Description
REL
Relative enabled for selected DMM function.
REM
Instrument in bus remote mode or web interface control mode (all interfaces, LAN,
GPIB, or USB).
SRQ
Service request over GPIB.
TALK
Instrument addressed to talk over GPIB bus.
TRIG
ON when the front panel has requested a reading from the DMM. OFF when the
reading is finished.
The bottom left line of the display (4) contains the DMM attribute symbols. The
symbols that appear are dependent on whether the attribute exists for the
selected function. The following table indicates the DMM attribute symbols that
may appear on the front panel. If the symbol has a value associated with it, the
third column in the table indicates the value definition.
