The accuracies quoted apply at + 18°C to + 28°C unless otherwise stated, and are expressed as ± (n % L + C) where L = 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 (230V or 110V).
- Wait for thirty minutes after disconnecting AC/DC power adaptor.
- For weak signals (temperature measurement by thermocouple probes) use connections with spade terminals 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.

Range
Specified
measurement
range
400 Ω
0 Ω à 400 Ω
3600 Ω
0 Ω à 3600 Ω
Temperature coefficient < 5 ppm/°C from 0°C to 18°C and from 28°C to 50 °C.
•
Automatic detection of connection scheme: 2 wire, 3 wire or 4 wire.
•
For 2 wire connection, the measurement includes the resistance of the line.
•
For 3 wire connection, add the out-of-balance of the line resistances.
