6.2.6 Parameter
The valid parameters for each command, together with the related syntax, are described in the following
chapter. The parameters are separated from the command by a blank character.
Format of a resistance parameter:
A parameter which sets a resistance value or resistance measuring range can be entered in several different
formats and units.
Resistance values can be entered in integer, floating-point or exponential form. Valid units for a resistance
parameter are:
UOHM ->
Microohm
MOHM ->
Milliohm
OHM ->
Ohm
KOHM ->
Kiloohm
MAOHM->
Megaohm
If the unit is omitted, the parameter is assumed to have ohm as the unit.
Examples of valid parameters for a resistance of 123.45 ohm are:
123.45, 123.45OHM, 0,12345KOHM, 123450MOHM, 123.45E-6MAOHM.
Format of the ON/OFF parameters
The ON/OFF parameters can be replaced by numeric parameters. The 2329 always responds with numeric
values to a query form.
OFF -> 0
ON -> 1
If only an instantaneous setting is requested, this parameter can be omitted from the query form of a command.
6.2.7 End-of-command character
A line feed (nl), semicolon (;) or EOI (IEEE488.1 end or identify), together with the character sent last (EOI only
in the case of IEC bus control) indicate the end of a command.
For example, if the HP200/300 Basic "OUTPUT709;":INIT" is sent, the controller automatically appends a
<cr><nl> to the command. With other IEC bus controllers such as a National PC card, the <nl> character
might need to be entered explicitly (e.g.: ibwrt":init\n").
6.2.8 Special features of the RESISTOMAT
®
Settings cannot be modified or read while a measurement is in progress. This means that the 2329 ignores
all commands until the measurement is stopped. Exceptions here are the "ABORt" command for stopping a
measurement, the commands for status-register control ("STATus") and the IEEE488.2 commands.
6.2.9 Effects of the "FETCh?" command while a continuous
measurement is in progress
On the transmission of this command, the next available measurement value is written to the output buffer, from
where it can be fetched (see „Command with query form“ auf Seite 68). After the value has been fetched,
a new one is only written again to the output buffer the next time a "FETCH?" command is issued.
