MMON
Sequential command.
Operation complete message generated immediately after execution.
Start the MIN/MAX recording mode, initially setting both MIN and MAX values to the same reading
value. If MIN/MAX is already operating then reset the MIN and MAX values to the same reading
and restart recording.
Note that a delay of five readings is imposed between receiving this command and starting the
recording during which time the result of a MM? query will be the 'INVALID' message.
MMOFF
Sequential command.
Operation complete message generated immediately after execution.
Stop recording MIN/MAX values and exit from MIN/MAX recording mode. The recorded MIN/MAX
values will remain unchanged and can be read using the MM? command until the meter function
is changed or MIN/MAX is restarted which will cause the values to become invalid.
If MIN/MAX is not active then no action will be taken.
MM?
Sequential command.
Operation complete message generated immediately after <rmt> is sent.
Returns the recorded MIN and MAX values.
The syntax of the response is:
MIN,MAX - <ASCII data><rmt>
<ASCII data> contains two fields separated by a space:
units data
where the units field contains the units of the basic meter function and data is the formatted data
field. The basic meter function units are:
VOLTS DC
VOLTS AC
MILLIAMPS DC
MILLIAMPS AC
KOHMS
This field is fourteen characters wide between the dash and separating space.
The data field contains the MIN value followed by the MAX value, separated by a comma. Each
value is contained in eleven characters:±n.nnnnnE±n
±nnn.nnDB
±nnn.nnn%
±OVERLOAD
±OVERFLOW
Examples:
- 0.12345E-1,+0.56789E+2
+20.00DB , +100.00DB
If there are no valid MIN/MAX values then the response syntax is:
MIN,MAX - INVALID On the serial interface the response is sent immediately if in non-addressable mode, or when
addressed to talk, if in addressable mode.
Example:
MIN,MAX - VOLTS DC
+2.10000E+1, +OVERLOAD
