Page 4: Guarantee
INTERFERENCE WITH OR FAILURE TO PROPERLY MAINTAIN THIS INSTRUMENT MAY INVALIDATE THIS GUARANTEE RECOMMENDATION The life of your ISOTECH Instrument will be prolonged if regular maintenance and cleaning to remove general dust and debris is carried out. We recommend that this instrument to be re-calibrated annually. -
Page 5: Emc Information
The Blue conductor should be connected to Neutral and the Brown conductor to Live (Line). Warning: Internal mains voltage hazard. Do not remove the panels. There are no user serviceable parts inside. Contact your nearest Isotech agent for repair. Voltage transients on the supply must not exceed 2.5kV. -
Page 6: Health And Safety Instructions
If cased, do not return the apparatus to its carrying case until the unit has cooled. There are no user serviceable parts inside. Contact your nearest Isotech agent for repair. Ensure materials, especially flammable materials are kept away from hot parts of the apparatus, to prevent fire risk. -
Page 7: 'Do's And Don'ts
‘DO’S AND DON’TS’ DO NOT handle the accessories when they are very hot or very cold. DO NOT place hot or cold accessories back in the carrying case DO NOT use the pocket designed for the black body source sensor to measure the temperature of the insert or surface calibrator. -

Page 10: Unpacking And Initial Inspection
UNPACKING AND INITIAL INSPECTION Our Packing Department uses custom designed packaging to send out your unit, but as accidents can still happen in transit, you are advised, after unpacking the unit, to inspect it for any sign of shipping damage, and confirm that your delivery is in accordance with the packing note. -
Page 11: Introduction
INTRODUCTION The Medusa range of products allows unprecedented flexibility for the calibration of temperature sensors. The Medusa may be used with the following options: An ITS-90 Fixed Point Apparatus As a Metal Block Bath A Black Body Source A Surface Sensor Calibrator The Medusa is available in two variants. -
Page 12: Using External Standards
USING EXTERNAL STANDARDS Here a separate indicator and calibrated sensor are used to measure the inserts temperature. This can give the most accurate and reliable results, depending on the indicator. It means that the calibrator does not need calibrating only the indicator and its calibrated sensor need re-calibration, but this option is more bulky, expensive and less portable than 2). -
Page 13: Mode Of Operation
MODE OF OPERATION ITS-90 FIXED POINT CALIBRATION The ITS-90 fixed point function of the Medusa is well suited for fast, convenient, mess free calibration of thermometers to uncertainties as low at 0.001°C. The special cell is placed into the Medusa calibration well. The equipment incorporates a timer which can change temperatures to allow MELTING or FREEZING of a Cell. -
Page 14: Black Body Source
BLACK BODY SOURCE The black body function of the Medusa is well suited for fast, convenient, mess free calibration of infra-red temperature sensors. The Medusa black body target, see accessory page, is placed into the calibration well. The units under test should be aligned with the target. -

Page 16: Thermometric Fixed Points (A Tutorial Note)
THERMOMETRIC FIXED POINTS (a tutorial note) Temperature scales used in science and industry are defined by a series of "fixed points", which are realised by establishing thermal conditions under which pure materials exhibit equilibrium between two or three phases. A scale assigns numerical values to the temperatures at which these phase equilibria exist. -
Page 17: Hint On How To Measure The True Temperature Inside The Accessories Supplied With The Medusa Series
The Industrial thermometer is placed in the accessory or insert and is compared to the True Temperature as indicated by the reference thermometer. An insert will typically have a 1% immersion error.

Page 21: Operating The Medusa
OPERATING THE MEDUSA FRONT PANEL LAYOUT THE TEMPERATURE CONTROLLER The controller has a dual display, the upper display indicates the nominal block temperature, and the lower display indicates the desired temperature or setpoint. ALTERING THE SETPOINT To change the setpoint of the controller simply use the UP and DOWN keys to raise and lower the setpoint to the required value. -
Page 22: Instrument Address
When the SPrr is active the controller display will show "RUN", the lower setpoint display will now automatically update with the current value, known as the working setpoint. The setpoint can be seen by pressing either the UP and DOWN key. The Setpoint ramp rate operates when the bath is heating and cooling. -
Page 23: Enabling / Disabling Custom Calibration
User calibration can make a significant difference to the accuracy of the instrument, and this REM beacon provides a clear and continuous indication of the calibration status. Isotech will configure and set user calibration when the Dry Block is ordered with a temperature sensor. -
Page 24: Monitoring The Indicator Status
The indicator can be configured with up to five custom calibration points; the points contain "data pairs". First the temperature (point) and secondly the Error (offset) at this temperature point. Isotech Dry Block calibration certificates will show the values to suit a particular sensor. -
Page 25: Calibration Data Example
CALIBRATION DATA EXAMPLE A maximum of five points may be entered, shown as Pnt 1 to Pnt 5 for the temperature point and Ofs 1 to Ofs 5 for the offset values. The Pnt values must be entered in ascending order. Set a Pnt to a value lower than the previous point to disable it. -
Page 26: Connecting A Current Transmitter (Up To 20Ma)
CONNECTING A CURRENT TRANSMITTER (UP TO 20MA) The transmitter should be powered externally, a 2.49Ω current sense resistor is fitted internally and this allows the indicator to read mA. From the input type menu select “mV”. Access configuration level. SELECTING CONFIGURATION LEVEL Page 26 of 41 Medusa 510/511 Series Iss.11 –... -
Page 27: Testing Thermostats
Testing Thermostats The Site model can be used the Isotech Cal Notepad software for the testing of thermostats and other thermal switches with volt free contacts. Cal Notepad can capture the temperature at which a switch opens or closes. It can also perform a hysteresis test. -
Page 28: Operating The Medusa 511
OPERATING THE MEDUSA 511 The Medusa 511 is a 3 Zone Block Bath used to create an even temperature profile along the part of the block in which fixed point cells will sit. The main heater is used to set the required temperature the top and bottom heaters are used to compensate for the end effect heat losses. -

Page 33: Initial Testing
INITIAL TESTING This unit was fully tested before despatch to you but please check its operation as outlined below. After connecting the Medusa to the electricity supply, the temperature controller display will show the temperature of the block and the last set-point value. The controller and indicator both go through a self-test sequence first. Change the set-point to 100°C and observe that the block temperature rises and settles to this value. -
