EEPROM CSUM FAULT A fault has been detected in the EEPROM.
ADCx FAULT
The analog / digital converter 1 or 2 has failed to initialize or failed
self-calibration.
LOW
Low Battery power detected and displayed before shut down.
LOW TEMP
Displays in step 1 of the sensor test screen, if the input temperature
is too low for the sensor to function. Oxygen sensors operate at
temperatures above 1100°F (600°C). This value is set in the Setup
menu / PROBE / MIN PROBE TEMP parameter. This value can be
modified or disabled if the temperature is not connected as an
input, assuming the sensor is operating above the minimum range.
CHANGE TO OUTPUT MODE This prompt displays temporarily when at sensor test is
attempted but the PROBE BUDDY is in the output mode. The
sensor test can only run when the PROBE BUDDY is connected to
a valid sensor mV signal.
The front panel display will show
LLLL
if the process value is below the display resolution or
signal range.
HHHH
will appear as the process value if signal is above the input range or
display resolution. It may be necessary to adjust the exponent and/or the decimal point
settings if these symbols occur.
