Press System to access any of the following menu items.
The System menu will allow you to access the
setup options of the instrument including;
Date/Time, GLP, Language, Radix Point,
Logging, Sampling, Auto Shutoff, Backlight,
Sw (Software) Version, Serial #, and Unit ID.
Any item with [brackets] shows the current
setting inside the brackets. For instance, in the
example at the left, Radix Point is currently set
to [Decimal].
date/tIMe
Highlight Date/Time from the System menu. Press enter to select.
Date Format – Highlight and press enter to open a sub menu for selecting
the preferred date format: YY/MM/DD, MM/DD/YY, DD/MM/YY, or
YY/DD/MM.
Date – Highlight and press enter to use the numeric entry screen to set the
correct date.
Time Format – Highlight and press enter to open a submenu to select the
preferred time format from 12-hour or 24-hour.
Time – highlight and press enter to use the numeric entry screen to set the
correct time.
Glp
The GLP or ‘Good Laboratory Practice’ file saves detailed information
about calibrations. It also includes diagnostic information about the sensors.
Calibrations are logged into a file, the GLP, for later review as needed. A single
GLP file is utilized to store all calibration records and is capable of storing 500
records. Once the GLP file is full, the instrument will begin to overwrite the
oldest record with each new calibration record.
In order to keep all of your GLP records, periodically download
the GLP to Data Manager and export it to another program.
Otherwise, the instrument will overwrite the oldest record
once the memory is full. Also, since Data Manager saves
GLP files under the Unit ID, you must periodically export
and rename the GLP file on your PC or it will be overwritten
each time you upload the GLP file from the instrument.
Several calibration parameters are saved for each calibration including optional
ones that can be enabled by the user. Standard parameters include date/time
stamp, calibration method, and sensor information. Optional, user selectable
parameters include User ID, Probe ID, and User Fields 1 and 2.
In addition, there will be information specific to the Dissolved Oxygen or
Barometer calibration record. A Dissolved Oxygen calibration record will
contain the following calibration specific parameters:
DO
Sensor - Serial Number of the Sensor
Calibration Method - Zero, %, or mg/L
Cal Value
Sensor Value - Tangent of the angle between reference and signal LED, must be
within 0.2 of the default value in the sensor, typically between
-0.53 and -2.17
Salinity Mode - Always manual
Salinity Value - Value entered by the user
Barometer - Barometric Pressure during calibration
Temperature - Temperature during calibration
Calibrate Status - Calibrated
A Barometer calibration record will contain the following calibration specific
parameters:
Barometer
Barometer - Calibrate value in kPa
Calibrate Status - Calibrated
