8.4  Electro-mechanical problems

Table 11 provides troubleshooting guidance for electro-mechanical issues.

NOTE: 

See Appendix G for a system schematic.

NOTE: 

For instructions on contacting Hot-Line Technical Service, see “Contacting Advanced Instruments” on page 5.

Symptom

Possible cause

Suggested action

No power, or abrupt loss of 
power (no display)

Power availability

Temporarily unplug the power cord from its wall outlet and 
replace it with a known working lamp or other appliance. If no 
power is present, have the power restored.

Power connection to grid

Unplug the power cord from the power cord socket. Measure the 
AC voltage supplied at the end of the cord that will be connected 
to the product.

Power connection to product

Make sure the power cord is firmly plugged into the socket on the 
back of the product.

Blown fuse

Unplug the power cord from the power entry module. Use a small 
screwdriver to pry out the fuse holder. Visually check the two 5 
mm x 20 mm fuses for a blown fuse. If there is any doubt, test the 
fuses with a continuity checker or ohmmeter, or simply replace 
them (see Replacement Procedure 133072PM in Appendix I). 
Also check the values marked on the fuses to make sure that they 
are the correct rating for the product.
If a fuse was blown and a replacement fuse 

also

 blows, contact 

Advanced Instrument Hot-Line Technical Service for assistance.

Power supply

Check for 12 V DC/16 Amp on the power distribution board.

Circuit board connections

Check that all connectors on the circuit board are properly 
connected and that there are no damaged wires. Firmly insert all 
connectors. If wiring is damaged, contact Advanced Instrument 
Hot-Line Technical Service for assistance.

Unable to identify cause

Contact Advanced Instrument Hot-Line Technical Service for 
assistance.

Sample probe open error

Sample probe component failed

 Replace sample probe (p/n 133060R)

Block probe open error

Block probe component failed

Replace block probe (p/n 133058R)
