LIMITED WARRANTY STATEMENT
WARRANTY PERIOD: THREE (3) YEARS
1.Lake Shore warrants that products manufactured by Lake Shore (the
"Product") will be free from defects in materials and workmanship for
three years from the date of Purchaser's physical receipt of the Prod-
uct (the "Warranty Period"). If Lake Shore receives notice of any such
defects during the Warranty Period and the defective Product is
shipped freight prepaid back to Lake Shore, Lake Shore will, at its
option, either repair or replace the Product (if it is so defective) with-
out charge for parts, service labor or associated customary return
shipping cost to the Purchaser. Replacement for the Product may be
by either new or equivalent in performance to new. Replacement or
repaired parts, or a replaced Product, will be warranted for only the
unexpired portion of the original warranty or 90 days (whichever is
greater).
2.Lake Shore warrants the Product only if the Product has been sold
by an authorized Lake Shore employee, sales representative, dealer or
an authorized Lake Shore original equipment manufacturer (OEM).
3.The Product may contain remanufactured parts equivalent to new
in performance or may have been subject to incidental use when it is
originally sold to the Purchaser.
4.The Warranty Period begins on the date the Product ships from Lake
Shore’s plant.
5.This limited warranty does not apply to defects in the Product
resulting from (a) improper or inadequate installation (unless OT&V
services are performed by Lake Shore), maintenance, repair or calibra-
tion, (b) fuses, software, power surges, lightning and non-recharge-
able batteries, (c) software, interfacing, parts or other supplies not
furnished by Lake Shore, (d) unauthorized modification or misuse, (e)
operation outside of the published specifications, (f) improper site
preparation or site maintenance (g) natural disasters such as flood,
fire, wind, or earthquake, or (h) damage during shipment other than
original shipment to you if shipped through a Lake Shore carrier.
6.This limited warranty does not cover: (a) regularly scheduled or ordi-
nary and expected recalibrations of the Product; (b) accessories to the
Product (such as probe tips and cables, holders, wire, grease, varnish,
feedthroughs, etc.); (c) consumables used in conjunction with the
Product (such as probe tips and cables, probe holders, sample tails,
rods and holders, ceramic putty for mounting samples, Hall sample
cards, Hall sample enclosures, etc.); or, (d) non-Lake Shore branded
Products that are integrated with the Product.
7. To the extent allowed by applicable law, this limited warranty is the
only warranty applicable to the Product and replaces all other war-
ranties or conditions, express or implied, including, but not limited to,
the implied warranties or conditions of merchantability and fitness
for a particular purpose. Specifically, except as provided herein, Lake
Shore undertakes no responsibility that the products will be fit for any
particular purpose for which you may be buying the Products.
Any implied warranty is limited in duration to the warranty period. No
oral or written information, or advice given by the Company, its
Agents or Employees, shall create a warranty or in any way increase
the scope of this limited warranty. Some countries, states or provinces
do not allow limitations on an implied warranty, so the above limita-
tion or exclusion might not apply to you. This warranty gives you spe-
cific legal rights and you might also have other rights that vary from
country to country, state to state or province to province.
8.Further, with regard to the United Nations Convention for Interna-
tional Sale of Goods (CISC,) if CISG is found to apply in relation to this
agreement, which is specifically disclaimed by Lake Shore, then this
limited warranty excludes warranties that: (a) the Product is fit for the
purpose for which goods of the same description would ordinarily be
used, (b) the Product is fit for any particular purpose expressly or
impliedly made known to Lake Shore at the time of the conclusion of
the contract. (c) the Product is contained or packaged in a manner
usual for such goods or in a manner adequate to preserve and protect
such goods where it is shipped by someone other than a carrier hired
by Lake Shore.
9. Lake Shore disclaims any warranties of technological value or of
non-infringement with respect to the Product and Lake Shore shall
have no duty to defend, indemnify, or hold harmless you from and
against any or all damages or costs incurred by you arising from the
infringement of patents or trademarks or violation or copyrights by
the Product.
