:FEED A

A = 1 to 255

 

 

Explanation

 

 

Feeds the paper by a distance from 1 to 255 in millimeters determined by the numerical value.

 

 

When allowed

 

 

In all functions.

(except 8720)

 

(7) Performs report printing.

Common

 

Syntax

 

 

command

 

 

:REPOrt

 

 

Explanation

 

 

Same as the FEED key + COPY key of the unit.

Performs report printing.

 

 

When allowed

 

 

In all functions.

(except 8720)

 

(8) Performs automatic range setting.

Common

 

Syntax

 

 

 command

 

 

:AUTO

(except 8720)

 

(9) Queries the unit error number.

Common

 

Syntax

 

 

query

 

:ERRor?

response

A<NR1>

A = error no.

 

 

Explanation

 

 

The number of error or warning that has occurred on the unit is returned in <NR1> as a numerical value.

(For errors or warnings, refer to the instruction manual included with the unit.)

 

 

When allowed

 

 

In all functions.

 

(10) Enables and disables headers, and queries header enablement.

Common

 

Syntax

 

 

command

query

 

:HEADer A$

:HEADer?

response

A$

A$ = OFF, ON

 

 

Explanation

 

 

Sets header enablement.

When headers are enabled, responses to queries are prefixed by headers; when headers are disabled, responses are not so prefixed.

Returns whether or not headers are prefixed to responses to queries.

The initial toggle state for headers (when the power is turned on) is OFF

 

 

Example

 

 

Response to :HEADer?:

(1) When headers are disabled: OFF

(2) When headers are enabled: :HEADER ON

 

 

When allowed

 

 

In all functions.

 

(11) Changes and queries the function selection.

Common

 

Syntax

 

 

command

query

 

:FUNCtion A$

:FUNCtion?

response

A$

A$ = MEM: memory recorder function

         REC: recorder function

         RMS: RMS recorder function

         R_M: recorder and memory function

         FFT: FFT function

 

 

Explanation

 

 

Switches to the function designated by A$.

Returns the name of the current function as character data.

 

 

Example

 

 

:FUNCtion MEM

The function is set to the memory recorder function.

 

 

When allowed

 

 

In all functions.

 

(12) Queries the communication errors. (RS-232C only)

Common

 

Syntax

 

 

query

 

:CERRor?

response

A,B,C<NR1>

A: parity error

B: overrun error

C: framing error

 

 

Explanation

 

 

The number of times of communication errors are returned in <NR1> as a numerical value.
