Applicable Industries:

• Small Process Plants — Single temperature or pressure monitoring
• HVAC — Room temperature recording
• Food & Beverage — Single-point temperature monitoring
• Water Treatment — Tank level or temperature recording
• OEM Equipment — Embedded recording in machines

Installation Requirements:

• Panel cutout: 45 mm (W) × 90 mm (H) for 1/8 DIN mounting
• Use correct thermocouple extension wire for TC inputs
• Use 3-wire RTD configuration for best accuracy
• Keep input wiring away from high-current cables (minimum 50 mm separation)

Precautions:

• Do not apply more than 30 VDC or 250 VAC between any input terminals
• Do not exceed rated input range — will cause permanent damage
• Ensure proper grounding of the recorder chassis
• Backup data to USB drive periodically — internal memory has limited write cycles
