Measure low DC voltage with this device’s highly accurate and stable output. The unit features a five decade range with 100% over-ranging. Readings are directly obtained on 3 1/2 digit digital panel meter featuring a seven segment LED with autopolarity and decimal indication. Its well-designed chopper stabilized IC amplifier offers exceptionally low offset voltage and input bias parameters, combined with excellent speed characteristics. A filter circuit is provided to reduce the line pickups of 60 Hz and all internal power supplies are IC regulated. This microvoltmeter also offers very low temperature drift and low (10 pA) input bias current. 100V ±10%, 60 Hz. Size: 24.5 x 28 x 12cm; weight: 2.5 kg. Specifications: Range: 1 mV, 10 mV, 100 mV, 1 V & 10 V with 100% over-ranging Resolution: 1 μV Accuracy: ±0.2%, ±1 digit Stability Within: ±1 digit Input Impedance: <1000 M (10 M on 10 V range)
