INSERT, DELETE, NEW, SAVE or select up or down by pressing the F1~F6.

Press the right arrow key to move the cursor to the test mode option, as shown in Figure 4-12,

uses the F1~F5 keys to select whether the test mode is AC withstand voltage, DC withstand

voltage, insulation resistance, pause mode or open short circuit detection OSC.

Move the cursor to the test parameter in the corresponding mode by using the arrow keys and

change the parameter setting by using the F1~F6 keys or numeric keys.

Figure 4-11 Meas Setup

Test procedures: current setting step number / total number of test steps. The change of the test

steps are as shown in the table below:

Key Function

Explanation

INSERT

Add a new test item. The current item and subsequent items

will move one step backward.

DELETE

Delete the current test item. The subsequent item will move

one step forward.

NEW

Create a blank test program (PROG). Please remember to

save the test program after finishing writing.

SAVE

Save the current test file

Move to the display screen of the previous step of the current

step.

Down

Move to the display screen of the next step of the current step.
