7.3.1.1 Reading Temperature

The most recent temperaturemeasurement can be read using the following

command:

T<EOS> reads the most recent measurement

The syntax of the response isas follows:

t:_nnnn.nnn_u

or

t:_nnnn.nnn_u_hh:mm:ss

The _’srepresent space characters. The n’s represent the digits of the measure-

ment value.If fewer digits are needed the leading positio ns arefilled with space

characters. The u represents the unit which is either ‘C’, ‘F’, ‘K’, or ‘O’(for

ohms). The timestamp appears if this option is enabled (see Section 7.3.1.4 be-

low).The time appears in 24-hour format with two digits each for hours, min-

utes, and seconds.

The following SCPI compatible command can also be used to return the most

recent measurement butwithout the label and unit.

FETC?<EOS> or

FETCH?<EOS> returns the value of the most recent measurement
