1, switch 6 on/off button to divide the table into two States unipolar/bipolar two full scale input. SW6=ON, select the unipolar; SW6=OFF, select dual polarity.
2, switches 4 and 5 Select gain. SW4 and SW5 3 combinations, namely SW4=ON,SW5=OFF;SW4= OFF,SW5=ON;SW4= OFF,SW5=OFF. A case study of unipolar, when SW4=ON,SW5=OFF, full scale input 0 to 50mV,0 to 100mV when SW4=OFF,SW5=ON; full scale input 0 to 500mV,0 to 1V; if SW4= OFF,SW5=OFF, full scale input 0 to 5V,0 to 20mA,0 to 10V. It is easy to see, SW4= OFF,SW5=OFF corresponding to a current or voltage DIP switch full range input is combined with the first two DIP switches correspond to the current or voltage full scale input into 100 times-times, 10 times. Switch 4 and 5 Select gain *100,*10,*1.
3, select attenuation switches 1,2 and 3. SW3 3 combinations and SW1,SW2, SW1=ON,SW2=OFF,SW3=OFF;SW1= OFF,SW2=ON,SW3=OFF;SW1= OFF,SW2=OFF,SW3=ON, respectively. Users who use the EM235 module knows that unipolar analog signal range is 0-32000, bipolar analog signal range is -32000-+32000, but in fact this value and gain as well as a full range input voltage between attenuation coefficients of conversion. Positive and negative 2.5V to the full range of bipolar input, positive and negative 5V, 10V positive and negative, for example, SW1= OFF,SW2=OFF,SW3=ON corresponding to positive and negative 10V full scale input is combined with the first two DIP switches correspond to the positive and negative 2.5V, plus or minus 4 times, twice times the 5V voltage relationship. So when the attenuation coefficient is 0.2 select DIP switch SW1= OFF,SW2=OFF,SW3=ON; when the attenuation coefficient is 0.4 select DIP switch SW1= OFF,SW2=ON,SW3=OFF; select DIP switch when the attenuation coefficient of 0.8 SW1=ON,SW2=OFF,SW3=OFF
