These meters save time by measuring 4 to 20 mA signals (five) times faster than traditional DMMs without opera- tor intervention, offering loop calibration, voltage testing and eliminate time wasting activities. Use the Fluke 771, 772 and 773 to: • Measure 4-20 mA signals without ”breaking the loop,” save time and money troubleshooting 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) or 709H Precision Loop Calibrator 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 Features mA measure w/jaw mA measure In circuit mA source mA sim Loop power 24 V DCV source 0-10 V DCV measure 0-30 V Scaled mA output to mA input mA in/out 771 • 772 • • • • • 773 • • • • • • • • • Specifications Function Resolution and range Accuracy Notes 771, 772, 773 mA measurement 0 mA to 20.99 mA 0.2 % + 5 counts Measured by clamp 21.0 mA to 100.0 mA 1 % + 5 counts 772 and 773 mA measurement 0 mA to 24.00 mA 0.2 % + 2 counts Measured in series with test jacks 772 and 773 mA source 0 mA to 24.00 mA 0.2 % + 2 counts Maximum mA drive: 24 mA into 1,000 ohms 772 and 773 mA simulate 0 mA to 24.00 mA 0.2 % + 2 counts Maximum voltage 50 V dc 773 Voltage source 0 V dc to 10.00 V dc 0.2 % + 2 counts 2 mA maximum drive current 773 Voltage measure 0 V dc to 30.00 V dc 0.2 % + 2 counts Ordering information Models Included accessories FLUKE-771 Milliamp Process Clamp Meter Soft carrying case, users manual FLUKE-772 Milliamp Process Clamp Meter Test leads, alligator clips and hanging strap, soft carrying case, users manual FLUKE-773 Milliamp Process Clamp Meter Measure process and other automation 4 to 20 mA signals without breaking the loop.
