Fluke 707EX, 24mA Loop Calibrator - RS Calibration

Extremely fast and easy to use, Fluke offers a push-button and knob-base current loop calibrator which is an intrinsically safe instrument for use in potentially explosive environments. Designed for high performance one handed operation, calibration, maintenance, measurement and repairs of current loops, assisting users in working more accurately and efficiently.

A clear large simultaneous mA and % of span display, alongside the simple rotary button allows adjustments and quick selections with one hand. Housed in a robust protective case, the 9V battery can also be changed without breaking the calibration seal.

• -10ºC to 55ºC operating temperature
• Simultaneous mA and % display
• 0-100% span check
• 24 volt internal loop supply
• HART® compatible resistance connected in series with the loop supply for compatibility with HART communicators
• 0.015% mA accuracy
• 1 μA resolution for mA source, simulate, and measure

Current loop calibrators are specially designed instruments for current loop trouble shooting, testing and calibration. They can source current on unpowered devices in a loop, simulate the operation of loop powered transmitters and also measure current. These calibrators often feature time saving technology, specialist graphics using digital interfaces and micro-processor based electronics.

Determined by Ohm's law, which states that the current between 2 points through a conductor is directly proportionate to the voltage across those 2 points, divided by the resistance of the conductor. I = V/R. This is also the case for series and parallel circuits, however in parallel circuits the total current can be affected by the way the resistors have been connected, as well as their ohmic value. Current does divide up and there can be more current in one area over another nonetheless when all areas are added up the total amount is the same.
