The Fluke 773 is designed to let users measure 4 to 20mA signals without breaking the loop, saving time and effort when carrying out testing procedures.
This device is the best overall process clamp meter available from Fluke and includes a massive selection of advanced features designed to make your time spent testing as simple as possible. In addition to carrying out no-break-loop testing of 4 to 20mA signals this device can also measure 10 to 50mA signals in older control systems by using the 99.99mA range mode and it can also carry out in-circuit measurements, can be used to source signals for testing control systems (I/O and I/Ps) and much more.
This process clamp meter also includes a detachable clamp with extension cable for measurement in difficult, tight locations, can be used to source and measure VDC, can power a transmitter and includes a dual backlit display which shows both mA measurements and percent of 4 to 20mA span.
To aid with testing in darkened areas the Fluke 773 also includes a measurement spotlight for easy spotting hidden wires.
