Introduction
1 Before You Start
1.1 Introduction
Field Temperature Blocks (FB150, FB350, and FB660) are designed to be reliable,
stable heat sources that can be used in the eld or laboratory. They offer accuracy,
portability, and speed for nearly every eld calibration application. The instruments
have been designed with the eld user in mind and are easy to use while maintaining
stability, uniformity, and accuracy comparable to some laboratory instruments.
Special built-in features make Field Temperature Blocks extremely adaptable. The
exclusive Voltage Compensation allows the technician to plug into mains power with
voltage from 90 V ac to 250 V ac without degradation to the instrument. The Ambient
Temperature Compensation provides the largest operating range in the industry (0°C
to 50°C) with the largest guaranteed temperature range (13°C to 33°C). The Gradient Temperature Compensation keeps the axial gradient within specication over the
entire temperature range of the instrument and over the specied guaranteed operating temperature range. These combined features along with the rugged design, light
weight, and small size make this line of instruments ideal for eld applications.
Unique Patent Pending safety features make these the safest eld heat sources available. The unique Air Flow Design keeps the probe handle cool protecting delicate
instruments and the user. The Block Temperature Indicator shows the user when the
well temperature is above 50°C letting the user know when it is safe to remove the
insert or move the instrument. The indicator light illuminates when the instrument is
energized and the well is above 50°C. If the instrument is removed from mains power,
the indicator light ashes until the well has cooled to less than 50°C.
The optional “-R” version (“FBXXX-R”) combines the heat source with a built-in
reference.
The Field 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, the current set-point, block stability, and heating and cooling status.
For the -R version, the reference temperature readings are displayed. The display can
be set to show the information in one of eight different languages; English, Japanese,
Chinese, German, Spanish, French, Russian, and Italian.
The instrument’s rugged design and special features make them ideal for the eld or
the laboratory. With proper use, the instrument provides 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 User’s
Guide.

CE Comments
around the instrument. Overhead clearance of 1 meter (3 ft) is required. DO NOT
place instrument under any structure.
Component lifetime can be shortened by continuous high temperature operation.
DO NOT use uids to clean out the well. Fluids could leak into electronics and damage the instrument.
Never introduce any foreign material into the probe hole of the insert. Fluids, etc. can
leak into the instrument causing damage.
Unless recalibrating the instrument 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 allow the probe sheath or inserts to drop 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 environment. Always keep the well and inserts clean and clear of foreign material.
The Field Temperature Block is a precision instrument. Although it has been designed
for optimum durability and trouble free operation, it must be handled with care. Al-
ways carry the instrument in an upright position to prevent the 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
inside the well as the block heats. Otherwise, the probe may become stuck in the well.
Most probes have handle temperature limits. If the probe handle limits are exceeded,
the probe may be permanently damaged. Due to a unique Air Flow Design, Field Tem-
perature Blocks protect the probe handle temperature and provide a safer temperature
handle for the user.
1.5 CE Comments

FBXXX Field Temperature Blocks
CE Comments
8
The instrument was designed specically as a test and measuring device. Compliance
to the EMC directive is through IEC 61326-1 Electrical equipment for measurement,
control and laboratory use.
As noted in the IEC 61326-1, the instrument can have varying congurations. The
instrument was tested in a typical conguration with shielded RS-232 cables.
1.5.2 Immunity Testing
Using Clamp-On Ferrites
For the –R model only, clamp-on ferrites are provided for use in improving its electromagnetic (EM) immunity in environments of excessive EM interference. During EMC
testing we found that ferrites clamped around probe cables for the Reference PRT input reduced the risk the EM interference affects measurements. Therefore, we recommend that the clamp-on ferrites provided be used on the cables of probes attached to
the readout, especially if the product is used near sources of EM interference such as
heavy industrial equipment.
To attach a ferrite to a probe cable, make a loop in the cable near the connector and
clamp the ferrite around half of the loop as shown in the diagram. The ferrite can be
easily snapped open and moved to a new probe when needed.
