⌐Periodic calibration of the DA12-16 is recommended when it is used under extreme environmental conditions. Calibration of the DA12-16 includes adjustment of the reference voltage, the zero level, and the full scale gain of each channel on the card. Step through the submenu procedures of the Options menu Calibration command in order to calibrate the DA12-16 when required. Calibration should proceed in the following order: g
 ■ Perform Reference Voltage Calibration
 ■ Perform Zero Level Calibration
 ■ Perform Gain Adjustment

δIn order for communication to be established between your I/O card and its host computer, the I/O card must be assigned a base I/O port address. The setup program scans your system to determine which port addresses are currently available, and it presents you with a list of I/O ports and their availability status. Scroll through this list using the arrow keys or mouse and select an available address, then configure your card's address switch to match the switch settings in the diagram. ][

THelpTopic3  Zero Level Calibration
 ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀
*To adjust the zero level of the DA12-16, all analog outputs are first programmed to their minimum full scale values. Once the setup program has programmed the DA12-16 outputs, adjust the zero potentiometer so that the minimum full scale value can be read over the appropriate channel's test point. ][
THelpTopic%  Gain Adjustment
 ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀
RTo adjust bipolar gain of the DA12-16, all outputs are first programmed to their maximum full scale values. Once setup has set these outputs, take note of the initial channel reading. Adjust the gain potentiometer to one half the difference between the maximum full scale value and the initial value. Example (assume ±full scale = ±5v) : ╜
 ■ Initial channel value observed: 4.9880v
 ■ ½ difference = (5.000-4.9880)/2 = .0060v
 ■ Initial value + ½difference = 4.9940v
 ■ Adjust gain pot for a reading of 4.9940v
 ■ Recheck zero
