The :FUNCtion:AVERage? query returns to the current measurement average times of the
instrument.
Command syntax: FUNCtion: AVERage <value>
Where, <value> is any integer value among the average times range (1

999) of the instrument.

For example: WrtCmd(“FUNCtion:AVERage 12”); set the average times of the instrument as 12.

Query syntax: FUNCtion: AVERage?
Return Format: <value><NL^END>
The :FUNCtion:AVERage? query returns to the average times of the instrument.

The :RANGe command sets the range of the instrument.
The FUNCtion:RANGe? query returns to the current range parameters .
Command syntax: FUNCtion: RANGe <value>
Where, <value> can be 1mA

100uA

10uA

1uA

100nA

10nA

For example: WrtCmd(“FUNC:RANG 1mA”); Set the range of the instrument as 1mA.

The :RANGe:AUTO command sets the range auto selection mode of the instrument.
The FUNCtion:RANGe:AUTO? query returns to the current range mode.
Command syntax:

ON (1)

FUNCtion:RANGe:AUTO

  

OFF (0)

Where,

Character 1 (integer:49) means ON.
Character 0 (integer: 48) means OFF.

For example: WrtCmd(“FUNC:RANG:AUTO ON”); Set the range mode of the instrument as AUTO.

Query syntax: FUNCtion:RANGe:AUTO?

ON

Return format:

<NL^END>

OFF

The :MDISplay command sets the measurement display switch of the instrument.
The FUNCtion:MDISplay? query returns to the current measurement display switch of the
instrument.
Command syntax:

ON (1)

FUNCtion:MDISplay
