Buying Guide – Real Experience Tips

• Check your cable length needs.
  • This model has 1.0 meter cable.
  • For longer runs, choose 2, 5, or 9 meter options.
  • Extension cables also available separately.
• Match temperature class to your machine.
  • For T4 rating, max ambient is 80°C.
  • For T1 rating, max ambient is 232°C.
  • Check the table above for your zone.
• Do not overtighten the probe case.
  • Max torque is 7.3 N·m (65 in·lb).
  • Use a torque wrench for best results.
  • Over tightening strips threads or cracks case.
• Keep cable bend radius large.
  • Minimum 25.4 mm (1 inch).
  • Tighter bends break inner conductors.
  • Use cable supports for long runs.
• Order spare connectors with your probe.
  • ClickLoc connectors are durable but can wear.
  • Spares save downtime later.
