5.4.2 Initiating temperature calibration
•
Press blue key 2 to select temperature calibration.
•
Follow temperature calibration steps as shown on screen.
•
Press STOP to exit and return to previous menu.
Use an RTD calibrator (not provided) for calibrating temperature.
Temperature calibration is always performed in Celsius (°C).
5.4.3 Initiating sensor calibration
•
Press blue key 3 to begin sensor calibration (Figure 5-8).
•
Choose the appropriate standard for the spring (Table 5-2). The instrument
will prompt you to use the appropriate fluid.

When ready, press

to start (Figure 5-10).
The unit will step through different speeds and compile sensor
data. When this process finishes, the user will be prompted to
enter the viscosity (cP) of the fluid at the measured temperature.
The system uses this reference measurement (cP) to correlate
the table it has compiled, and then it calibrates the dial readings
to offset for nonlinearities in the measurement system.
