Technical Specifications; D.1 Measurement Function (Channel 1 And Channel 2); Dc Voltage; Dc Current - AOIP CALYS 150 Mode D'emploi

D. TECHNICAL SPECIFICATIONS
The accuracies quoted apply at + 18°C to + 28°C unless otherwise stated, and are expressed as ± (n % R + C) where R =
The reading and C = a Constant expressed in practical units. The specifications are given for a confidence level of 95%.
They apply to a product placed under reference conditions of measurement defined hereafter:
- Power up unit and warm up for 30 minutes.
- Using instrument not connected to mains (230 V or 110 V).
- Wait for thirty minutes after disconnecting AC/DC power adaptor.
- For weak signals (100 mV / 1 V cal voltage measurement and simulation and Ohm measurement and simulation) using
connections with Y-shaped lugs or bare wires.
- Acquisition in filtered mode (averaged)
The accuracy includes the accuracy of the reference standards, non-linearity, hysteresis, repeatability and long term stability
over the period quoted.
