Item Name Function
Block Temperature Temperature of the internal temperature block.
SETPOINT
Temperature
Target SETPOINT temperature. A set temperature value is referred to as
a “SETPOINT”. The Calibrator uses the SETPOINT value to know what
temperature to heat or cool to.
Reference
Temperature
[-P Only]
Shows the most recent reference measurement when a Reference PRT
probe is connected and set up. See “Reference PRT Connection
Preparation” on page 2-29.
UUT Output
[-P Only]
Shows the most recent UUT output measurement of a probe that is
connected and setup. The value shown depends on the output type
selected in the Input Setup Menu (see page 2-23).
Heating/Cooling
Status
Shows the mode the calibrator is in. The modes are: OFF, COOL, HEAT,
and CUTOUT. The bar under the mode corresponds to the percent
heating or cooling. The bar is blank at 0 % when HEATING or COOLING
is off or not necessary. The bar is completely dark at 100 % HEATING or
COOLING. CUTOUT is a feature that shuts off power to the heat source if
the well temperature exceeds the set limit value. CUTOUT shows when a
limit has been exceeded. For more information on CUTOUT, see “Cutout”
on page 2-13.
Stability Status
Indicator
Visually shows if the block temperature is stable and within the Stability
Limits.
When temperature of the internal temperature block is not within the
Stability Limits, the indicator shows a wavy line (
). When the
temperature is within the Stability Limits, the indicator shows as a flat line
(
---) which indicates that a measurement can be made. See “Stability
Limits” on page 2-12.
Note
To prevent inaccurate measurements, do not make
measurements until the Stability Indicator shows as a flat
line
(---).
