The single LED (dual color) has a flash sequence that alllows you to determine PP02..... Solid Green is "on setpoint" and it then flashes green "flash..... flash" if you are 0.1 high and the same in red "flash...... flash....." if you are 0.1 low. double flash green "flash flash...... flash flash........" = 0.2 high and doubld flash "flash flash....... flash flash........" in red is 0.2 low. Continue the number of flashes for the PP02 high and low in 0.1 increments. Works great and the circuit board can be used single, double, or triple cell.
Bottom line is that you know the PP02 in 0.1 ATMA increments in relationship to desired setpoint.

And the colors of the sea blind your eyes with trembling mermaids, For the sparkling waves are calling you to kiss their white-laced lips.
And you see a girls brown body dancing through the turquoise, And her footprints make you follow where the sky loves the sea.
And when your fingers find her, she drowns you in her body, Carving deep blue ripples in the tissues of your mind...... |
