  A1 1mV/digit Approx. 10msec.
(60% response)
This value has been calculated as response frequency (= 1/2T (Hz)) based on the measured step response (0–100%) and rise time (T) with the sensor bridge resistance of 350Ω. Response frequency is determined by the sensor to be used. Consult with us when focusing on response. 10kΩ or more (Output impedance 100Ω)
