five calibration steps for amplifier imbalances of between ±8 mV/V. The steps are individually balanced for each of the eight channels providing a precision resistor network to achieve high accuracy. The unit is fitted with LEDs on the front panel to show the device status at any time.
The calibration unit is an intuitive and easy to operate device that gives faster calibration than sequential calibration of measurement channels. Four versions of the device – 120 ohm, 350 ohm, 700 ohm and 1000 ohm - are available to meet the needs of the most popular nominal strain gage resistances.
