9.3 “atest” Analog output test
To test the analog output, use atest command to force a value. The value will be forced until
the same command is fed without parameters. The valid range of test voltage / current is the
same as current analog output range.
Command:
1. without parameter: turn off test mode and print list of testing ranges
2. three parameters: range, value, correction flag. Flag 1 to use correction, 0 no correction.
Example:
atest d 5 1<cr>
Last set: 5.000000<cr><lf>
Analog output is forced into current (0 mA to 20 mA) range and analog value is forced to 5 mA,
correction is used.
To cancel the test mode, use no parameter, for example:
atest<cr>
Test mode off<cr><lf>
atest range(abcde), value(V or mA),
[useCorr (0 or 1, default=0=no)]<cr><lf>
Ranges:<cr><lf>
a) 0 .. 1 V<cr><lf>
b) 0 .. 5 V<cr><lf>
c) 0 .. 10 V<cr><lf>
d) 0 .. 20 mA<cr><lf>
e) 4 .. 20 mA<cr><lf>
x) OFF<cr><lf>
9.4 “aerr” Analog output error indication
If for some error condition the pressure can not be measured, the analog output displays the
error value.
The valid range for error value is within current range of the analog output.
Command:
1. without parameter: print list of actual value,
