Table 4-8. Command and Query Reference (cont)
MIN? Channel’s Minimum Value
Returns minimum value(s) for channels measured in the most recent
scan. The value returned represents data from the most recent scan. The
most recent scan is the scan in progress or, if scanning is not in
progress, the last completed scan.
MIN? <channel>
<channel> = (0 .. 20)
If the channel specification field is left blank, values for all defined
channels are returned. Channels defined as OFF are not included. An
Execution Error results if a request is made for a channel defined as
OFF, the channel specified is invalid, the channel specified has been set
up but not yet measured, or Review array values have been cleared.
The response is a signed number with decimal point and exponent. For
slow scanning rate, 5 digits are returned (+/-XX.XXXE+/-X); for fast
scanning rate, 4 digits are returned (+/-XX.XXE+/-X). The range setting
determines placement of the decimal point.
For minimum values of all defined channels (no channel specification
made), undefined (OFF) channels are not included. For each defined
channel, a separate signed number with decimal point and exponent is
returned. Commas separate numbers for different channels, and no
blank spaces are included.
MON Enable/Disable Monitoring
This command performs the same function as M on the front panel.
MON 1,<channel> Enables monitoring of given channel (if monitoring
is disabled). Changes monitored channel (if monitoring is already
enabled).
MON 0 Disables monitoring.
The <channel> parameter can be 0 through 20. A command error is
generated if no <channel> parameter is given when enabling monitoring.
If the channel to be monitored is invalid or defined as OFF, or if 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.
MON_CHAN? Monitor Channel Number
This query asks for the number of the presently defined monitor channel.
If monitoring is not active, an Execution Error is generated.
MON_VAL? Monitor Channel Value
This query asks for a measurement on the monitor channel. If monitoring
is not active, an Execution Error results.
