NOTES
The GPIB command error and GPIB execution error are
always enclosed within exclamation marks (!). If no errors
have been produced since the last ERRLST was read,
the ERRLST will end with '!!!'.
When read for the first time after startup, a sensor may be
reported as not fitted even though it is. This is because
the error condition of a sensor used in a channel configu
-
ration was recorded before the sensor initialization was
completed.
If a sensor is not used in a channel configuration, it will be
reported as Zeroed, although it may not have been. If the
sensor is then used in a channel configuration, it’s zero
status will be correctly reported.

GPIB SETUP
Syntax:
FAST <state>
state:
ON or OFF
Remarks:
This command allows the system, for speed purposes, to send the present
system readings directly to the output, with no buffering at all (obeying the
rules sent earlier when talk addressed). GPIB 488.2 rules specify that data
should only be given after a request. FAST mode allows data to be read
without requesting it first (like the HP 437/8). The following conditions and
restrictions apply:
a. REMOTE is written across the screen, and no screen updates are done.
b. Sensor data for a single sensor only can be output from display channel
1, according to the following rules:
If the input configuration for display channel 1 is set to either OFF or EXT
VOLTS, it is set to ‘A’ and sensor A data is output if a sensor is con
-
nected to input A.
If the input configuration for display channel 1 is set to a sensor combina
-
tion (A-B, A/B, etc.), the configuration is left as is but only the sensor A
data is output.
If the input configuration of display channel 1 is set to ‘B’, sensor B data
is output.
c. Output from display channel 2 is set to OFF.
d. Output is in dB only.
