Calibration Error
If this screen is displayed after calibration is complete, the internal
diagnostics have determined that the calibration fluid or the flow
through cuvette requires replacement. Check the calibration fluid and
cuvette and then recalibrate or restore the factory calibration. The
instrument cannot be used without performing one of these operations.
See Restoring Factory Settings section for more information.
To recalibrate, press the
MODE
key and start the calibration sequence
again.
Restore Factory Settings
If the instrument is unable to perform a calibration due to a low lamp
output, bad calibration standard or a dirty cuvette, the instrument will
display
CAL
and
Err
on the display. If the problem is determined to be
a poor calibration or low lamp, fix the problem and recalibrate. If the
problem cannot be determined, the instrument must be restored to the
factory calibration and configuration settings.
To restore factory settings:
1. Push and hold the
button.
2. Push and release the
button and then release the
button.
The instrument has now been restored to it’s original factory settings.
Instrument Configuration
(CONFIG Mode)
The instrument has the ability to be customized at any time during
operation.
CONFIG
Mode has been split into sub-menus to facilitate
instrument configuration. While in Configuration Mode, the instrument
has a time-out feature that automatically returns the system operation
to
AUTO
mode after a 15 minute period.
To enter
CONFIG
Mode:
1. Press the
MODE/EXIT
button until the arrow next to
CONFIG
is
illuminated.
2. Press the
button. You are now in
CONFIG
Mode.
3. To exit
CONFIG
Mode, press the
MODE/EXIT
button.
Selecting the Output (O/P)
The first configuration sub-menu is the O/P. The O/P options are:
•
4-20
for the 4-20 mA output
•
485
for the RS-485 and modbus
•
OFF
if no outputs are required
1. Using the
and
buttons, select the desired output.
2. Once the desired output has been selected, press the
button to
set it.
The next prompts will depend on the output selected. For RS-485 and
Modbus, certain combinations of settings are not allowed and some
menus will not appear based on previous selections.
Setting the 4-20 mA
If the 4-20 mA output was selected, you will be asked to set the 4mA
(
4MA
) and 20mA (
20MA
) %T or ABS limit levels.
1. Select the %T or ABS level you wish to assign to the
4MA
setting
using the
and
buttons. The factory setting is 90%T or 0 for
ABS.
2. Once the desired level has been selected, press the
button to set it.
The 4MA level cannot be set higher than the 20 MA level.
3. Select the %T or ABS level you wish to assign to the
20MA
setting
using the
and
buttons. The factory default setting is 100%T or
2 for ABS.
4. Once the desired level has been selected, press the
button to set it.
The 20MA level cannot be set lower than the 4MA level.
Setting the Error Level
In case of an error in the AccUView LED Ex, the 4-20 mA reading can
be used to indicate a problem by sending the output to either:
• 4.00 mA
• 2.00 mA
• 0 mA
• OFF - In the case of OFF, the 4-20mA is unaffected by any error
condition. OFF is the factory default setting.
1. Select the desired
ERLV
using the
and
buttons.
2. Once the desired level is selected, press the
button to set it.
Configuring the RS-485 Port
If the instrument is wired for this option and the I/O selection is
changed to
485
, prompts will appear for setting the baud rate and the
address.
Setting the Baud Rate
1. Select the desired baud rate (1200, 2400, 4800, 9600 or 19200) for
operation of the I/O using the
and
buttons. Factory setting is
19200 baud.
2. Once the desired baud rate is selected, press the
button to set it.
Restoring the factory settings allows the use of the AccUView
LED Ex with reduced accuracy. The original problem still
exists and must be determined and corrected before accurate
operation of the AccUView LED Ex will be resumed. The
AccUView LED Ex will always reset to %T and factory defaults
after restoring.
