1.1 Introduction
Fluke’s Hart Metrology Wells (9170, 9171, 9172, and 9173) are designed to be stable
heat sources that can be used in a laboratory or eld environment. With a calibrated
display and an optional built-in reference thermometer input (designated with “-R”),
Metrology Wells may also be used as a reference standard.
Metrology Wells feature interchangeable probe sleeves that t various sized diameter
probes.
The Metrology Wells’ controller uses a PRT sensor and thermoelectric modules or
heaters to achieve stable, uniform temperatures throughout the block.
The LCD display continuously shows many useful operating parameters including the
block temperature, block stability, heating and cooling status, and current set-point.
The temperature may be easily set with the control buttons to any desired temperature
within the calibrator’s specied range.
Metrology Wells are designed for laboratory performance that can be used anywhere.
With proper use, the instrument will provide continued accurate calibration of temper-
ature sensors and devices. Before use, the user should be familiar with the warnings,
cautions, and operating procedures of the calibrator as described in the Getting Started
Guide.

3
Before You Start
Safety Information
or has been in a wet environment, take necessary measures to remove moisture prior
to applying power such as storage in a low humidity temperature chamber operating at
50°C for 4 hours or more.
DO NOT use this instrument for any application other than calibration work. The
instrument was designed for temperature calibration. Any other use of the instrument
may cause unknown hazards to the user.
Completely unattended operation is not recommended.
DO NOT place the instrument under a cabinet or other structure. Overhead clearance
is required. Always leave enough clearance to allow for safe and easy insertion and
removal of probes.
Use of this instrument at HIGH TEMPERATURES for extended periods of time
requires caution.
Completely unattended high temperature operation is not recommended due to safety
hazards that can arise.
If the instrument is used in a manner not in accordance with the equipment design, the
operation of the Metrology Well may be impaired or safety hazards may arise.
This instrument is intended for indoor use only.
BURN HAZARD
Each Metrology Well is equipped with a Block Temperature Indicator (front panel
LED HOT indicator – U.S. Patent 7,561,058) even when the instrument is unplugged.
When the indicator is ashing, the instrument is not powered and the temperature of
the block is above 50°C. When the indicator is illuminated, always on, the instrument
is powered and the block temperature is above 50°C.
DO NOT turn the instrument upside down with the inserts in place; the inserts will
fall out.
DO NOT operate instrument in any orientation other than vertical (block opening face
up). Risk of re or burn hazard may result due to excessive heat build up.
DO NOT operate on a ammable surface or near ammable materials.
DO NOT touch the well access surface of the instrument.
The block vent may be very hot due to the fan blowing across the heater block of the
Metrology Well.
The calibration well temperature of the Metrology Well is the same as the actual dis-
play temperature, for example, if the instrument is set to 700°C and the display reads
700°C, the well is at 700°C.
The air over the well can reach temperatures greater that 200°C for high temperature
(400°C and higher) Metrology Wells.
Probes and inserts may be hot and should only be inserted and removed from the
instrument when the instrument is operating at temperatures below 50°C.

DO NOT turn off the instrument at temperatures higher than 100°C. This could create
a hazardous situation. Select a set-point less than 100°C and allow the instrument to
cool before turning it off.
The high temperatures present in Metrology Wells designed for operation at 300°C
and higher may result in res and severe burns if safety precautions are not observed.
ELECTRICAL HAZARD
These guidelines must be followed to ensure that the safety mechanisms in this instru-
ment will operate properly. This instrument must be plugged into a 115 VAC (230
VAC optional), AC only electric outlet. The power cord of the instrument is equipped
with a three-pronged grounding plug for your protection against electrical shock haz-
ards. It must be plugged directly into a properly grounded three-prong receptacle. The
receptacle must be installed in accordance with local codes and ordinances. Consult a
qualied electrician. DO NOT use an extension cord or adapter plug.
If supplied with user accessible fuses, always replace the fuse with one of the same
rating, voltage, and type.
Always replace the power cord with an approved cord of the correct rating and type.
HIGH VOLTAGE is used in the operation of this equipment. SEVERE INJURY or
DEATH may result if personnel fail to observe safety precautions. Before working
inside the equipment, turn power off and disconnect power cord.
1.3.2 Cautions
To avoid possible damage to the instrument, follow these guidelines:
To properly calibrate the Metrology Well, the “Fan Limit” must be set to “Auto.”
DO NOT leave the sleeve(s) in the instrument for prolonged periods. Due to the high
operating temperatures of the instrument, the sleeves should be removed after each use
and buffed with a Scotch-Brite® pad or emery cloth (see the Maintenance section of
the Users Guide).
Always operate this instrument at room temperature between 5°C and 50°C (41°F
and 122°F). Allow sufcient air circulation by leaving at least 6 inches (15 cm) of
clearance around the instrument. Overhead clearance is required. DO NOT place the
instrument under any structure.
DO NOT interchange inserts between Metrology Well models. The inserts provided
with the instrument as well as any additional inserts ordered are model specic.
Component lifetime can be shortened by continuous high temperature operation.
DO NOT apply any type of voltage to the switch terminals. Applying a voltage to the
terminals may cause damage to the controller.
DO NOT use uids to clean out the well. Fluids could leak into electronics and dam-
age the instrument.
DO NOT introduce any foreign material into the probe hole of the insert. Fluids, etc.
can leak into the instrument causing damage.

Before You Start
CE Comments
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 slam the probe sheath or sleeves into the well. This type of action can cause
a shock to the sensor and affect the calibration.
The instrument and any thermometer probes used with it are sensitive instruments that
can be easily damaged. Always handle these devices with care. DO NOT allow them
to be dropped, struck, stressed, or overheated.
DO NOT operate this instrument in an excessively wet, oily, dusty, or dirty environ-
ment. Always keep the well and inserts clean and clear of foreign material.
The Metrology Well is a precision instrument. Although it has been designed for opti-
mum durability and trouble free operation, it must be handled with care. Always carry
the instrument in an upright position to prevent the probe sleeves from dropping out.
The convenient handle allows for hand carrying the instrument.
If a mains supply power uctuation occurs, immediately turn off the instrument.
Power bumps from brown-outs could damage the instrument. Wait until the power has
stabilized before re-energizing the instrument.
The probe and the block may expand at different rates. Allow for probe expansion
inside the well as the block heats. Otherwise, the probe may become stuck in the well.
Most probes have handle temperature limits. Be sure the air temperature above the
Metrology Well does not exceed the probe handle’s temperature limit. If the probe
handle limits are exceeded, the probe may be permanently damaged.
