Multi-Sensor Monitoring Workflow
Configuration: Install 34901A module for thermocouple measurements
Connection: Screw-terminal wiring to 20 sensors
Programming: Set Hi/LO alarms with BenchVue software
Operation: Continuous logging to 50k non-volatile memory
High-Channel Density Boundary
When scanning >200 channels at maximum speed, thermal drift may cause ±0.1°C temperature error (based on DAQ system thermal characteristics). Mitigation: ① Enable auto-zero calibration (accuracy improves to ±0.02°C); ② Use thermal stabilization enclosure (lease accessory available).
