• Pencil Test
- Pencil Rx Test
When performing the Pencil Rx Test, no probes or jig are connected to the system.
This test is performed to check the receive functions. During this test, signals are transmitted
through the circuitry. The received frequency should match the transmitted test frequency, as
shown in the Test report.
For test procedure instructions, see the Pencil Rx Test section, page 7-83 .
7-2-4-3 Monitoring Tests
7-2-4-3-1 Full System Monitoring Test
The Full System Monitoring Test performs a full sequence of all monitoring tests (as described below).
For test procedure instructions, see the Full System Monitoring Test section, page 7-86 .
7-2-4-3-2 Fixed Voltages Test
The Fixed Voltages Test is used to check the Power Supply unit and to ensure that voltages are within
the pre-defined limits.
For test procedure instructions, see the Fixed Voltages Test section, page 7-93 .
7-2-4-3-3 Temperatures Test
The Temperatures Test is used to check the temperature of the Front End and the Back End. The test
reads all the temperature sensors in the system to ensure that the system is operating within the
pre-defined temperature limits and that there is no overheating of any components.
For test procedure instructions, see the Temperatures Test section, page 7-96 .
7-2-4-3-4 Fans Speed Test
The Fans Speed Monitoring Test is used to check that the Fan Controller is fully operational and that
all five fans operate simultaneously (at the pre-defined speed) to maintain proper cooling and the
optimum operating temperature of all Vivid q N system components.
For test procedure instructions, see the Fans Speed Test section, page 7-99 .
7-2-4-3-5 Battery Parameters Test
The Battery Parameters Test is used to check the battery status with regard to the following:
• Battery capacity
• Charging voltage being supplied to the battery (or the voltage being supplied by the battery)
• Source of the power being provided to the system (i.e. external power via the AC/DC or via the
battery [indicating the battery is either being charged or discharged]).
For test procedure instructions, see the
Battery Parameters Test section, page 7-102 .
7-2-4-3-6 Tx Voltages Test
The TX Voltages Test is used to test the transmit part of the power supply to make sure that the
Tx voltage is within expected values.
For test procedure instructions, see the Tx Voltages Test section, page 7-105 .
