5. TROUBLESHOOTING

Many thermometer operational parameters can be tested for proper operation before

the unit is taken apart and without needing any tools. Refer to

Operational

Characteristics

on page 1-1 and in particular to the

Setup

and

Biotech Mode

sections for guidance on preliminary checks.

If the trouble seems to be calibration related, refer to

Calibration Testing

page 3-1.

If these sections do not prove useful in resolving the problem and you are sure that

the instrument is not performing properly, the following sections should guide you

through the debugging process given the proper tools and equipment.

Error Codes

Error codes are divided into four classes:

Probe Probe errors are generated by the probe or the probe connector and are

not errors generated by the thermometer. They do require that

temperature measuring be inhibited until the error is cleared. There is no

limit to the number of times a probe error can occur. All probe problems

are considered by the thermometer to be recoverable. When a probe error

occurs, the probe icon is displayed.

Ambient

Temperature

Ambient Temperature errors occur when the ambient probe temperature is

above 104.0° F or below 60.8° F. During an ambient temperature error, the

display shows an ”A” with either the up or down arrow icon flashing.

Dead Battery Dead Battery error occurs when the instrument detects a battery voltage of

3.0 volts or less. The battery icon is displayed without flashing when this

error occurs.

Instrument

Circuitry

Instrument Circuitry errors are generated from internal test failures and can

be recoverable or non-recoverable. Error code numbers are only available

in Biotech mode.

•

Recoverable errors require that temperature measuring be

inhibited until the error is cleared. After displaying the error |X|

icon, the instrument will shut itself off and store the error code in

memory.

•

Non-recoverable errors are generated from internal ROM and

RAM test failures. The error code will be stored in memory and

the LCD will disply the error |X| Instrument Malfunction icon.The

only way to recover from a ROM or RAM error is to reset the

electronics by removing the batteries.

Note:

Error codes E0.1, E0.2, E0.3, can sometimes be caused by a faulty probe. It is

advisable to remove the probe completely from the instrument and check its

functionality as described in the

Operational Characteristics

section before assuming

an instrument problem instead of a probe problem. If another probe is available, this

can prove useful in tracking down the source of the problem.
