GENERAL INFORMATION
1-1 INTRODUCTION
The informationcontained in thisoperations
manual isfor the installation, operation,
remote programming and optionand acces-
sory information for
the Lake Shore
Cryotronics, Inc.
Model 805 Temperature
Controller.
A separate Technical Service
Guide isavailablefor this instrument which
containsperformance and calibration
procedures, schematics, component layouts
and a replaceable parts list.
This section contains general informationfor
the Lake ShoreCryotronics, Inc.
805
Temperature Controller. Includedisan
instrumentdescription, specifications,
instrument identification, optionand
accessory information.
1.2 DESCRIPTION
The 805 Temperature Controller isa
microprocessor based instrument which
providestrueanalogcontrol.
It accepts
inputs from
up totwo sensors and displays
the temperature with up to4 digitsof
resolution
in K, °C or °F. It displays
voltage for diodes to 1
millivolt, andohms
for resistors to four places.
The dual sensor
input allowstheuserto
monitor temperature at more thanone point.
Sensor select pushbuttons on the front panel
enable the user todisplay either input at
will. The system control sensor isselected
via a rear-panel toggle switchwith the
choice indicatedon the front panel. This
choice isindependent of display status.
The Model 805 isdirect reading
in tempera-
ture when usedwith the Lake Shore DT-470
Series Temperature Sensors.
All DT-470
Sensors follow the same temperature
response curve. Four bands of tracking
accuracyare offeredsothat sensor selection
may be made with both technical and
economical considerationsfor any given
application. Low temperature (2to
100K)
accuracies range from 0.25K for band 11 to
1K for band 13. For more demanding
requirements, DT-470 Sensors can be indivi-
dually calibratedtoaccuracies of better
than
50 millikelvindepending on tempera-
ture range.
Diode sensor voltages aredigitizedwith a
resolutionof
100 microvolts out of 3 volts
full scale. For the display, temperature is
rounded to
0.1 kelvinabove 100 kelvin, and
to
0.01 kelvin below 100 kelvin.
For greater precision individual sensor
calibrations can be accommodated through
the 8001 Precision CalibrationOptionwhich
programs the instrument with a particular
response curve. The algorithmwithinthe
instrument interpolates between data points
toan interpolationaccuracy which exceeds
0.01K over the entire temperature range of
the PrecisionOption. The analog-to-digital
converter isaccurate toplus or minus the
least significantbit,which forthe470
series sensor results
in an uncertaintyof
1mK below 28K and45mK above 40K with a
transitional regionbetween the two
temperatures. Therefore, at temperatures
below 28K, the overall system accuracy, the
sum
of the instrument accuracy (11mK) and
that of the calibration itself (Lake
Shore
calibrationsare typically better than 20mK
withinthis region) is±0.03K. Above 28K,
system
accuracy gradually moderatesto a
typicalvalue of ±75mK above 40K. Seethe
Lake Shore Cryotronics, Inc. Low
Tempera-
tureCalibration Service brochure for
additionaldiscussion of calibrationaccuracy.
The 805 displayuses digital filteringwhich
averages up toten temperature readings.
This reading mode eliminates noisewithin
the cryogenic system analogous toaveraging
with a digital voltmeter. This algorithm
can be deselected (bypassed) by switch 2
of
the SENSOR ID dipswitch on the back
panel for a given
input if theuser prefers
not toaverage readings. Ablinking
decimal point at the upper leftof the
1-1

display indicates that averaging ison.
The Model805 can also be used with the
optional input conversion modules (-6) which
allow either input tobe converted tohandle
either the TG-120 series diodes
(orany
diode with a 0 to6 volt output), or positive
temperature coefficient metallic resistors.,
i.e., platinum (-P2 or -P3) or rhodium-iron
(-R1) resistors. The DIN curve isstandard
within the instrument and iscalled
up
automatically unless a precisionoption is
present forthe platinum resistor. The
accuracy
of the reading isdictated by the
sensor and itsconformity
tothe DIN curve.
The tolerance on these devices isgiven on
the technical data sheet for the Lake Shore
PT-100 series sensors. Thecombined
accuracy of the instrument and a calibrated
resistor with a precisionoption ison the
order of 40mK overthe useful range ofthe
sensor (above40K for the platinum). Note
that a precisionoption isrequired for a
rhodium-ironor a TG-120 toreadcorrectly
in temperature.
These
input conversionmodules are easily
installedby the user; thus, units can be
modified to satisfychanging requirements.
The ample memory space provided
in the805
allows several response curves to be stored
in one instrument. Depending on the
complexity of the curves, up totencanbe
programmed intothe unit. The
SENSOR ID
switches are used to select which particular
sensor response curve istobeusedwith
each
input. Thus, theuser isable tomake
sensor changes at
will even when different
response curves are required.
The data for calibratedsensors can be
stored within the instrumentby means of
the8001 PrecisionOption. Each curvecan
contain up to
99 sensor unit-temperature
data points. Withthe standardprecision
option format, which consists of 31data
pointsand a 20 character information line,
up totencurves can be stored
in the unit.
See Paragraphs3-6 through 3-10 for more
description.
A1though voltage (resistance)-temperature
data points arestoredas a table, interpola-
tionwithin the instrument results
in the
equivalent of a high order polynomial
calculation
in the converting ofthe input
voltage (or resistance) totemperature.
This isdone by means of a proprietary
algorithmdevelopedat Lake ShoreCryotro-
nics, Inc.
T he control temperature set - poi n t selection
ismade via thumbwheel switches on the
front panel oftheinstrument. The set-
point switches, which provide a continuous
indicationof the set-point value, enable the
user toquickly and easilydetermine
whether hissystem isatcontroltempera-
ture. The set-point isinthe same units as
is the Display sensor (kelvin, celsius,
fahrenheit, or volts [ohms]).
The control sectionof the805 provides
two-term temperature control. Proportional
(GAIN) and integral (RESET) are individual-
lytuned via front-panel potentiometers.
The gainmode isina nominal log per cent
with the reset being linear.
Analog heater output of
the 805 Tempera-
tureController isa maximum of
25 watts
when a 25 ohmheater isused. Adigital
meter on the front panel of the 805
continuously shows the heater power output
as a percentage of output range. Thus, the
user can conveniently monitor power applied
to hissystem. To accommodate systems
which require lower heater power, the
maximum heater output of the805 can be
attenuated intwo steps
of a decade each.
When greater power output isrequired,
an
optional 56 watt power output stage is
available (W60) which isdesigned
for a25
ohm load.
It isratedat a nominal 1.5
amperes and 45 volts.
An optional IEEE-488 (Model
8054) or RS-
232C (Model 8053) interface isavailable for
the 805. Either interfacecan beusedto
remotely control all front-panel functions.

Instrument specifications are listed inTable
1.2. These specifications are the perfor-
mance standards
or limits against which the
instrument is tested.
Option portsaredesigned intothe805 to
ease the additionof interfaces and outputs.
The Model 805 has two option portswhich
allow
up to two options to be used
simultaneously (see limitations below). The
options are easily installedby the user; thus,
units can be changed
or upgradedto satisfy changing require-
ments.
Only one computer interface can be
installed inthe805 due to space limitations
in the805 rear-panel. TheModel 8055
Analog Output option isavailable toprovide
