INTVL?

LAST?

Table 4-5. Command and Query Reference (cont)

Set Scan Interval

Set scan interval time.

INTVL <hours>,<minutes>,<seconds>

<hours> = (0 .. 9) <minutes> = (0 .. 99) <seconds> = (0 .. 99)

An Execution Error is generated if values outside the specified ranges are used or if the instrument is scanning.

Example: INTVL 1,30,0 [Set the interval time to 1 hour, 30 minutes and 0 seconds.]

Scan Interval Query

Return scan interval time. Returns the scan interval time in the format <hours>,<minutes>,<seconds>.

Example INTVL? returns 0,0,0 [The interval time is 0 hours, 0 minutes, and 0 seconds (continuous scanning).]

Channel’s Last Scan Value

Returns the last measured value(s) for the scan in progress or the last completed scan.

LAST?<channel>

<channel> = 0, 1, 2, ... 20

Returns last measurement values for either the indicated channel, or for all defined channels if the <channel> field is left blank. 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 by REVIEW_CLR, or by changing any parameter on any channel. The returned value is a signed number with decimal point and exponent. For slow scanning rate, 5 digits are returned (+/-XX.XXXE+/-N); for fast scanning rate, 4 digits are returned (+/-XX.XXE+/-N). The channel range setting determines placement of the decimal point. A return of +001.00E+9 indicates an overload (OL) condition; a return of +009.00E+9 indicates an open thermocouple (otc) condition. If no channel specification is made, all the last values of the scanned channels are returned, each separated by a comma.

Example: LAST? 1 returns +0074.4E+0 [The last scanned value of channel 1 is 74.4.]

Example: LAST? returns +060.14E+0,+013.84E+0,+009.00E+9 [Three channels were scanned. The first channel had a last reading of 60.14; the second channel had a last reading of 13.84; the third channel reading indicates an open thermocouple (RATE 0 and FORMAT 1 are asserted).]
