Serial Interface
* When operating in maximum hold mode, returned
value corresponds to MAX HOLD value.
Same applies to peak hold mode.
When this command is received while there is no
display indication, output will be p1 to p4 = 0000.
DOF n Output instantaneous value every 0.1 seconds in non-pro-
tocol mode
n = 0 Instantaneous value output OFF
n = 1 Instantaneous value output ON
Data will be output every 0.1 seconds. When DOF 0 is
received, non-protocol mode output is terminated.
For information on output data format, see section on
"DOD?".
DOF communication format
Note
Because this unit supports only half-duplex commu-
nication, it cannot receive and send data at the same
time. When sending the DOF 0 command to the unit,
the computer must use timing which ensures that the
command does not collide with the instantaneous
value data that are being output by the unit.
