6. General hints
Do not close the machine with highest speed, as this may cause offset because of the strong vibration.
If the display does consistently not display zero after releasing the reset button, (e.g. if it displays values between approx.
+25 to -25), that means very often, that ground electrical loops exist on the machine. To avoid this, connect the ground
of the display box or the monitor with the included black cable and clamp to the machine ground or the platen.
Compatibility: the QE-1008 are fully compatible (= generate the same signal) as bonded strain gauges, strain rings or
strain clamps.
7. Calibration intervalls
This measuring instrument should be calibrated every 12 months. The sensors, monitors and cables should then be sent to
the manufacturer.
If the foil is damaged, or the 350 Ohm can not be measured anymore, then the sensor has to be sent back for repair or
overhaul and calibration.
RECOMMENDATION: If the extensometers are used heavily, then we recommend to purchase one or two sensors more
then actually necessary. This assures that the system can still be used even if one sensor is out of order or currently at the
factory for calibration.
