Hach ORBISPHERE 3100 Manuel D'utilisation Simplifié page 15

The numeric measurement value at the end of the curve is refreshed every 5 seconds. The curve is
refreshed every 5 seconds in sample mode. In continuous mode, the refreshment rate is the same as
that defined as the storage interval parameter.
The graphic timescale is displayed at the bottom of the screen. This value can be increased or
decreased (4 zoom levels) by pressing the up and down arrows on the keyboard. These values are
also dependant on the storage interval parameter; the greater the storage interval, the greater the
available timescale.
The measurement scale is calculated automatically with the maximum and minimum values
displayed at the top and bottom of the y axis respectively.
In sample mode, a square symbol is displayed to denote the end of the measurement . This is
displayed in green if the stop criteria are met, or red to denote an erroneous measurement.
The color of the curve has the following meaning:
• Grey (normal): The channel is out or the measurement is out of range
• Green (bold): The channel is being calibrated
• Grey (bold): The measurement has not started (sample mode only)
• Red (bold): An alarm has been activated
• Blue (bold): Normal measurement
5.6 Measurement configuration list
From the measurement screen, press the right arrow key until the list of measurement configurations
stored in the instrument is displayed.
Note: These configurations are defined by the user on the PC (see Create new measurement configuration table
on page 11) and imported into the instrument (see Transfer files to the instrument on page 11). Only the default
configuration (ID0) can be edited by the user from the instrument. To do this the user must be logged on at
supervisor level and the default parameters can then be edited from the Main Menu as described in Default
measurement configuration settings on page 19.
Press the up and down arrow keys to scroll through the list of measurement configurations. When the
required one is highlighted press the Enter key to select it. The selected configuration details will be
displayed on screen.
Press the Enter key again to select this configuration and return to the measurement screen, or
Cancel to reject it and return to the measurement configuration list screen.
5.7 Measurement alarms
If a problem occurs during measurement, the system will alternate every second between the
measurement screen and the error message screen.
The measurement value is displayed in red to indicate a measurement outside the pre-defined alarm
limits. The alarm low value on the right side of that screen is also displayed in red to indicate the
reason the measurement value is in error.
The error message screen gives the reason why the measurement is invalid.
Note: If the measured value goes back above this low value, the value is again displayed in blue and the error
message screen is no longer shown.
