Measuring current < 0.3 mA
Sensor line resistance ≤ 50 Ω per line for 3- and 4-wire circuit
≤ 100 ohms line resistance for 2-wire circuit
Lead compensation Not required for 3-wire or 4-wire circuit. In 2-wire circuits, lead compen-
sation is performed in the software by entering a fixed line resistance.
Special features - Can also be programmed in °F
- Basic sensor type can be changed with sensor factor (e.g., Pt50 to
Pt100)
