2 Introduction
The Hart Scientific 9150 thermocouple furnace can be used for calibrating ther
mocouple 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
•
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 devices 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

4 Safety Guidelines
Operate the instrument in room temperatures between 5-50°C (41-122°F).
•
Allow sufficient air circulation by leaving at least 6 inches of space be
tween the instrument and nearby objects. Overhead clearance needs to al
low for safe and easy insertion and removal of probes for calibration.
The furnace is a precision instrument. Although it has been designed for
•
optimum durability and trouble free operation, it must be handled with
care. Always carry the unit in an upright position to prevent the probe
sleeves from dropping out. The convenient fold-up handle allows one
hand carrying. The instrument should not be operated in excessively wet,
oily, dusty, or dirty environments. It is important to keep the well of the
instrument clean and clear of any foreign matter. Do not operate near
flammable materials.
DO NOT use fluids to clean out the well.
•
The instrument can generate extreme temperatures. Precautions must be
•
taken to prevent personal injury or damage to objects. Probes may be extremely hot or cold when removed from the instrument. Cautiously handle
probes to prevent personal injury. Always use the special sleeve tongs that
are supplied with the calibrator to remove the sleeve. Carefully place
probes on a heat/cold resistant surface or rack until they are at room temperature. Never place any objects other than the special probe sleeves supplied with the calibrator into the well.
• Use only a grounded AC mains supply of the appropriate voltage to
power the instrument. Refer to Section 3.1, Specifications, for power details.
•
Before initial use, after transport, and anytime the furnace has not been
energized for more than 10 days, the instrument needs to be energized for
a “dry-out” period of 1-2 hours before it can be assumed to meet all of the
safety requirements of the IEC 1010-1.
•
The instrument is equipped with operator accessible fuses. If a fuse
blows, it may be due to a power surge or failure of a component. Replace
the fuse once. If the fuse blows a second time, it is likely caused by fail
ure of a component part. If this occurs, contact Hart Scientific Customer
Service. Always replace the fuse with one of the same rating, voltage, and
type. Never replace the fuse with one of a higher current rating.
•
If a mains supply power fluctuation occurs, immediately turn off the in
strument. Power bumps from brownouts and blackouts could damage the
instrument. Wait until the power has stabilized before re-energizing the
instrument.
•
Air circulated through the unit keeps the chassis cool. DO NOT SHUT
OFF THE FURNACE WHILE AT HIGH TEMPERATURES.

Place the calibrator on a flat surface with at least 6 inches of free space around
the instrument. Plug the power cord into a grounded mains outlet. Observe that
the nominal voltage corresponds to that indicated on the back of the calibrator.
Carefully insert the probe sleeve into the well. (DO NOT drop the sleeve in the
well.) Probe sleeve holes should be of the smallest diameter possible while still
allowing the probe to slide in and out easily. Sleeves with various hole sizes are
available from Hart Scientific. The well must be clear of any foreign objects,
dirt and grit before the sleeve is inserted. The sleeve is inserted with the two
small tong holes positioned upward.
Turn on the power to the calibrator by toggling the switch on the power entry
module. The fan should begin quietly blowing air through the instrument and
the controller display should illuminate after 3 seconds. After a brief self test
the controller should begin normal operation. If the unit fails to operate please
check the power connection.
