Operation
10.1 Example of Running a Thickening Time Test
The steps listed below are for experienced users who are familiar with
consistometer operation.
A light coating of grease on the threads is important to prevent
cement from filling the threads.
Do not pound the lid closed with a sledgehammer. It is
recommended that the lid be loosened a few degrees to allow
easy removal after a test is finished.
1.
Turn the instrument on. Depress the red LED POWER switch to the ON

Once CementLab has loaded press Test Setup and program a temperature
and pressure ramp as described in the Test Setup section.
4.
Mix the slurry and fill the slurry cup.
5.
Prior to placing the slurry cup and potentiometer mechanism (pot mech)
into the pressure vessel, place the pot mech onto the assembled slurry cup
and fit the drive disc and bar using the supplied hex key and drive bar set
screw.
6.
Place the slurry cup then the potentiometer mechanism (pot mech) into the
pressure vessel using the supplied slurry cup and potentiometer bails.
Engage the slurry cup to the cup table. The motor may be turned on now
using the motor button. Engage the pot mech onto the drive shaft bar
making sure the top pot mech bearing is aligned with the paddle shaft.
