1.1 Introduction
Beamex Metrology Temperature Blocks (MB140, MB155, MB425, and MB700) are
designed to be stable heat sources that can be used in a laboratory or eld environ-
ment. With a calibrated display and an optional built-in reference thermometer input
(designated with “-R”), Metrology Temperature Blocks may also be used as a refer-
ence standard.
Metrology Temperature Blocks feature interchangeable probe inserts that t various
sized diameter probes.
The Metrology Temperature Blocks’ 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 temperature block’s specied range.
Metrology Temperature Blocks are designed for laboratory performance that can
be used anywhere. With proper use, the instrument will provide continued accurate
calibration of temperature sensors and devices. Before use, the user should be familiar
with the warnings, cautions, and operating procedures of the block as described in the
users manuals.

3
Before You Start
Safety Information
the product is wet or has been in a wet environment, take necessary measures to re-
move 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 Temperature Block may be impaired or safety hazards may
arise.
This instrument is intended for indoor use only.
BURN HAZARD
Each Metrology Temperature Block is equipped with a Block Temperature Indica-
tor (front panel LED HOT indicator – Patent Pending) 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 block access surface of the instrument.
The block vent may be very hot due to the fan blowing across the heater block of the
Metrology Temperature Block.
The calibration block temperature of the Metrology Temperature Block is the same as
the actual display temperature, for example, if the instrument is set to 700°C and the
display reads 700°C, the block is at 700°C.
The air over the block can reach temperatures greater that 200°C for high temperature
(400°C and higher) Metrology Temperature Blocks.
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 Temperature Blocks designed for opera-
tion 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 230 VAC (115
VAC optional), AC only electric outlet. The power cord of the instrument is equipped
with a grounding plug for your protection against electrical shock hazards. It must be
plugged directly into a properly grounded 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 Temperature Block, the “Fan Limit” must be set
to “Auto.”
DO NOT leave the insert(s) in the instrument for prolonged periods. Due to the high
operating temperatures of the instrument, the inserts 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 15 cm (6 in) of clearance
around the instrument. Overhead clearance is required. DO NOT place the instrument
under any structure.
DO NOT interchange inserts between Metrology Temperature Block models. The in-
serts provided with the instrument as well as any additional inserts ordered are model
specic.

Before You Start
CE Comments
DO NOT introduce any foreign material into the probe hole of the insert. Fluids, etc.
can leak into the instrument 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 block.
DO NOT slam the probe sheath or inserts into the block. 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 block and inserts clean and clear of foreign material.
The Metrology Temperature Block is a precision instrument. Although it has been de-
signed for optimum durability and trouble free operation, it must be handled with care.
Always carry the instrument in an upright position to prevent the probe inserts 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 in-
side the block as the block heats. Otherwise, the probe may become stuck in the block.
Most probes have handle temperature limits. Be sure the air temperature above the
Metrology Temperature Block does not exceed the probe handle’s temperature limit. If
the probe handle limits are exceeded, the probe may be permanently damaged.

3.2 Setup
NOTE: The instrument will not heat, cool, or control until the “CONT
ENABLE” parameter is set to “On.” Refer to Set-Point Setup on page 16 to set
this parameter.
Place the block on a at surface with at least 15 cm of free space around the instru-
ment. Overhead clearance is required. DO NOT place under a cabinet or structure.
Plug the Metrology Temperature Block power cord into a mains outlet of the proper
voltage, frequency, and current capability (see Specications for power details). Ob-
serve that the nominal voltage corresponds to that indicated on the back of the block.
Carefully place the probe insert into the block. Probe inserts should be of the small-
est hole diameter possible still allowing the probe to slide in and out easily. Inserts
of various sizes are available from Beamex. The block must be clear of any foreign
objects, dirt and grit before the insert is installed. The insert is installed with the two
small tong holes positioned upward.
Turn on the power to the temperature block by toggling the switch on the power entry
module. After a brief self-test, the controller should begin normal operation. The main
screen will appear within 30 seconds. If the instrument fails to operate, please check
the power connection.
The display will show the block temperature, and wait for user input before heating or
cooling to current set-point.

3.4.1 Measure
Stability Limit
NOTE: Metrology Temperature Blocks should not be expected to operate better
than the stability limit specification set forth in the Specifications section of this
guide. Therefore, the minimum setting of the stability limit should not be less
than the stability specification set forth in the Specifications section.
The stability limit of the instrument is the parameter which allows the instrument to
notify the user when it has achieved the stability limit set in this parameter. There are
two notications: visual and audible. The visual notication is always active. When
the instrument is operating within the stability limit, the stability parameter on the
main screen will remain highlighted as long as the instrument is within the given
specication, otherwise the parameter will not be highlighted. The audible, if enabled,
alerts the user once per set-point when the instrument achieves the set stability limit.
Use the numeric keys to set the desired stability limit and press “ENTER” to accept
the new stability limit.
Example:
A specic calibration process requires the instrument be operating within ±0.1°C.
“0.1” would be entered into the stability limit parameter. When the instrument is
within ±0.1°C, “STAB: X.XXX°C” will be highlighted and the audible alarm (if
enabled) will notify the user that the instrument is operating within ±0.1°C. Use the
numeric keys to set the desired stability limit and press “ENTER” to accept the new
stability limit.

3.5 Setting the Temperature
The users guide explains in detail how to set the temperature set-point of the tempera-
ture block using the front panel keys. The procedure is summarized here.
3.5.1 Set-point Setup
1. From the main screen, press “ENTER” once to access the “SETUP SET
POINT” menu.
2. Press +/- to set a positive or negative temperature. If the “-” symbol is not
present, the temperature is assumed to be positive. Use the number keys to set
the desired temperature. Press “ENTER” to set the temperature and continue
setting up the set-point information. If the other information in the set-point
menu does not need to be edited at this point, press “EXIT” to return to the
main screen
NOTE: Each time the instrument is turned off and back on, the “CONT
ENABLE” parameter is set to “Off”.
3. The “CONT ENABLE” parameter enables or disables active heating or cooling
of the instrument. This parameter must be set to “On” for the instrument to heat
or cool. Using the right/left arrow keys, select “On” to allow the instrument to
heat or cool or select “Off” to disable heating and cooling.
4. The scan rate of the instrument can be set from 0.1 to 99°C/min, however
the actual scan rate is limited by the natural heating or cooling rate of the
instrument. Use the number keys to set the desired scan rate and press
“ENTER”.
When the set-point temperature is changed the controller will switch the thermoelec-
tric modules or heater on or off to raise or lower the temperature. The displayed block
temperature will gradually change until it reaches the set-point temperature. The block
may require 5 to 10 minutes to reach the set-point depending on the span. Another 5 to
10 minutes is required to stabilize with ±0.1°C of the set-point. Ultimate stability may
take 15 to 20 minutes more of stabilization time.
3.6 Reference Probe (-R models only)
The reference probe section of the user manual explains in detail how to set up the
reference probe of the temperature block using the front panel keys. The procedure is
summarized here.
