True RMS Digital Voltmeter

 Main Characteristics
- Four measurement ranges: 0.1 V, 1 V, 10 V, 100 V
- Voltmeter bandwidth: 20 Hz to 1 MHz (basic accuracy ±1.0 % of full scale)
- Frequency counter bandwidth: 1 Hz to 10 MHz (typ.), 25 MHz (max.) (±timebase error)
- Minimum input voltage for counter: approximately 50 mVRMS
- Input impedance: = 1 MO || = 50 pF
- Counter timebase: 100 ms, 1 s
- Adjustable trigger level: approximately ±0.15 V
- Autoranging (may be disabled)
- Offset correction and calibration facility
- Automatic scaling of frequency display
- Voltage displayed as RMS value or peak-to-peak value (for sinusoidal input)
- Crest factor: =4
- Two measurement inputs
