Fluke 705, 24mA Loop Calibrator

Fluke's integrated solution for calibration, maintenance of milliamp loops and repair, the 705 current loop calibrator is an ideal cost-effective source and measurement tool.

Delivering a mA accuracy of 0.02% it also provides quick and easy readings due to the simultaneous % and mA display. For 0 to 20 mA or 4 to 20 mA current loop testing and dc voltage from 0 to 28 V, it is supplied with a set of TL75 test leads (726-3624) and alligator clips.

• 0.02% accuracy
• 24 V loop supply with mA measure
• Simultaneous mA and % of span display
• Selectable step/ramp outputs
• mA sourcing, simulation and measurement
• Compact case and protective holster
• Quick battery replacement

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.

9V installed alkaline battery, AC70A alligator clips, C10 protective yellow holster Flex-Stand™, instruction sheet, TL75 safety-designed test lead set, NIST- traceable calibration report and data

Troubleshooting circuits is fuss-free with this loop calibrator from FLUKE. Use it to calibrate and test current loops so you can identify and repair faults promptly to keep your system running safely. You can expect precise current readings thanks to the unit's tight mA accuracy of 0.02%. The results are quick and easy to interpret too, as having readouts as both mA and % means you always get the full picture. As it's protected by a handy yellow holster, this gadget withstands knocks for reliable use in demanding industrial settings.

• Helpful for linearity checks thanks to its dedicated push button for 25% increments
• Switchable between stepped or ramped output to meet your application needs
• 9V battery is easy to change without opening the case and affecting the calibration seal
• 'Span check' function gives you speedily calculated results for zero and span measurements

• Test and measurement devices
• Research and development labs
• Electronics servicing

This product's 24V internal loop supply provides advanced functionality, as it lets you power and read a transmitter at the same time. This eliminates the need for a separate digital multimeter and PSU.
