Manually changing tube calibration constants
If you discovered any errors in the values of the calibration constants
(see previous section), follow the directions in this section to manually
correct them using calibration information previously obtained for your
unit. If the calibration values are correct, instrument setup is complete.
NOTE This procedure for manually entering/changing calibration constants
bypasses the normal calibration procedure. To ensure the most accurate
viscosity readings, CANNON
® Instrument Company recommends that the
instrument be calibrated per the calibration procedure outlined in Chapter 3.
1. Log in as a Manager and click Configure from the VISCPRO ®
menu bar.
2. Select your instrument from the list of available instruments.
3. Select Calibration from the list of configuration options. The Cali-
bration window will appear (see next page).
The Calibration window provides controls for calibrating each bulb of
any viscometer associated with your instrument. You can click on the bulb
spin controls to display current constants and valid check standard
data available for calibration of each bulb.
Procedure
1. Make sure that the spin controls for Bulb are set to “ 1 ”:
This corresponds to the bottom bulb in the tube.
2. Check the values for the calibration constant(s) as they appear at the
bottom of the window:
