Fluke 705, 707, and 715 loop calibrators
F705/F707/F715 Product Features: - Fluke 707's revolutionary dial-type output adjustment disc with 1 μA and 100 μA resolution for one-handed operation
- Large display, simple interface, easy to use
- Simultaneous display of mA readings and % readings allows quick and easy interpretation of readings.
- Fluke 707's HART TM mode connects a 250 Ω resistor in series with a 24 V loop to match the HART communicator
- The button controls the 25% step value for easy linear detection. The “range detection” function quickly switches between and confirms between zero and full scale. The slow and fast linear step ramp function provides ramp output signals for fast valve positioning, remote testing and loop functional testing.
- 0 to 20 mA or 4 to 20 mA default startup mode
- Measure voltage output process signals from PLCs and transmitters (Fluke 715 only)

Fluke 709 and 709H Precision Loop CalibratorsProduct features - Industry's best 0.01% reading accuracy
- Compact and durable design with 6 standard AAA battery powered intuitive user interface, Quick-Set knob for quick setup and easy to use
- Built-in 250 Ω optional resistor for HART communication
- 24 V DC loop power supply with mA measurement mode (-25% to 125%) with a current range resolution of 1 μA and a voltage range resolution of 1 mV. All measurements are made with a simple two-wire connection.
- Auto power off to extend battery life (up to 30 minutes for shutdown) Variable step and ramp time (seconds)
- Adjustable span selection (0 to 20 mA or 4 to 20 mA)
- Tube test (using the % key to simulate the defined m A value)
- The Fluke 709H has a built-in HART modem for communication to read information: read tags, descriptors and calibration dates; read sensor PV information; read PV output information; read long tags; PV range (upper and lower limits); enter/exit fixed current mode; adjust zero offset; fine tune Dac zero (mA output: 4 mA;) fine tune Dac gain (mA output: 20 mA)
