:ELEMents? Query elements in data string
This command is used to specify the elements to be included in the data
string for each measurement conversion. You can specify from one to all
three elements. Each element in the list must be separated by a comma (,).
These elements, shown in Figure 5-1, are explained as follows:
READing: Instrument reading. The resolution of this reading tracks the dis-
play resolution of the instrument. An overflow reading reads as +9.9e37 with
no units.
CHANnel: Corresponds the instrument reading to the channel number of a
switching card. If not scanning, the channel number is 0.
UNITs: This element attaches the function unit to the reading, and the chan-
nel unit (internal or external) to the channel number. An internal channel re-
fers to an internally installed switching card channel, while an external
channel refers to the channel for an external switch system. This element is
not available for the binary formats.
The ASCII format shown in Figure 5-1 shows the byte order of the data
string. Keep in mind that the byte order can only be reversed for the binary
formats.
When using this command to add an element, you must include all elements
that you want in the format. For example, if the reading is already specified
and you want to add the channel, you must include the READing parameter:
:form:elem chan, read
Data elements for the item list can be listed in any order, but are always sent
in the order shown in Figure 5-1.
