AC Power and Grounding Requirements
3-4Strata DK I&M    5/99
AC Power and Grounding Requirements
The DK40i requires a solid earth ground for proper operation. 
The AC power cord contains a conductor 
for the “third-wire ground” provided by 
the commercial power outlet. The third-
wire ground should be the only ground 
necessary for the DK40i; this ground 
must originate at the buildings main 
power distribution panel and have a solid 
connection to earth ground. (See Figure 
3-3.)...

6.Set the meter to the “OHMS/Rx1” scale. Place one probe on the ground terminal, and the other 
probe on the terminal that produced a reading of zero volts. The reading should be less than 1 
ohm.
CAUTION!If the reading is more than one ohm, then the outlet is not adequately grounded. 
If the above tests show the outlet AC voltage is not in range or is not properly 
grounded, the condition should be corrected (per...
