Key Features of Hand Held Portable Online Current Loop Calibrator

• It generates current signal [mA] for instruments calibration and testing
• It`s patented; unique current generation technique dynamically isolates the actual transmitter loop current and presents user set current to the loop sensing instruments. Thereby allowing online testing of the instruments.
• No need to isolate the measuring instrument for the test/calibration.
• The instrument wiring is not disturbed.
• Transmitter loop current is unaffected.
• Other instruments sensing the same loop current are also unaffected
• Output current range: 0.00 - 21.00mA.
• Output adjustment: using fine and coarse knobs.
• Accuracy ± 0.015% of span.
• Current output load, selectable from 50 to 250 Ohms.
