Status *
* If tolerance A is lower than the inserted tolerance B (internal diameter measurements) then the
signs > and < are reversed.
If one of the Min/Max/Delta functions is activated, the sign corresponds to the extrema measured
since the last reset (the reject sign takes precedence over the rerun sign which itself has prec-
edence over the OK tolerance sign). See also remote controls TOLM ? and TOLS ?
6. Min/Max/Delta function
The module can be configured to search for minimum and maximum values (see remote com-
mands MIN, MAX, DEL, NOR). Searching for extrema is only active when one of the 3 modes
MIN, MAX or DEL is active. The ? remote command then returns the selected extrema. When
one of the 3 modes is active the MIN?, MAX? and DEL? commands return the desired extrema.

Customised read out
7.1. Number of read/sec
The module can be configured for a customised probe position reading speed (see the remote
commands RES7 or RES8). When one of these 2 resolutions is activated the user may change
the number of measurements per second (SUM remote command) and configure the filtering
time constant for the values read (PF remote command). SUM represents the number of internal
conversions required to obtain a measurement (average value). When low SUM and PF values are
programmed simultaneously the values read may be modified by a higher level of noise. The usual
values for the predefined SUM and PF depending on the resolutions predefined in the module are
given for reference in the following table:
SUM [-]
RES1
14..18
RES2
6..10
RES7 / RES8
* For the highest number of measurements per second also select a high transmission speed
(see BAUD) and if necessary disable one or more of the probes (see ACHA).
7.2. Synchronization of readings probes positions (D304y only)
By default, the position of each probe is read independently of the one of the other probes. For
some applications (dynamic measurement of the difference in position between two probes),
it is necessary to synchronize the readings of a D304y module (see remote command SYNF).
