Operating Procedures
3.8 – Normal Function Test Procedures
This section involves “normal function” test proce dures, and includes 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 DC Voltage Reading at DC Receptacle Terminals
To verify that the power cells are fully charged, set the digital multimeter to measure dc voltage. As shown in
Figure 3.8.2., place the positive probe (red) on the positive post of the DC Output Connector and the negative
probe on the negative post. The multimeter display should read approximately 14.25 Vdc (± 0.5 Vdc) when
power cells are fully charged and the unit is plugged into an appropriate ac power source. When the unit is
not plugged into an ac power source, the multimeter display should read approximately 12.75 Vdc.
