Second Level Modifier Commands

DELTA [<nrf>]

Selects the Delta % function and optionally sets the reference value; if no reference is specified

the existing value is used. The percentage deviation shows in the secondary display.

DELTA?

Returns the Delta % value. The syntax of the response is:

where <ASCII data> is an 18-character string divided into two fields (value followed by %) exactly

as for the standard READ? response; see that command section for details.

If Delta% is greater than 999.99% the response value will be <OVFLOW>; if the Delta% function

is not running the response value will be zero.

LIMITS [<nrf>, <nrf>]

Selects the Limits function and optionally sets the limits (LO, HI); if no reference is specified the

existing value is used. PASS, LO or HI is shown in the secondary display.

LIMITS?

Returns the result of the latest Limits comparison. The syntax of the response is:

where <ASCII data> is either PASS, LOW, HIGH, or OFF.

PASS indicates that the reading was between or equal to one (or both) of the limits.

LOW indicates that the reading was less than the LO set limit.

HIGH indicates that the reading was above the HI set limit.

OFF indicates that the Limits function was not running.

MMON

Starts the Min-Max recording mode, initially setting both Min and Max to the same value. If Min-

Max mode is already running, Min and Max are reset to the same value and recording starts

again.

MM?

Returns the recorded Min and Max values. The syntax of the response is:

where each <ASCII data> is an 18-character string divided into two fields (value followed by

units) exactly as for the standard READ? response; see that command section for details. The

two 18-character strings are separated by 2 spaces.

AXB [<nrf>, <nrf>]

Starts the Ax+b scaling function and optionally sets the A and b parameters; if A and b are not

sent the existing values are used.
