Fluke 705 Loop Calibrator Battery 30V

Fluke Loop Calibrator, 0.02% Accuracy, 0.001 mA Resolution - 0665091

This loop calibrator is a compact, handheld instrument for diagnosing and servicing current loops and voltage signals in industrial process control. Designed for field use, it measures and sources mA and volt signals, supplies loop power while monitoring current, and operates across a typical workshop temperature range for automation and maintenance tasks.

Features & Benefits

• 0.02% accuracy provides precise calibration for critical loops
  0.001mA resolution enables fine measurement and sourcing adjustments
  24V loop supply while measuring mA supports live loop checks
  Simultaneous mA and percentage display simplifies span verification
  Selectable step and ramp outputs assist automated response testing
  Battery operation using AAA cells delivers portable field use

**Applications**

• Suitable for commissioning and troubleshooting 4 to 20 mA transmitter loops
  Ideal for maintenance checks on PLC analogue outputs and inputs
  Used for calibration in control cabinets and on-site process diagnostics
  Can be used for verifying loop power and HART Interface resistances

How long will it run during typical field work?

Typical battery life is 18 h when sourcing at 12mA using AAA cells.

What environmental limits should be observed during operation?
