Features
- Measure and simulate 8 thermocouples
- Measure and simulate Pt100-RTD
- Measure and source μV/mV/mA
- Displays units in °C, °F , μV/mV , or mA
- Automatic or manual cold junction compensation
- 10 point memory recall
- Process loops 4 to 20 mA and 0 to 50 mA
- 24 V loop drive voltage
- Mains or battery operation
- 60 hours typical use between charges Memory recall and step/auto-step functions Up to 10 values can be stored in the unit’s non- volatile memory and they can be recalled at any time. The user can also manually step through them in sequence using the step key. Continuous stepping (auto-step) is also available at any user selectable rate between 1 and 10 seconds/step. Power is via an internal high capacity rechargeable metal hydride battery that can be recharged from an external mains charger (supplied as standard). An auto power-down feature helps conserve battery lifeby switching off the instrument if inactive for over 5 minutes. This can be disabled if not required. The unit is supplied in a robust case with a carrying strap. A pocket for the instruction manual is provided.
