Fluke 789 Multi Function Calibrator, 1A ac, 1000V ac, 203 x 100 x 50mm

Combining the functionality of a current loop calibrator with the power of a digital multimeter, Fluke's 789 also has the wireless capabilities of Fluke Connect with the IR3000FC module.

Featuring a larger display than the Fluke 787B, it has 2 levels of back-lighting making it twice as bright and easy to read. With a built-in 250 ohm HART® resistor, the need to carry a resistor separately has now been eliminated, and a separate power supply is no longer needed with the 24 volt loop supply. This cleverly designed instrument now allows technicians and engineers to do a lot more in one handy tool. The perfect addition to any test kit for measurement and troubleshooting.

• 1200 ohm drive capability on mA source
• 0% and 100% toggle between 4 and 20 mA sourcing
• -20°C to 55°C operating temperature
• 140 hours typical (measurement), 10 hours typical (sourcing 20 mA) battery life

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.

Amp up your troubleshooting capabilities with this multifunction calibrator from FLUKE. As it combines the functions of a loop calibrator and digital multimeter, you can check every part of a control loop using one tool, which gives you an on-site advantage. If you're doing offline transmission testing, don't sweat – the handy instrument comes with a 24V loop supply. This means you don't have to lug around an additional power source. Enhanced two-level backlight settings let you choose the screen brightness that's just right for your environment. As this process meter simultaneously displays both mA and percentage of scale readings, you benefit from lightning-fast diagnostics.

• Buttons to quickly toggle between 4 and 20mA sourcing
• Overvoltage protection reduces the risk of equipment damage
• Resists shock and vibration for safe use in harsh locations
• Compact dimensions of 203 (L) x 100 (W) x 50mm (H) make it easily portable

• Testing and research facilities
• Electrical engineering
• Industrial process control
• Pharmaceutical manufacturing

Yes, you can use this process meter with the FLUKE Connect app to wirelessly monitor, log and share data from your shop floor.
