Table 4-5. Command and Query Reference (cont)
SCAN? Scan Query
Returns the scanning status, as selected with the SCAN command.
0 Scanning is disabled
1 Scanning is enabled
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, where just 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).
Example: SCAN_TIME? returns 7,56,50,7,21,94 [The start of the last scan was at
0700 hours, 56 minutes, 50 seconds, on July 21, 1994.]

*SRE? Service Request Enable Query
(See front of table.)
*STB? Read Status Byte Query

TEMP_CONFIG
Temperature Configuration
Set temperature configuration using the given value. Changing the temperature
configuration also clears the Review array, and ALARM OUTPUTS and DITGITAL
I/O lines.
TEMP_CONFIG <value>
<value> = 0. 1, 2 , 3
Selects the temperature scale (°C or °F) and enables or disables thermocouple
detection. When thermocouple detection is enabled and an open thermocouple is
detected, the monitor display will show "otc" and the measurement return is
+009.00E+9. When thermocouple detection is disabled and an open thermocouple is
detected, the monitor display will show "OL" and the measurement return is -
001.00E+9. These settings affect every channel; they cannot be set for each
channel individually. The command is entered when the instrument is not scanning.
Select the desired <value> from the table below.
Value Meaning
0 OTC Disable and °C
1 OTC Disable and °F
2 OTC Enable and °C
3 OTC Enable and °F
Example: TEMP_CONFIG 3 [Measure temperature in °F and enable "otc" detection.]
