Thermo Electron Corporation V-2 Orion Star Series Meter
ISE
ISE Calibration Standard Concentration Range:
This selects the stability
criteria to be used in the ISE calibration. For most calibrations the HIGH setting is
the best option. But to maximize the accuracy of low concentration measurements
using low concentration calibration standards the LOW setting can improve
performance by giving the sensor longer to stabilize in the calibration standard.
ISE Auto-Blank Correction: This meter uses Thermo’s patented Auto-Blank
algorithm to compensate for sensor non-linearities in low-level measurements.
But since these require the solution of a set of non-linear equations that can only
be calculated numerically, the user cannot analytically verify the calibration. In
applications were that is a requirement the user can choose the turn the Auto-blank
correction OFF.
How to Change the ISE Setup Options
To access the ISE Setup Menu:
• From the Measurement Screen press the SETUP key.
a. If methods have been turned on then the Method selection screen will
appear when setup is pressed. Press the UP & DOWN arrows to select the
Method to be used or edited. Press the SETUP or RIGHT arrow key to edit
the selected method.
b. If a password has been setup, then the password entry screen will appear
and a password will need to be entered to enter setup and edit the method.
Press the UP & DOWN arrow keys to change the value of the flashing digit.
Press the DECIMAL/DIGIT key to change the digit to be scrolled. Press the
RIGHT Arrow key to move to enter setup. Press the MEASURE key to exit to
measurement mode.
• Press the UP & DOWN arrow to scroll through the Setup Menu until ISE is
displayed on the Top line.
• Press the RIGHT ARROW key to select the pH setup option line (Middle Line).
Press the MEASURE key to return to measurement mode.
