MAX? Channel's Maximum Value
Returns the maximum value(s) measured since the review array was last cleared.
Channel's Maximum Value
MAX?
Returns maximum 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 return 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 maximum values of the scanned channels are returned,
each separated by a comma.
Example: MAX? 1 returns +022.34E+0 [The maximum scanned value of channel 1 is
22.34.]
Example: MAX? returns +009.00E+9,+890.22E+0,+230.96E-3 [Three channels were
scanned. The first channel shows an open thermocouple; the second channel had a
maximum reading of 890.22; the third channel had a maximum reading of 0.230
(RATE 0 and FORMAT 1 are asserted).]
Memory Card Status
MCARD?
Returns the memory card status as an encoded integer number from a binary
number using bits 0 to 4.
Bit 0 - Card changed; remaining bits differ from the last query
Bit 1 - A card is present in the unit
Bit 2 - Card is write protected
Bit 3, 4 - Battery status of last inserted card, as below:
BIT 4
0
0
1
1
Example: MCARD? returns 7 [The memory card status is 00111 (decimal 7),
meaning the card changed since the last query, a card is in the unit, the card is write
protected, and battery is operational.]
