For the measurement of extremely small DC and AC voltages and currents. A voltage signal proportional to the measurement variable is available at the analogue output and can be supplied to a voltmeter to be used for display. The measurement amplifier is equipped with an operational amplifier and a special pre-amplifier, which provides for a high gain factor, a low offset voltage and long-term stabilisation.
Measurement ranges (with respect to 1 V output voltage):
Voltage: 1 mV up to 1 V
Current: 100 nA up to 100 µA
Frequency range: 0 up to 20 kHz at ? = 1
0 up to 500 Hz at ? = 1000
Input impedance: 10 k?
Input voltage: max. 10 V
Output voltage: max. 10 V
Measurement accuracy: 2 %
Voltage supply: 12 V AC
Dimensions: 175x85x65 mm
Weight: approx. 250 g
