CALIBRATION: Solar 7000 Color Power Supply
Revision J
Solar 7000/8000/View Patient Monitor
5-11
414993-001
Procedure
Do the following steps in the order given.
1.
Turn power switch at the rear of the monitor to OFF.
2.
Remove the four screws attaching the power supply shield. Refer to
the “Disassembly Procedure” presented in Chapter 7: “Monitor
Assembly.”
WARNING
Beware of AC line voltage at the power module.
3.
Turn the power switch at the rear of the monitor to ON.
4.
Connect the positive lead of the DMM to +5V TP1 on the low-voltage
power supply PCB. Connect the negative lead to GND at TP6.
5.
Set DMM to DC mode. 5V ±0.1V on DMM.
6.
Connect the positive lead of the DMM to +16.75V at TP2. Adjust
variable resistor R32 to +16.75V ±0.1V.
7.
Connect the positive lead of the DMM to +24V at TP3. Adjust
variable resistor R40 to +24V ±0.1V.
8.
Set the DMM to frequency counter mode by selecting the AC and HZ
button.
9.
Connect positive lead of the DMM to TP5 labelled CLK. Verify a
frequency of 60 Hz ±2 Hz.
10. Connect the positive lead of the DMM to pin 7 of +24V regulator U5.
Adjust variable resistor R51 to a frequency of 82.8 kHz ±1 kHz.
11. Connect the positive lead of the DMM to pin 7 of +5V regulator U4.
Adjust variable resistor R52 to a frequency of 86.6 kHz ±1 kHz.
Completion
This completes the low-voltage power supply PCB calibration.
•
Remove test equipment and assemble unit.
