Fluke 709H Precision Loop Calibrator with HART Communication/Diagnostics

The Fluke 709H calibrator is designed with a user-friendly interface and a Quick-Set rotary encoder knob. This tool reduces the time it takes to measure or output voltages and currents, as well as the time it takes to energize loops. The protective holster is ideal for technician's hands and the large backlit display is easy to read, even in dark, confined work areas. 709H Calibrator Features:

• 0.01% Reading Accuracy
• Compact and durable design, powered by 6 standard AAA batteries
• Intuitive user interface with Quick-Set knob for quick setup and ease of use
• Built-in 250 Ω optional resistor for HART communication
• 24 VDC loop power supply with mA measurement mode (-25% to 125%)
• Current range resolution of 1 µA, voltage range resolution of 1 mV
• Simple two-wire connection for all measurements
• Automatic shutdown to extend battery life (up to 30 minutes of adjustable shutdown time)
• Variable step and ramp times (seconds)
• Adjustable span selection (0 to 20 mA or 4 to 20 mA)
• Electron tube test (using % key to simulate defined mA values)

HART specific properties include:

• Fast transfer of calibration data. The 709H/Track software/cable logs the parameters of all HART transmitters on your device in (.csv) or (.txt) format.
• Data can be logged on a specific transmitter for easy troubleshooting. The data logging tool has selectable acquisition intervals from 1 to 60 seconds and can record 9800 records or 99 individual sessions. Each data sample contains the 709H measured value, all four process variables, and standard status conditions.

In communication mode, users can read basic device information, perform diagnostic tests and fine-tune the calibration of most HART transmitters. In the past, this could only be accomplished with a dedicated communicator, a high-end multifunction calibrator, or a laptop with a HART modem. the Fluke 709H allows virtually any technician to repair and support HART devices.
