Error messages
Error messages are listed in alphabetical order, followed by a brief
description of the error condition, followed by what action the user can
take to correct the error (if possible).
A/D TIMEOUT
Return for service if error persists.
BAD BATTERY
Low battery voltage. Affects the clock and calendar. Replace the lithium
battery inside the instrument. See pg. 58.
BAD FLD CAL
Bad field calibration checksum. All field calibration values are erased.
Repeat field calibration if needed.
BAD SRVC CAL
Bad service calibration checksum. Usually requires service or repair to
correct. Until then defaults to last factory calibration.
CHKSUM ERROR
Bad program checksum. Usually requires service or repair to correct.
CONFIG ERR
Power down to clear error. Return for service if error persists.
ERASE ERROR
Internal memory error. Usually requires service or repair to correct.
NO CAL
Bad factory calibration checksum. This information is stored in the
microprocessor’s EEPROM and has been partially erased. Pressing the
“ALARM” button will clear the error message and allow the unit to func-
tion
without calibration: The unit will not meet published accuracy, but it
will operate.
OPEN
The channel is detecting a missing or open (defective) probe.
OVER
The channel is detecting a temperature that is above the maximum for
the selected thermocouple type.
SETUP ERROR
MENU setup items are invalid. Factory defaults are used. Repeat MENU
setup if needed.
UNDER
The channel is detecting a temperature that is below the minimum for the
selected thermocouple type.
VERIFY ERROR
Internal memory error. Usually requires service or repair to correct.
