To adjust the vacuum/pressure settings for the miniPV Series, click
Service from the VISCPRO menu options and select the desired instru-
ment group and instrument. Then click Adjust Vacuum/Pressure to
open the Adjust Vacuum/Pressure window.
Select the desired adjustment (vacuum or pressure) and then follow the
screen prompts to complete the adjustment procedure, using the appropri-
ate controls on the instrument wing panel. The prompts will display
recommended vacuum/pressure settings and will also indicate how
adjustments may be made to alter the settings.
To calibrate for temperature, see Chapter 3 for details. Temperature
calibration requires a reference thermometer with an accuracy meeting
the precision specification of ASTM D445.
To zero temperature offsets, click the Service/Clear Temperature
Offsets menu option for the desired instrument. The Zero Temperature
Offsets window will open. Click the check box to select each desired
action. Then click OK to clear the selected settings.
If the Clear Current Offset option is checked, VISCPRO will clear the
calibration point for the current bath temperature.
