Cautions
Cautions
• To avoid possible damage to the instrument, follow t
guidelines.
• DO NOT plug the unit into 230 V if the heater switches and
fuse holder read 115 V. This action will cause the fuses to
blow and may damage the instrument.
• Components and heater lifetime can be shortened by
continuous high temperature operation.
• Most probes have handle temperature limits. Be sure that
the probe hand temperature limit is not exceeded in the air
above the unit.
• Allow for test probe expansion inside the well as the
furnace heats.
• DO NOT use fluids to clean out the well.

User's Guide
• Never introduce foreign material into the probe hole of the
insert. Fluids, etc. can leak into the calibrator causing
damage.
• DO NOT change the values of the calibration constants
from the factory set values. The correct setting of these
parameters is important to the safety and proper operation
of the calibrator.
• DO NOT drop or force the probe stems into the well. This
type of action can cause a shock to the sensor and affect
the calibration.
• DO use a ground fault interrupt device.

The Hart Scientific 9150 thermocouple furnace can be used for calibrating thermocouple and RTD temperature probes. Calibrations may be done over a range
of 150°C to 1200°C (302°F to 2192°F). Temperature display of the 9150 is 0.1
degrees below 1000°and 1 degrees above 1000°.
The furnace features:
• Rapid heating and cooling
• Interchangeable multiple hole probe sleeves
Chapter 2
Introduction
• Convenient handle
• RS-232 interface
Built in programmable features include:
• Temperature scan rate control
• Eight set-point memory
• Adjustable readout in °C or °F
The temperature is accurately controlled by Hart’s hybrid analog/digital controller. The controller uses a Type S thermocouple as a sensor and controls the
well temperature with a solid state relay (triac) driven heater. The furnace should
be calibrated yearly by trained personnel at Hart Scientific.
The LED front panel continuously shows the current well temperature. The
temperature may be easily set with the control buttons to any desired temperature within the specified range. The calibrator’s multiple fault protection de- vices
insure user and instrument safety and protection.
The 9150 calibrator furnace was designed for portability, low cost, and ease of
operation. Through proper use, the instrument will provide continued accurate
calibration of temperature sensors and devices. The user should be familiar with
the safety guidelines and operating procedures of the furnace as described in
this manual.
