Indicators
Most indicators turn on once, then off; only the confidence indicator persists, repeating every 90 seconds. If
all signal* settings are on, indicators will look and sound like this:

Failures and Errors
Some failures and errors are easily resolved by qualified personnel (see Table 6.3 below). For other errors
or failures, contact Industrial Scientific for assistance.
Table 6.3 Failures and errors
The sample display screen (left) indicates a sensor failure. The position of the “F” means it is the LEL
sensor that is in failure. As noted below, different abbreviations or symbols are used to indicate other
failures and errors.
Symbols
Cause
Recommended actions
F
only
The sensor is in a general
state of failure and is not
operational.
Power off the instrument, then power it back on.
If the failure persists, check the sensor for
proper installation.
ERR
The sensor is installed in the
wrong location.
Install the sensor in its correct location.
The sensor failed the zero
process.
Repeat the zero process.
BUMP
and
F
The sensor failed bump
testing.
Calibrate the instrument, then complete a bump
test.
CAL
and
F
The sensor failed calibration. Calibration results indicate the sensor’s span
reserve percentages. When that value is less
than 50%, the sensor will not pass calibration
and is due for replacement. If the span reserve
percentage indicates the sensor is greater than
