2.3.1 V-set (set up a constant voltage from 0 to 36V)

  Set up a constant DC voltage output is the first main function of programmable DC power

supply, 3645A power supply provides two methods to set up the constant DC voltage output by

using the number keyboard and the rotary button. Please see the following operation procedure.

For example, how to set up the output voltage at 24.3V

1. To set up by using number keyboard

 Step1. Press “V-set” button,

 Step2. Enter the password by using the number keyboard (if the keyboard is unlocked,

             please do step4),

 Step3. Press Enter button (if the password is wrong, please do step2 for reentering),

 Step4. Press “2”, “4”, “.” and “3” button to enter the voltage value,

 Step5. Press “V/A” button to confirm the voltage value.

2. To set up by using Rotary SW

(1) If the key board is unlocked by password, directly rotate the “Rotary SW” button, and the

voltage will be continually changed from the previews value according the rotation. At the

beginning, the cursor will be shown on the last number of the value which is indicated on the

LCD, you can move the cursor to the first number, second number etc by using “      ”and “       ”

buttons, and then rotate to change each number, and let it stay at 24.3 V, then confirm the value

by pressing “V/A” button.

 (2) If the keyboard is locked by password

Step1. Press “V-set” button,

Step2. Enter the password by using the number keyboard,

 Step3. Press Enter button (if the password is wrong, please do step2 for reentering),

 Step4. Rotate the Rotary SW button to change the value, the operation is as the same as item(1)

 Step5. Press “V/A” button to confirm the voltage value.

  Step 1        Press “V-set”                                                                             24.00V   0.00A

                                                                                                            0.00W   ON

 Step 2         Enter the password ( Or jump to  step 4 if the keyboard         ENTER PASSWORD

                     is unlocked)

 Step 3         Press “Enter” button ( it will return to step 2 if your               ENTER PASSWORD

                    password is wrong  for reentering)                                             ****

 Step 4         Press “V-set” .Set the voltage voltage to 24.00V by using        SET VOLT= 24.00V

                    the number key or the rotary code switch.Then pyess              NEW=

                     “V/A” to confirm the set

  Step 5        Press “mV/mA” button to change the voltage unit into mV,     SET VOLT= 24.00V

                     it will return to step 4 for reentering if the current voltage        NEW= 18

                      exceed the high limited voltage value

     It will exit the setting up voltage operation at any procedure by press ESC button
