Table 4-8. Command and Query Reference (cont)
SCALE_MB? Mx+B Scaling Values Query
Return the M and B scaling values for the indicated channel.
SCALE_MB? <channel>
<channel> = (0 .. 20)
If the channel number given is invalid, an Execution Error is generated.
Remember that Mx+B scaling values are automatically reset to 1 (M) and
0 (B) when the function for that channel is changed.
This command returns three values. The first two are the M and B values
for the channel indicated, even when M=1 and B=0 or the function is
defined as OFF. These first two values are returned in M and B order
and in scientific notation format with five digits of resolution. The third
value returned indicates the Mx+B resultant display range.
SCAN Enable/Disable Scanning
This command performs the same function as Q on the front panel.
SCAN 1 Enable scanning.
SCAN 0 Disable scanning (any scan in progress is completed first.)
If there are no configured channels (all are defined as OFF) or values
other than 0 or 1 are given, an Execution Error is generated.
The MON and SCAN commands work in conjunction with the front panel
controls. The Monitor and Scan functions can be enabled or disabled
from either the front panel or the computer interface. The most recently
specified monitor channel (from front panel or computer interface)
becomes the one channel monitored.
Front panel
Q and M buttons work only when the lockout state is
LOCS.
SCAN? Return scan status. If a scan is in progress, a "1" is returned at the end of
the scan. (A response delay may occur if SCAN? is sent early in a scan.)
This feature allows synchronization for other commands that would not
be recognized if received during a scan. For example, SCAN?;*TRG
could be used to trigger a new scan after completion of the current scan.
Otherwise, a *TRG command sent while a scan is in progress would be
discarded. If a scan is not in progress, a "0" is returned immediately.
SCAN_TIME? Time of Scan
Returns values indicating the time and date at start of last scan. Uses the
same format and order as the TIME_DATE? query. The data is returned
in the following order: Hours (0-23), Minutes (0-59), Seconds (0-59),
Month (1-12), Date (1-31), Year (0-99). Setting of time does not include
seconds, but retrieval of time does.
TEMP_CONFIG Temperature Configuration
Set temperature configuration using the given value. Successful
execution of this command clears all Review array
values (all channels.)
TEMP_CONFIG <value>
<value> = encoded bit fields
