EX Series Operating Manual
6-9. ADC SAMPLING
▌Be able to set the output voltage/current measuring speed and displaying speed.
▌If the frequency is lower, data acquisition is reduced. But you can get the more accurate value.
▌If the frequency is higher, data acquisition is increased. But voltage/current measuring value
can be changeable frequently in the display.
▌In case of PC interface control, recommends ADC sampling speed is 20~50Hz.
