Measuring amplifier for recording very small voltage, current and charge. For display purposes, any DC meter capable of measuring in the range up to 10 V can be used with no additional configuration. Including offset correction and polarity switch.
Additional outputs are provided so that the -15 V and +15 V operating voltage can be tapped for use in external circuitry, e.g. bridge circuits.
Input: BNC sockets
Measuring range with reference to 1 V output voltage:
Voltage: 0.1 mV – 100 V, 7 ranges
Current: 10 pA – 10 µA, 7 ranges
Charge: 10 pAs – 100 nAs, 5 ranges
Input resistance: 10 MΩ (voltage), compensated 0 Ω (charge, current)
Overvoltage protection: up to 300 V
Precision: typically 3%
Signal output: 0 – 10 V, configurable zero point, polarity switch
Fixed voltage output: ±15 V, max. 50 mA
Dimensions: approx. 235x230x180 mm³
Weight: approx. 2.8 kg
