Calibrating Analog Outputs

After launching DaqCal, select the device to be calibrated from the device inventory list.
After selecting your device, click the <OK> button. An instruction screen with a Calibration List will display.
From the screen's Calibration List select the desired types of
calibration. For the example we have selected:
System Positive Reference D/A
o
o System Negative Reference D/A
After making the selections, click the <Calibrate> button
(see preceding figure). Steps specific to your Daq device
will now display.
Follow the DaqCal screen prompts. You will
likely see instructions similar to the following:
Connect the multi-meter positive (+) lead to Pin 9
(Positive Reference) of DBK11A.
Connect the multi-meter negative (-) lead to Pin 19
(SGND) of DBK11A.
Note: A multi-meter with a 6 ½ digit accuracy is
required.
Click <Go To Next Step.>
In continuing to follow DaqCal screen prompts you will be instructed to enter
the DVM reading into the numeric field on the screen.
Click <Go To Next Step>.
This procedure is repetitive and DaqCal will instruct you step-by-step.
Eventually, for example, after eight DVM voltage entries, a message similar
to the following will be displayed:
"No further steps in this section. Please click <OK> to continue."