10.THIS WARRANTY IS NOT TRANSFERRABLE. This warranty is not
transferrable.
11.Except to the extent prohibited by applicable law, neither Lake
Shore nor any of its subsidiaries, affiliates or suppliers will be held lia-
ble for direct, special, incidental, consequential or other damages
(including lost profit, lost data, or downtime costs) arising out of the
use, inability to use or result of use of the product, whether based in
warranty, contract, tort or other legal theory, regardless whether or
not Lake Shore has been advised of the possibility of such damages.
Purchaser's use of the Product is entirely at Purchaser's risk. Some
countries, states and provinces do not allow the exclusion of liability
for incidental or consequential damages, so the above limitation may
not apply to you.
12.This limited warranty gives you specific legal rights, and you may
also have other rights that vary within or between jurisdictions where
the product is purchased and/or used. Some jurisdictions do not allow
limitation in certain warranties, and so the above limitations or exclu-
sions of some warranties stated above may not apply to you.
13.Except to the extent allowed by applicable law, the terms of this
limited warranty statement do not exclude, restrict or modify the
mandatory statutory rights applicable to the sale of the product
to you.

Electromagnetic Compatibility (EMC) for the Model 336 Temperature Controller
Electromagnetic Compatibility (EMC) of electronic equipment is a growing concern worldwide. Emissions of and
immunity to electromagnetic interference is now part of the design and manufacture of most electronics. To qualify
for the CE Mark, the Model 336 meets or exceeds the requirements of the European EMC Directive 89/336/EEC as a
CLASS A product. A Class A product is allowed to radiate more RF than a Class B product and must include the follow-
ing warning:
WARNING:This is a Class A product. In a domestic environment, this product may cause radio interference in which
case the user may be required to take adequate measures.
The instrument was tested under normal operating conditions with sensor and interface cables attached. If the
installation and operating instructions in the User's Manual are followed, there should be no degradation in EMC
performance.
This instrument is not intended for use in close proximity to RF Transmitters such as two-way radios and cell
phones. Exposure to RF interference greater than that found in a typical laboratory environment may disturb the
sensitive measurement circuitry of the instrument.
Pay special attention to instrument cabling. Improperly installed cabling may defeat even the best EMC protection.
For the best performance from any precision instrument, follow the grounding and shielding instructions in the
User's Manual. In addition, the installer of the Model 336 should consider the following:
DShield measurement and computer interface cables.
DLeave no unused or unterminated cables attached to the instrument.
DMake cable runs as short and direct as possible. Higher radiated emissions are possible with long cables.
DDo not tightly bundle cables that carry different types of signals.

The first of a new generation of innovative temperature measurement and control
solutions by Lake Shore, the Model 336 temperature controller comes standard
equipped with many advanced features promised to deliver the functionality and
reliable service you’ve come to expect from the world leader in cryogenic thermome-
try. The Model 336 is the only temperature controller available with four sensor
inputs, four control outputs, and 150 W of low noise heater power. Two independent
heater outputs providing 100 W and 50 W can be associated with any of the four sen-
sor inputs and programmed for closed loop temperature control in proportional-inte-
gral-derivative (PID) mode. The improved autotuning feature of the Model 336 can be
used to automatically collect PID parameters, so you spend less time tuning your con-
troller and more time conducting experiments.
The Model 336 supports the industry’s most advanced line of cryogenic temperature
sensors as manufactured by Lake Shore, including diodes, resistance temperature
detectors (RTDs) and thermocouples. The controller’s zone tuning feature allows you
to measure and control temperatures seamlessly from 300 mK to over 1,500 K by
automatically switching temperature sensor inputs when your temperature range
goes beyond the usable range of a given sensor. You’ll never again have to be con-
cerned with temperature sensor over or under errors and measurement continuity
issues. Alarms, relays, and ±10 V analog voltage outputs are available to help auto-
mate secondary control functions.

