Then press SHIFT, then  to change to next step.
In above step C of V OUT AND MEAS. ACCURACY CALI., the user should not turn on the
load. Press
ENTER, then check the output voltage measured by DVM is about 15VAC.
This step is just to make sure the connection is correctly.
Then go to next step D. Press ENTER, check the output voltage measured by DVM is about
150VAC. Keyin the exact value measured by DVM, then press ENTER .
Then press SHIFT, then  to change to next step.
In above step E of V OUT AND MEAS. ACCURACY CALI., the user should not turn on the
load. Press
ENTER, then check the output voltage measured by DVM is about 30VAC.
This step is just to make sure the connection is correctly.
Then go to next step F. Press ENTER, check the output voltage measured by DVM is about
300VAC. Key in the exact value measured by DVM, then press ENTER.
Step F is the final step of V OUT AND MEAS. ACCURACY CALI. Press PAGE/EXIT to exit
that page. Then display will show as below. Press ENTER to save the calibration results.
