The A75D(E) is now available with a microprocessor controller. This makes the A75D(E) more user friendly and
provides new helpful features to the user.
After the A75D(E) has completed the startup sequence, the “AC ON” and “FLOAT” LEDs should be on and the
display should show the output voltage and current as pictured above in figure 14. The parameter displayed can
be changed by pressing either the UP or DOWN arrows on the membrane.
The parameters that can be displayed, sequence assuming only the down arrow is being used, are as follows:
