Ttl technologies supplies fluke 771 milliamp process clamp meter. It is used for measuring 4-20 ma output signals from transmitters in process and industrial control system applications without breaking the current loop. The accuracy level of the clamp meter is 0.2 per cent. It is also designed with resolution and sensitivity to 0.01 ma for testing and solving plc and control system analog input/output. This is particularly designed for use in the situation when it is impractical to close processes or put systems into "safe` mode in order to break the loop and place a meter in series with the circuit and take measurements. It has an excellent detachable clamp, which can be used docked or detached via its extension cable to facilitate measurement in tight spaces, a measurement spotlight that illuminates wires in dark enclosures, and automatic battery saving features. This process clamp meter comprises a dual backlit display that shows both ma measurement and percent of 4-20 ma span and a hold function to capture and display changing measurements for convenient viewing. The measurement of 10-50 ma signals is also possible in older to control systems using the 99.9 ma range.
