4. A000 or A00F will appear according to the present scaled conversion data
in approximately 0.5 seconds.
5. While CC00 is set to the output word, the A000 or A00F and the present
scaled conversion data will be repeatedly displayed alternately at approxi-
mately 0.5-s intervals.
6. Set 0000 to the output word again to cancel reading the present scaled
conversion data in binary.

The CQM1-LSE02 has a monitor output function.
The CQM1-LSE02 can be in scaled conversion data monitor mode or set data
D/A output mode, either of which can be selected with the operation mode A
set command.
The CQM1-LSE02 in scaled conversion data monitor mode does not require
special operation settings. Refer to the following to operate the CQM1-LSE02
in set data D/A output mode.
In this mode, the monitor output terminal of the CQM1-LSE02 will have volt-
age output corresponding to the scaled conversion data which is written in the
output word allocated to the Unit. Therefore, the ladder program enables the
CQM1-LSE02 to output an analog input signal as a desired voltage value.
Refer to the following table to set signed binary data to use the monitor output
function.
Set output binary data
2710 (10000) min.
270F (9999)
0000
D8F1 (–9999)
D8F0 (–10000) max.
There is no setting range restriction except for the following cases.
If the signed binary data of the CQM1-LSE02 output word is the same as or
less than D8F0 (–10000), –9.999 V will be output from the monitor output ter-
minal. If the signed binary data of the CQM1-LSE02 output word is the same
as or larger than 2710 (10000), 9.999 V will be output from the monitor output
terminal.
Note When obtaining the value to be set to the output word through calculation
using the ladder program, be careful not to use the computed result of "C000
to CFFF." Even when the Unit is used in the set data D/A output mode, if
"C000 to CFFF" is set to the output word, it is treated as a command.
In this mode, analog input is converted into digital data and then converted
into analog output. Therefore, the obtained analog output is not highly precise.
