precise format. There are four principal data types;
Numeric Parameters
are decimal numbers which include an optional sign, mantissa, decimal point
and exponent. Engineering suffix units are not accepted.
Discrete Parameters
have limited values e.g. SINGle, INFinite, and like command keywords they can
have long and short forms, upper and lower case.
Boolean Parameters
have a single binary value. The controller can send OFF or 0, ON or 1, but the
instrument response is always 0 or 1.
String Parameters
contain ASCII characters which are placed between a pair of double quotation
marks, i.e. “ “.
Input Data Format
Numeric data sent to the instrument should be in Ohms or degrees unless stated otherwise. The value
can be in any standard scientific format.
e.g.
3KOHM can be sent as:
3000, 3E3, 3.000E3, 0.3E4 etc.
The units are not sent.

<cr> = carriage return character
<lf> = linefeed character
Note: In IEEE mode the EOI line is also asserted with the transmission of the <lf> terminator.
Measurement queries always return values expressed in Ohms or Degrees, but the units are omitted.
Resistance values are returned with engineering exponents reflecting the resolution and units displayed
on the LCD screen.
