Current Output Page
The current output is assigned to the ammonia concentration but is only operative if the relevant output modules are fitted – see
Fig. 2.4.
Page header.
Advance to next parameter.
Output 1 Calibration Hold
Current Output 1 can be held during calibration, if required. Select 'YES' or 'NO'.
Store.
Advance to next parameter.
Output 1 Law
Current Output 1 can be either logarithmic or linear. Select 'Log' or 'Lin'.
Store.
Advance to next parameter.
Output 1 Full Scale
Current Output 1 full scale range: 0.5 to 2000 mg l
–1
ammonia, i.e. minimum span
is 1 decade.
Set the required concentration value for Current Output 1 full scale.
Store.
Advance to next parameter.
Output 1 Zero
Set the required concentration value for Current Output 1 zero.
Note.
If the output 1 Law is linear (Lin), this parameter is omitted and the zero
current output is automatically set to '0'.
Store.
Advance to next parameter.
