4.2 ANALOG OUTPUT
The user can request for a specific output current or voltage range or there are a number of
standard analog output ranges the user can select from, which are listed below. The analog
output the user selects is scaled to the user’s hydrogen range of interest. All of this is initially
set at the factory per customer specification at the time of order.
Below is the table for standard analog output current ranges:
Current Analog Output Range Power-On Self Diagnostic Error
4 mA to 20 mA 2 mA 3 mA
0 mA to 20 mA 0 mA 20 mA
