Main characteristics

Fast loop calibration/loop calibration handheld tool can be calibrated by pressing a button.

Fluke 707 Circuit Calibrator (Circuit Calibrator) combines convenient button and knob switch functions. It has the following functions:

Large display screen, fast button interface, one-handed operation

It also displays mA and percentage readings, which are convenient to read.

The accuracy of 0.015% mA is obviously due to other circuit calibrators at the same price level.

Power supply, simulation and measurement of mA with resolution of 1 A

Keyboard control 25% step value, convenient for linear detection.

0-99% span checking function, fast zero and span checking.

The milliampere signal generator can choose slow speed, fast ramp and step function to provide continuous smooth output to test circuit and valve sliding.

It provides 24V circuit power supply, which can supply power to the transmitter and measure its output without carrying a digital multimeter.

Circuit calibrator (milliampere signal generator) can measure up to 28 V DC voltage.

A single 9V battery can be replaced without destroying the calibrated lead seal.

0 - 20 mA or 4 - 20 mA default startup mode

Innovative output adjustment dial with 1 A and 100 resolution

Loop Checker can connect 250_resistors in series in 24V circuit in HART mode, which is compatible with HART communication device.
