ERROR MESSAGES
Detected errors and/or cautions can be displayed by the analyzer. From the main menu select [Err]. If
there are no error or caution messages, [NONE] will be displayed, otherwise scroll through the error list
using the Up and Down arrow keys. Errors and cautions cannot be removed from this list directly; each
error or caution will be removed automatically when appropriate, eg. errors associated with improper
calibration will be cleared after a
successful calibration.
Error messages are numbered. Errors 1
through 5 are identified as [En.e] where
n is the input number and e is the error
number. Messages 6 through 9 are less
serious and are identified as cautions
instead, eg. [CAn.e].
Off-scale errors for chlorine are not
numbered and are identified as [+Err]
and [-Err], depending on whether the
input is at the top or the bottom of the
scale. The off-scale error is displayed
instead of the sample reading and does
not show up in the error menu with the numbered error messages, if any.
Error message indicators can be annoying when one has already been made aware of them. A method
has been provided to turn off the error LED and the fault alarm for a particular error message. Refer to
Acknowledging an Error Message below for the exact procedure.
The error LED will remain on as long as there is an unacknowledged error or caution message or as long
as any input is off-scale. Each source of error must be removed or acknowledged before the error LED
will go off.
Acknowledging an Error Message
Select [Err] from the main menu. Use the Up or Down arrow key until the error message to be
acknowledged is displayed.
Errors are displayed with either a positive (+) sign or a negative sign (-) in front. The + sign is used to
indicate an active or unacknowledged error, the - sign indicates an inactive or acknowledged error.
Acknowledging the error will change the sign from + to -.
Press ENTER to go into edit mode. The + or - sign will be flashing. Use the Up or Down arrow key to
change the sign, then press ENTER again.
An acknowledged error message is cleared for one occurrence of the error only. If the error reappears,
the sign changes from - to + and the error message must be acknowledged again.
