5 Calibrate DAC and select the low voltage calibration point.

30 LEFT

The START BITCAL message is displayed for about

3 seconds to indicate that the power supply is ready for

DAC calibration. Then it counts down numbers from

30 to 0.

V LO 0.5000 V

Then, the display shows the low voltage calibration point.

6 Read the DVM and change the low voltage value on the

display to match the measured voltage.

For example, if the DVM reading is 0.4500 V, adjust the

voltage to 0.4500 V using the knob and resolution

selection keys.

V LO 0.4500 V

7 Pressing the Calibrate key saves the change and selects the

middle voltage calibration point.

V MI 15.000 V

If the entered number is within an acceptable range, an

ENTERED message appears for one second. If the entered

number is not correct, a MIN VALUE or MAX VALUE message

appears for one second and the display shows the low

voltage calibration point again. The display now shows the

middle voltage calibration point.

8 Read the DVM and change the middle voltage value on the

display to match the measured voltage.

For example, if the DVM reads 14.995 V, adjust the voltage

to 14.995 V using the knob and arrow keys.

V MI 14.995 V
