Explanation of command

4.2.31

DLOW=

(setting of low limit of leak current of DC withstanding voltage test)

Function

Makes the setting of low limit of leak current of DC withstanding
voltage test.

Structure

DLOW=

Low leak current

Low leak current OFF or 0.0~10.9mA is to be set.

Note

: Set value of low leak current can not be higher than high limit

value of leak current.

Transmission

DLOW=2.0mA



…….. Sets the low limit of leak current of DC withstanding

voltage test at 2.0mA.

Response

When 8526 received the effective command setting.

ERROR=0



…….……. When the Response Setting is ON.

No response …………….. When the Response Setting is OFF.

4.2.32

DLOW?

(read-out of low limit value of leak current of DC withstanding voltage test)

Function

Reads out the low limit value of leak current of DC withstanding
voltage test.

Structure

DLOW?

Transmission

DLOW?



Response

DLOW=2.0mA



…….. Indicates the low limit of leak current of DC withstanding

voltage test 2.0mA.
