Fluke 771 Milliamp Process Clamp Meter, 0.2 Percent Accuracy, 0.01mA Resolution with a NIST-Traceable Calibration Certificate with Data

The Fluke milliamp process Digital clamp-meter is a manual-ranging meter for measuring DC milliampere (MA) and DC Voltage output signals of 24V loop circuits. It has a clamp that measures DC to 100MA. The clamp has two jaws that can close around an electrical conductor up to 4.5mm (0.177 inches) in diameter to measure current without touching or Interrupting the circuit, and has a 1 M extension cable so it can detach from the meter Body for hard-to-reach applications. A set of Test leads is included for measuring DC to 24MA and DC Voltage to 30V. The meter can source and simulate DC signals up to 20MA, can source DC Voltage signals up to 10V, and is accurate to 0.2 percent with a resolution of 0.01MA. It has an LCD that shows both milliamp readings and percent of 4 to 20MA span, and a backlight for visibility in low light that turns off automatically after two minutes. An LED at the top of the meter Body can be illuminated to aid visibility of wires in Dark enclosures. The meter features a built-in 24V loop power supply for powering a transmitter and measuring its milliampere output signal, and a scaled milliampere output for connecting to a logging device (sold separately) to record measurements. To aid documentation of readings and capture readings in tight spaces, the data hold function keeps the most recent reading on the display after disconnecting from the circuit. The unit operates on four 1.5V AA batteries, and turns off automatically after 15 minutes of non-use to conserve battery life. It has a low-battery indicator that signals when the battery needs to be replaced. The meter is manual-ranging, so the user selects the operating range for the property being measured. It meets IEC (international electro technical commission) Safety standards 61010-1 and 61010-2-032, has CE (European Conformity) marking, and complies with CSA (Canadian standards Association), and Australia N10140. The unit comes with a Soft carrying case.
