SCAN

SCAN?

SCAN_TIME?

TEMP_CONFIG

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.

Enable/Disable Scanning

This command performs the same function as Qon 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 Qand Mbuttons work only when the lockout state is LOCS.

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.

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.

Temperature Configuration

Set temperature configuration using the given value. Successful execution of this command clears all Review array

values (all channels.)

TEMP_CONFIG <value>
