Calibration and Measurement
The Orion Dual Star meter can perform a one to six point pH calibration, a two to six point ISE
(concentration) calibration, a one point ORP calibration and a one point temperature calibration.
Step-by-step instructions and prompts are displayed on the meter to assist operators with the
calibration menus. A calibration graph, which includes the electrode slope between points and
the average slope, can be viewed in the calibration mode for pH and ISE (concentration)
calibrations. The meter can save up to 10 calibrations per channel in the log and calibration
data can be exported from the meter to a printer or computer.
pH Calibration and Measurement
pH Calibration Hints
•
The measurement mode (displayed to the right of the measurement value) determines the
type of calibration that the meter will perform. Set the measurement mode to pH for the
channel that will be calibrated. Refer to the
Setup Menu
section for instructions on setting
the measurement mode.
•
Prepare and condition the pH electrode per the instructions in the electrode user guide.
•
Make sure that the pH electrode, ATC probe and reference electrode (if applicable) are
connected to the meter inputs that correspond with the channel that will be calibrated.
•
Always use fresh pH buffers for calibration. Choose buffers that are 1 to 4 pH units apart.
•
The meter will automatically recognize the US buffer set (pH 1.68, 4.01, 7.00, 10.01 and
12.46 buffers) or the EURO buffer set (pH 1.68, 4.01, 6.86 and 9.18 buffers). The default
meter setting is the US buffer set.
