6100 Calorimeter Error List
The calorimeter will run a number of diagnostic checks upon itself and will advise the operator if it detects any
error conditions. Most of these errors and reports will be self-explanatory. The following list contains errors
that are not necessarily self-evident and suggestions for correcting the error condition.
A Misfire Condition Has Been Detected
This error will be generated in the event the total
temperature rise fails to exceed 0.5 °C after the first
minute of the post-period.
A Preperiod Timeout Has Occurred
The calorimeter has failed to establish an acceptable
initial temperature, prior to firing the bomb, within
the time allowed. Possible causes for this error are
listed below:
• A bomb leak
• Poor bucket stirring
• Metal to metal contact between the bucket and
the jacket
• Lid not tight
• Foam seal has deteriorated
• Starting bucket temperature is too low or too
high
• Unstable room temperature
A Postperiod Timeout has Occurred
The calorimeter has failed to establish an acceptable
final temperature within the time allowed. Possible
causes for this error are listed below:
• A bomb leak
• Poor bucket stirring
• Unstable room temperature
There Is A Problem With The Bucket Thermistor
Possible electrical open or short. These errors will
result if the temperature probe response is not within
the expected range. Probe substitution can be useful
in determining the cause of the problem (probe or
electronics). The valid working range of the probe
resistance is 1000 to 5000 ohms.
• Check connection to board
• Check quick disconnect between cables
• Replace probe
• Room temperature is below 10 °C (50 °F)
There Is A Problem With The Jacket Thermistor
Possible electrical open or short. These errors will
result if the temperature probe response is not within
the expected range. Probe substitution can be useful
in determining the cause of the problem (probe or
electronics). The valid working range of the probe
resistance is 1000 to 5000 ohms.
• Check connection to board
• Check quick disconnect between cables
• Replace probe
• Room temperature is below 10 °C (50 °F)
A/D Initialization Failed
Shortly after power is applied to the calorimeter
controller and the operating system has started, the
CPU attempts to read the unique IO board calibra-
tion information from the IO board. If the IO board is
not connected to the CPU, or the information on the
board is not valid, this error will be issued.
Bomb ID – Has Been Fired – Times Which Exceeds The Bomb
Service Interval
The calorimeter controller keeps track of how many
times the bomb has been fired. When this count ex-
ceeds a preset limit (usually 500) this message will be
issued each time the bomb is used for a test. Perform
bomb maintenance and reset the bomb fire count on
the Calibration Data and Control page for the appro-
priate bomb number.
You Have Exceeded The Run Data File Limit (1000 Files)
The memory set aside for test runs has been filled.
Use the memory management techniques to clear
out non-current tests. See page 31.
Bomb EE Standard Deviation Warning
The relative standard deviation for the calibration
runs in memory for the indicated bomb exceeds the
preset limit.
Sample Weight Warning
The entered sample mass exceeds the value entered
via the [Sample Weight Warning Above] key on the
Data Entry Controls page. This warning threshold is
normally 2 grams.
