Fluke PM6681R, PM6685R manual Resolution, Output Subsystem

Using the Subsystems

–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.

￿Resolution

The analog output range is 0 to 5 V in 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-