Model 336 Temperature Controller
Another innovative first from Lake Shore, the ability to custom label sensor inputs
eliminates the guesswork in remembering or determining the location to which a
sensor input is associated. As we strive to maintain increasingly demanding work-
loads, ease of use and the ability to stay connected from anywhere in the world are
critical attributes. With standard Ethernet, USB, and IEEE-488 interfaces and an intu-
itive menu structure and logic, the Model 336 was designed with efficiency, reliable
connectivity, and ease of use in mind. While you may need to leave your lab, Ethernet
ensures you’ll always be connected to your experiments. The new intuitive front
panel layout and keypad logic, bright graphic display, and LED indicators enhance the
user friendly front panel interface of the Model 336.
In many applications, the unparalleled feature set of the Model 336 allows you to
replace several instruments with one, saving time, money and valuable laboratory
space. Delivering more feedback, tighter control, and faster cycle times, the
Model 336 keeps up with increasingly complex temperature measurement and con-
trol applications. It is the ideal solution for general purpose to advanced laboratory
applications. Put the Model 336 temperature controller to use in your lab and let it
take control of your measurement environment.
1.1.1 Sensor Inputs The Model 336 offers 4 standard sensor inputs that are compatible with diode and
RTD temperature sensors. The field installable Model 3060 thermocouple input
option provides support for up to two thermocouple inputs by adding thermocouple
functionality to inputs C and D.
Sensor inputs feature a high-resolution 24-bit analog-to-digital converter; each
input has its own current source, providing fast settling times. All four sensor inputs
are optically isolated from other circuits to reduce noise and to provide repeatable
sensor measurements. Current reversal eliminates thermal electromotive force
(EMF) errors in resistance sensors. Nine excitation currents facilitate temperature
measurement and control down to 300 mK using appropriate negative temperature
coefficient (NTC) RTDs. Autorange mode automatically scales excitation current in
NTC RTDs to reduce self heating at low temperatures as sensor resistance changes by
many orders of magnitude. Temperatures down to 1.4 K can be measured and con-
trolled using silicon or GaAlAs diodes. Software selects the appropriate excitation cur-
rent and signal gain levels when the sensor type is entered via the instrument front
panel. The unique zone setting feature automatically switches sensor inputs,
enabling you to measure temperatures from 300 mK to over 1,500 K without inter-
rupting your experiment.
The Model 336 includes standard temperature sensor response curves for silicon
diodes, platinum RTDs, ruthenium oxide RTDs, and thermocouples. Non-volatile
memory can also store up to 39 200-point CalCurves for Lake Shore calibrated tem-
perature sensors or user curves. A built-in SoftCal™ algorithm can be used to gener-
ate curves for silicon diodes and platinum RTDs that can be stored as user curves.
Temperature sensor calibration data can be easily uploaded and manipulated using
the Lake Shore curve handler software.
1.1.2 Temperature
Control
Providing a total of 150 W of heater power, the Model 336 is the most powerful tem-
perature controller available. Delivering very clean heater power, it precisely controls
temperature throughout the full scale temperature range for excellent measurement
reliability, efficiency, and throughput. Two independent PID control outputs supply-
ing 100 W and 50 W of heater power can be associated with any of the four standard
sensor inputs. Precise control output is calculated based on your temperature set-
point and feedback from the control sensor. Wide tuning parameters accommodate
most cryogenic cooling systems and many high-temperature ovens commonly used
in laboratories. PID values can be manually set for fine control, or the improved

1 . 1 . 3 I n t e r f a c e 3
|www.lakeshore.com
autotuning feature can automate the tuning process. Autotune collects PID parame-
ters and provides information to help build zone tables. The setpoint ramp feature
provides smooth, continuous setpoint changes and predictable setpoint approaches
without the worry of overshoot or excessive settling times. When combined with the
zone setting feature, which enables automatic switching of sensor inputs and scales
current excitation through 10 different preloaded temperature zones, the Model 336
provides continuous measurement and control from 300 mK to 1505 K.
