Temperature Controller:
The Eurotherm temperature controller shows the current temperature,
pressure, and setpoints. The temperature shown is the reading from either
the bath or slurry thermocouple, depending on the “Control Temp” value set in
“Testing Options”. See page 36 for more information.

Potentiometer Indicator:
The Potentiometer Indicator shows the DC voltage coming from the
potentiometer. This voltage is directly related to the consistency of the test
slurry (in Bc). The potentiometer has a range of 0 to 15 volts.
Status Indicator:
The lights on the Status Indicator correspond to the consistency of the
sample. The threshold values can be set in either the onboard controls or
in the software. There are three setpoints, specied in Bearden units of
consistency (Bc).
- Max Bc for Green Light: When the consistency is below this value, the
green light will be on.
- Max Bc for Green and Yellow: When the consistency is below this
value, the green and yellow lights will both be on.
- Max Bc for Red Light: When the consistency is below this value, the
yellow light only will be on. When the consistency is above this value,
the red light will be on and the test will stop.
Refer to page 38 for instructions on setting these values.
The Status Indicator also indicates an alarm condition. If an alarm is
triggered, all three lights on the status indicator will blink until the alarm is
acknowledged.
