Table 4-5. 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
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 channel 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
display range. The Mx+B scaling values are automatically reset to 1 (M) and 0 (B)
when the function for that channel is changed.
The range code for the display <range> is shown below:
Range Display Max B

SCAN
Enable/Disable Scanning
This command performs the same function as
Q
on the front panel.
SCAN 1 Enable scanning.
SCAN 0 Disable scanning
If SCAN 0 is set during the measurement interval of the scan, the measurement
portion is completed. If SCAN 0 is set during the countdown interval of the scan, the
scan is immediately terminated.
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 “local without
lockout” (see the LOCS command)..
