Fluke PM6685 Outdoor Timer User Manual


 
This is the value that will determine the
output voltage; .00 will give 0 V and .99
will give 5 V. This means that the reading
will give:
.67890*5=3.3945 V.
This is ouput as 3.38 V due to the 0.02 V
resolution of the analog output.
n
Resolution
The analog output range is 0 to5Vin
250 steps, so one step is 0.02 V. If the
scaling factor is 1, one such step is taken
each time the display changes with
X.004, and if the scaling factor is 4, one
step is taken each time the display
changes with X.001.
The X in the above paragraph can be any
digit and does not influence the output
voltage. If the display changes from
0.996 to 1.000, the voltage drops from
4.98 V to 0V. If the display value in
-
creases further, the output voltage starts
to increase again; see .
