Fluke 709H calibrator is designed with a user-friendly interface and a Quick-Set rotary encoder knob. The tool reduces the measurement or output time of voltage and current and the charging time of the circuit. Protective leather jackets are especially suitable for technicians to hold. Large backlight displays are easy to read, even in dark and narrow working areas. The characteristics of 709H calibrator:
0.01% reading accuracy
Designed to be compact and durable, powered by six standard AAA batteries
Visual user interface, Quick-Set knob can be quickly set up, easy to use
250 Optional Resistors for Built-in HART Communication
24 V DC circuit power supply with mA measurement mode (-25%-125%)
The current range resolution is 1 A and the voltage range resolution is 1 mV.
All measurements are made by simple two-wire connection.
Automatic shutdown to extend battery life (up to 30 minutes)
Variable step and slope time (seconds)
Selection of adjustable span (0-20 mA or 4-20 mA)
Electron tube test (using% bond to simulate defined mA values)
HART specific performance includes:
Fast transmission of calibration data. 709H/Track software/cable can record all HART transmitter parameters on your device in (.csv) or (.txt) format.
Data can be recorded on a specific transmitter to facilitate troubleshooting. The data recording tool has an optional acquisition interval of 1-60 seconds and can record 9800 records or 99 individual sessions. Each data sample contains 709H measurements, all four process variables and standard state 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 operation could only be accomplished by a dedicated communicator, a high-end multi-functional calibrator or a laptop computer equipped with a HART modem. Fluke 709H allows almost any technician to repair and support HART devices.
