3.2 CALIBRATION PROCEDURES
WARNING: Calibration reagents may be hazardous to your health. Refer to Appendix A for
health and safety information.
A calibration cup is supplied with the Model 6000
UPG
. Because the calibration cup fits over the
outside of the sonde probe guard, it is not recommended or necessary to remove the probe guard to
calibrate the sensors. Follow the procedures below to calibrate the sensors. Temperature does not
require calibration and is, therefore, not included in the Calibrate menu. ORP calibration is
required only infrequently and is discussed in Section 4.2. For more detailed calibration
procedures, which can be used to enhance the accuracy of some measurements, see Section 4.2.
The following sequence is provided as an EXAMPLE of the process the user will utilize to
calibrate all sensors. Although conductivity was chosen for this general example, more detailed
instructions for the calibration of the conductivity sensor are found in the next section.
From the sonde Main menu select 2. Calibrate.
The Calibrate menu will be displayed.
Selection of any of the parameters from the Calibrate menu listing will require the user to input a
numerical value and then press Enter. For example, for calibration of the conductivity sensor, you
should select 1. Conductivity from the Calibrate menu and then 1. SpCond from the Cond
Calibration menu. The following display will be shown during the calibration sequence.
