Fig. 7 Programmable output voltage
Middle display is used for showing the current output voltage for the active channel,
which itself is indicated by the middle column of LED’s. Pressing middle SELECT button
allows you to change the active channels. To edit currently preset voltage, SELECT button
must be held until LED starts blinking. Then SET+ and SET- buttons can be pressed to
adjust currently selected channels voltage. All other inactive channels still keep the same
preset voltage until it’s changed by SET buttons on the side of the board.
Example
1. Connect the
DAC1
output to the ± 5 V voltage measuring channel input.
2. Using middle select button switch the current output channel until
DAC1 Out
LED
lights up.
3. Using left select button switch the measure channel to ± 5 volts.
4. Hold
SELECT
button until
DAC1 Out
LED starts to blink.
5. Using
Set+
and
Set-
button change the output value of the DAC1 channel.
6. Observe that voltage measure display follows the same value as the DAC output one.
