10.Troubleshooting Guide

Symptom: Power on - No display activity.

Action: 1. Check for proper AC voltage at the outlet.

2.Ensure that the AC power cord connectors are firmly seated in their sockets. (at the outlet and at the instrument.)

3.Check the fuse.

a)Remove the power cord from the IEC-320 socket on the back of the instrument.

b)Pry the fuse holder out of the socket assembly by using a screwdriver in the small slot inside the IEC-320 socket.

c)Check the fuse that is in the fuse clamp. If it is found to be defective, remove it from the clamp. Press the spare fuse case out of the fuse holder body and insert the spare fuse into the fuse clamp.

d)Reassemble the power inlet assembly by reversing the above directions.

e)Check the power supply for proper operation

4.Check the AC/PCB connection.

a)Remove the front panel by removing the bezel and four phillips head screws. (Disconnect AC power prior to removal of the front panel.)

b)Slide the display board and the main PCB out of the case.

c)Verify that the white AC connector is firmly seated over all five pins of P4.

5.Check the display board connection.

a)Verify that the 13 pin SIP connector is firmly seated over all 13 pins of P3 and that the red strip is towards the rear of the case.

b)Verify that the 5 pin ribbon connector is firmly seated over all 5 pins of P2 and that the silver side is toward the case.

6.Consult the factory.

Symptom: Rapidly running, random digits on display

Action: 1. Consult the factory.

Symptom: Display shows decimal point and minus sign only

Action: 1. Check microprocessor.

a)Remove the front panel.

b)Verify that the microprocessor is properly seated in the chip carrier.

2.Consult the factory.
