Operating Procedures
3.7 – Normal Function Test Procedures
This section involves “normal function” test proce dures, and includes steps necessary to ensure that the
TI1000 GPU is operating within specified para meters prior to use. A digital multimeter (an example is shown
in Figure 3.7.1) 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. Turn on the DC Circuit Breaker before testing. As shown
in Figure 3.7.2., place the positive probe (red) on the positive post (C) of the
DC Output Connector and the negative probe on the negative post (A). The
multimeter display should read approximately 28.5 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 25.5 Vdc.
