All Herrmidifier 6000
manufactured under strict quality control and are
subjected to a complete operational test. All circuit board
adjustments are made at the factory and should not be

TEST POINTS
Each circuit board (See Figure 12) features three test
points to aid in the troubleshooting process.
these test points works on a 0-4 VDC scale. "0 VDC" =
0%. "4 VDC" = 100%. All readings are between the test
point and ground (Molex J1, terminal 11 [far right of
molex connector, hours wire #11]).
Test Point #1:
Provides exact reading of drain threshold setting.
Test Point #2:
Provides circuit board reference voltage. Should always
read 4 VDC +/-2%.
Test Point #3:
Provides actual percentage of output. For example, a
unit running at 80% of maximum output would have a
Test Point #3 to ground reading of 3.2 VDC.
