Digital Indicator of 2ch Input Type
F350 is a digital indicator that is capable of two-channel inputs of strain gauge type sensors. Equipped with calculation functions, such as ch1+ch2, ch1-ch2, F350 is ideal for total, difference, balance and other load measurements. This is a practical device equipped with compact DIN 96 square size, high-speed sampling at 3000 times/sec on each channel, and an equivalent input calibration function which allows calibration by simply key-inputting the rated value of the sensor without applying an actual load.
