Operating Procedures
3.8 – Normal Function Test Procedures
This section deals with “normal function” test proce dures, and includes all steps necessary to ensure that
the unit is operating within specified para meters prior to use. A digital multimeter (an example is shown in
Figure 3.8.1) capable of measuring DC and AC voltage and resistance will be required to perform some of
the tests. These functional test procedures should become routine.

Check Unit for Evidence of Damage
Check for dents, punctures, case distortion or misalignment, and cracked or loose connec tors. If no damage
is evident, proceed to the next step. If damage is evident, contact Tesla™ Industries, Inc.
Check Unit Internal Resistance (Test for Shorts)
NOTE
!
Unit should be disconnected from any ac power sources prior to testing.
It is essential to test for shorts to detect any problems with the unit. To do so, you will need to set your
multimeter to measure Ω or “resistance.” You can test to see if both DC Output terminals are isolated from
the chassis ground and line ground in the following steps.
1. Verifying Connection between the Chassis and the AC Input Ground.
Touch the red lead of the multimeter to an exposed metal area on the chassis
(e.g. one of the connector fastening bolts). Next, touch the black lead of the
multimeter to the ground pin of the AC Input Receptacle (shown in Figure
3.8.2). The multimeter should read nearly zero ohms. If this is not the case,
please contact Tesla™ for further instructions.
2. Testing between the Chassis Ground and the AC Input Neutral Pin.
Touch the red lead of the multimeter to an exposed metal area on the chassis
(e.g. one of the connector fastening bolts). Next, touch the black lead of the
multimeter to the neutral pin of the AC Input Receptacle (shown in Figure
3.8.3). The multimeter should read open circuit. If this is not the case, please
contact Tesla™ for further instructions.
