Specifications
All specifications above are stated for operation at temperatures between 0°C and 40°C. Warm-up time must be greater than or equal to 30 minutes after power on for all specifications.
Electro static discharge Warning
This product, like all electronic products, uses semiconductors that can be damaged by electrostatic discharge (ESD). When handling, care must be taken so that the devices are not damaged. Damage due to inappropriate handling is not covered by the warranty.
Relation between the precision setting and the measurement time and measurement accuracy
Overview of the different range and precision settings
Fig 8: Precision-Range Plot
All specifications refer to measurements done with a Sciospec ISX-3mini in combination with the Sciospec MEArack. The signal amplitude is set to 100mV and the frequency range to ?<10MHz“. Measurements done, using the BNC connectors show very similar results.
Example measurement:
Frequency sweep: 100Hz – 1MHz, 80 logarithmic Frequency steps, precision 1, amplitude 100mV, measurement range MΩ
Measurement instrument: Sciospec ISX-3mini with connected Sciospec MEArack
DUT: Multielectrode array, 40μm electrodes, 200μm apart, platinum PBS buffersolution