Control outputs 1 and 2 are variable DC current sources referenced to chassis ground.
Output 1 can provide 100 W of continuous power to a 25 ) load or 50 W to a 50 )or
25 )load. Output 2 provides 50 W to 25 )or 50 )heater loads. Outputs 3 and 4 are
variable DC voltage source outputs providing two ±10 V analog outputs. When not in
use to extend the temperature controller heater power, these outputs can function as
manually controlled voltage sources.
Temperature limit settings for inputs are provided as a safeguard against system
damage. Each input is assigned a temperature limit, and if any input exceeds that
limit, all control channels are automatically disabled.
1.1.3 Interface The Model 336 is standard equipped with Ethernet, universal serial bus (USB) and
parallel (IEEE-488) interfaces. In addition to gathering data, nearly every function of
the instrument can be controlled through a computer interface. You can download
the Lake Shore curve handler software to your computer to easily enter and manipu-
late sensor calibration curves for storage in the instrument’s non-volatile memory.
Ethernet provides the ability to access and monitor instrument activities via the
internet from anywhere in the world. The USB interface emulates an RS-232 serial
port at a fixed 57,600 baud rate, but with the physical plug-ins of a USB. It also allows
you to download firmware upgrades, ensuring the most current firmware version is
loaded into your instrument without having to physically change anything.
Each sensor input has a high and low alarm that offer latching and non-latching oper-
ation. The 2 relays can be used in conjunction with the alarms to alert you of a fault
condition and perform simple on/off control. Relays can be assigned to any alarm or
operated manually.
The ±10 V analog voltage outputs on outputs 3 and 4 can be configured to send a volt-
age proportional to temperature to a strip chart recorder or data acquisition system.
You may select the scale and data sent to the output, including temperature or
sensor units.

1.1.4 Configurable
Display
The Model 336 offers a bright, graphic liquid crystal display with an LED backlight
that simultaneously displays up to 8 readings. You can show all 4 loops, or if you need
to monitor 1 input, you can display just that one in greater detail. Or you can custom
configure each display location to suit your experiment. Data from any input can be
assigned to any of the locations, and your choice of temperature or sensor units can
be displayed. For added convenience, you can also custom label each sensor input,
eliminating the guesswork in remembering or determining the location to which a
sensor input is associated.
1.1.5 Three Option
Cards
Field installable input option cards can expand your sensor selection to include sili-
con diodes (like DT-670), capacitance sensors or thermocouples. Once installed, the
option input can be selected and named from the front panel like any other input
type. These option cards further expand the application versatility of the Model 336
temperature controller by allowing specialized sensors to be switched in and out to
achieve specific measurement objectives.
For example, addition of the thermocouple input option enables continuous mea-
surement to 1000 K and above. Alternatively, the capacitance sensor option card
enables a magnetics-impervious capacitance temperature sensor to be temporarily
switched in for elimination of magneto-resistive effects while taking low tempera-
ture sample measurements under high or changing fields. The 4-channel scanner
option card enables use of additional sensors for supplemental monitoring.
1.2 Sensor
Selection
Silicon diodes are the best choice for general cryogenic use from 1.4 K to above room
temperature. Diodes are economical to use because they follow a standard curve and
are interchangeable in many applications. They are not suitable for use in ionizing
radiation or magnetic fields.
Cernox™ thin-film RTDs offer high sensitivity and low magnetic field-induced errors
over the 0.3 K to 420 K temperature range. Cernox sensors require calibration.
Platinum RTDs offer high uniform sensitivity from 30 K to over 800 K. With excellent
reproducibility, they are useful as thermometry standards. They follow a standard
curveabove 70 K and are interchangeable in many applications.
