B1-12 is designed for calibration of digital voltmeters and analog-to-digital converters, DC, as well as for accurate measurements of DC voltages using a differential method in laboratory and production environments. The reading indicated when measuring DC voltages digital display of the zero-body, converted to analog form to issue it on an external recorder.
B1-12 is used as a DC amplifier with gains of 1, 10, 100.
Specifications The calibrated range of output voltages 1*10-7 - 1000 In (0,1-1-10-100-1000 In)
The calibrated range of output currents 1*10-9 - 1*10-1 And
Measuring range DC voltage 10-6 - 1000 (1 - In 10-100-1000)
Basic error:
the installation of calibrated currents, taking into account the error measures EMF: ≤ 1*10-4 I +1*10-5 In (1 and 10 mA) and 2.5*10-4 I+1*10-5 In (100 mA);
digital to analogue conversion ≤ (4*10-3 Un +3) mV, where PI is a numeric indicator of zero-body, In - the nominal upper limit set sub-band
Drift set level of the output voltage over 8 hours does not exceed ± (1*10-5 IR + 1*10-6 SP )
Maximum load current: 110 mA (100 V) to 11 mA (above 100 V)
Output impedance: 10 Ohm (0.1 V), 100 Ohm (1 In), 0.001 Ohm (10, 100, 1000)
The input resistance of 109 Ohms (for all subbands)
Power consumption 100 VA
Overall 490Х175Х478 mm
Weight 22 kg
