not implemented 02DX will be sent (helpful when looking
for errors in the control program). The following informa-
tions will be issued immediately after any keyboard ope-
ration or in case of, e.g., result memory full, auto range:
00XX, 0100, 0101, 0111-7, 0140, 0147, 0148, 0182-5, 0190,
0191, 0198, 01C1, 01C2.
– Parameter 5 turns the continuous status function on. The
auto status function, if active, will be disabled. After each
result obtained the actual function and range will be trans-
mitted in the format 00XX, followed by the transmission of
the measurement time in the format 011X. Any information
of group 1 caused by a status change of the instrument will
be stored and transmitted in place of the measurement
time synchronously with the next result. In case there will
be more than one group 1 information caused by a keyboard
operation or by the instrument's control program (e.g. result
memory full, auto range) within the same measurement cyc-
le those informations will overwrite each other. Only the last
information will be transmitted with the next result. Range
or function changes via the keyboard may cause several
group 1 informations. Hence only the status of the auto
range function will be transmitted, messages concerning
changes of the functions Max/Min or the result memory will
be suppressed. (this does not apply to commands received
via the interface). These status changes may be taken from
the following table:
Max/Min
Change of range restart
Change of function off
Full information about the instrument status may be recei-
ved by the command 02C2.
The auto status function has this format:
+/-X.XXXXXX Result with sign
0XX Function and range
1XX Group 1 information
The following group 1 informations are transmitted: 0100,
0101, 0111-7, 0120-4, 0140-4, 0140-143, 0147, 0148, 0184-5,
0190, 0191, 0198, 01C0-1C2.
If buffer operation is active (01A1) the auto status function
will remain active, function, range, and group 1 information
will be be stored in the ring buffer together with the results.
The description of the auto status function remains valid in
full. Any commands of groups 0 and 1 will be echoed after
their execution. These echoes may be used for handshaking
obviating any waiting times.
Function F (data) provides instrument information.
– Parameter 0 issues the 6 digit software revision number
XXXXXX.
– Parameter 1 issues the last calibration date in the format
DDMMYY
- Parameter 2 issues the serial number.
- Parameter 3 issues the milliohms of the cable resistance
compensation in case of 2-wire PT100- (PT1000-) tempe-
rature measurements.
