Fluke 771, 772 and 773 mA Process Clamp Meters
Recommended Accessories
Don’t break the loop on 4-20 mA signal measurements and save time with the Fluke 771, 772 and 773 Milliamp Process Clamp Meters Three year warranty, (one year provided on mA clamp assembly and cable) Use the Fluke 772 and 773 to: • Source 4-20 mA signals for testing control system I/O or I/Ps • Simulate 4-20 mA signals for testing control system I/O • Measure 4-20 mA signals with in-circuit measurement • Power a transmitter with the 24 V loop power supply • Automatically ramp and step change the 4-20 mA output for remote testing Use the Fluke 773 to: • Measure DC voltage to verify 24 V power supplies or voltage I/O signals • Source DC voltage to test voltage input devices • Scaled mA output signal enables a logging DMM (289) to record 4-20 mA signal without breaking the loop • mA in/out: simultaneously source a mA signal while measuring a mA signal with the clamp

Fluke 771, 772 and 773 mA Process Clamp Meters pay for themselves • The more you use them the more money you save • Measuring 4-20 mA signals (five) times without operator intervention can pay for the 771 • Saving a trip back to shop to get a loop calibrator can pay for the price difference of the 772 • Saving a trip back to the shop for a voltage test source can pay for the price difference of the 773
