Why does Kistler 9215A charge amplifier reach the limit during measurement?
The charge amplifier may reach its limit because the force being measured is too high for the selected measuring range. Try selecting a wider measuring range on the charge amplifier. Alternatively, the input stage of the measuring instrument could be defective, requiring the MOS-FET or operational amplifier in the measuring instrument input stage to be exchanged.
What to do if there is no measuring signal at the output of Kistler 9215A Accessories charge amplifier?
If there's no measuring signal, first check the measuring arrangement, including all connections and cables, to ensure they are properly connected. If the connections are correct, the charge amplifier may be defective or not in measurement mode; in this case, proceed according to the instruction manual for the charge amplifier. A defective Low Level Force Sensor can also cause this issue, requiring repair at the factory; proceed according to section 7.2.
How to fix quasistatic measurements not possible (signal affected by strong drift) with Kistler 9215A?
Quasistatic measurement issues with strong drift often stem from poor insulation resistance in the measuring chain. To resolve this, determine the error source in stages. Start by checking the drift with an open or shielded sensor input at the measuring instrument, then repeat the measurement with the cable connected but without the sensor. Also, check the insulation resistance of the sensor and cable using a Kistler insulation tester Type 5493. Cleaning the connectors may also help.
