4.1Troubleshooting Problems, Possible Causes,

and Solutions

In the event that the instrument appears to function abnormally, this section may help to find and solve the problem. Several possible problem conditions are described along with likely causes and solutions. If a problem arises, please read this section carefully and attempt to understand and solve the problem. If the problem cannot otherwise be solved, contact an Authorized Service Center (see Section 1.3). Be sure to have the model number, serial number, and voltage of your instrument available.

Problem

Possible Causes and Solutions

 

 

Incorrect temperature Incorrect R0, ALPHA, and DELTA parameters. Find the values for R0, AL-

readingPHA, and DELTA on the Report of Calibration that was shipped with the instru- ment (or from subsequent calibrations of the instrument). Reprogram the parameters into the 2200 memory (see the 2200 User’s Guide). Allow the in- strument to stabilize and verify the accuracy of the temperature reading.

 

Controller locked up. The controller may have locked up due to a power

 

surge or other aberration. Initialize the system by performing the Factory Reset

 

Sequence.

 

Factory Reset Sequence. Hold the SET and EXIT buttons down at the same

 

time while powering up the instrument. After the instrument displays -init-,

 

release the buttons. The display shows -init-, then displays 9132, and then

 

displays the firmware version. After performing the master reset sequence, all

 

of the configuration parameters are reset to their default values. Reprogram the

 

R0, ALPHA, and DELTA parameters into the Model 9132 memory (see Section

 

, Calibration Parameters) and any other applicable configuration parameters.

 

Allow the instrument to stabilize and verify the accuracy of the temperature

 

reading.

 

 

Blank display after

Blown fuse. A fuse may have blown due to a power surge or failure of a com-

mains power applied

ponent. Replace the fuse once. If the fuse blows a second time, it is likely

 

caused by the failure of a component. Always replace the fuse with one of the

 

same rating, voltage, and type. Never replace the fuse with one of a higher cur-

 

rent rating.

 

 

The Instrument heats or cools too quickly or too slowly

Incorrect scan and scan rate settings. The scan and scan rate settings may be set to unwanted values. Check the Scan and Scan Rate settings. The scan may be off (if the unit seems to be responding too quickly). The scan may be on with the Scan Rate set low (if unit seems to be responding too slowly).
