Technical content

Use the Fluke 772 and 773 to:

  • Measure 4 to 20 mA signals without ”breaking the loop” just like the innovative and popular Fluke 771 Process Milliamp Clampmeter
  • Source 4 to 20 mA signals for testing control system I/O or I/Ps
  • Simulate 4 to 20 mA signals for testing control system I/O
  • Measure 4 to 20 mA signals with in-circuit measurement
  • Simultaneously measure mA in-circuit with 24 V loop power for powering and testing transmitters
  • Source mA output signals in a linear ramp or 25 % step output – Automatically change the 4 to 20 mA output for remote testing
  • Power saving features, auto-off, backlight timeout extend battery life Fluke 773 features:
  • DC voltage measurement to verify 24 V power supplies or voltage I/O signals
  • Source dc voltage to test input devices that accept a 1 to 5 volt or 0 to 10 volt signal
  • Scaled mA output provides a continuous mA signal that corresponds to the 4 to 20 mA signal measured by the mA clamp – Output mA signal enables a logging DMM (289) or other device to record the 4 to 20 mA signal without breaking the loop
  • mA in/out: simultaneously measure the mA signal with the clamp and source a mA signal – Apply a mA input signal to a device and measure its’ 4 to 20 mA output on devices such as valves or mA isolators
  • Voltage output linear ramp or 25 % step output – Automatically change the voltage output for remote testing mA measurements without breaking the loop. Save time. Save money.
