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: Cautionary Note
CAUTIONARY NOTE ISOTECH PRODUCTS ARE INTENDED FOR USE BY TECHNICALLY TRAINED AND COMPETENT PERSONNEL FAMILIAR WITH GOOD MEASUREMENT PRACTICES. IT IS EXPECTED THAT PERSONNEL USING THIS EQUIPMENT WILL BE COMPETENT WITH THE MANAGEMENT OF APPARATUS WHICH MAY BE POWERED OR UNDER EXTREMES OF TEMPERATURE, AND ARE ABLE TO APPRECIATE THE HAZARDS WHICH MAY BE ASSOCIATED WITH, AND THE PRECAUTIONS TO BE TAKEN WITH, SUCH EQUIPMENT. -
Page 8: Unpacking And Initial Inspection
THE APPARATUS MUST BE CORRECTLY EARTHED (GROUNDED) The units on/off switch is located on the power inlet. Take care NOT to switch the unit off when it is hot - allow to cool first. Page 8 of 39 Oceanus-6 Series Model 580 Iss.08 – 04/15... -
Page 9: Oceanus-6 Model 580 'Do's And Don'ts
DO NOT try to straighten the working standard, it is deliberately bent so that it does not interfere with the sensors you are calibrating. Page 9 of 39 Oceanus-6 Series Model 580 Iss.08 – 04/15... -
Page 10: Introduction
This is a common method but is unsafe since the control sensor is inaccessible in the wrong place to give correct temperature of the insert For these reasons it fails to satisfy ISO9000 and gives large uncertainties. Page 10 of 39 Oceanus-6 Series Model 580 Iss.08 – 04/15... -
Page 11: Using The Indicator (Not Basic (B) Model)
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 above. It also meets ISO9000 requirements. Page 11 of 39 Oceanus-6 Series Model 580 Iss.08 – 04/15... -
Page 12: Mode Of Operation
The stirrer speed control is set ON and to the mid position. If necessary the speed to can be adjusted to give the optimum value for a particular application, this position should be found experimentally and then noted for future use. Page 12 of 39 Oceanus-6 Series Model 580 Iss.08 – 04/15... -
Page 13: Stirred Ice Bath
A calibrated probe (part number 935-14-84) is placed in the pocket of the surface sensor insert and connected to the temperature indicator. Surface sensors are placed on top of the insert and when stable compared to the calibrated probe. Page 13 of 39 Oceanus-6 Series Model 580 Iss.08 – 04/15... -

Page 15: Using Water & Gallium Fixed Point Cells
Set the Oceanus-6 to give a well temperature of approximately 32°C. Monitor the Cell until the Gallium starts to melt, at this stage the well temperature can be lowered to 30.5°C which will give a long melt plateau. Page 15 of 39 Oceanus-6 Series Model 580 Iss.08 – 04/15... -
Page 16: Slim Gallium Cell
The magnitude of these effects may be checked (i) by reducing the immersion depth and (ii) by making measurements at two currents through the thermometer. SLIM GALLIUM CELL Please see separate handbook for this cell. Page 16 of 39 Oceanus-6 Series Model 580 Iss.08 – 04/15... -
Page 17: Thermometric Fixed Points (A Tutorial Note)
Alternatively, once the melt has begun the water in the well can be replaced by warm water at say 40°C to initiate a melt round the re-entrant tube. See CCT96/8 for additional guidance. Page 17 of 39 Oceanus-6 Series Model 580 Iss.08 – 04/15... -
Page 18: Hint On How To Measure The True Temperature Inside The Accessories Supplied With The Oceanus-6 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. For more details see - Depths of Immersion. Tavener J. P. Volume 9.2. Isotech Journal of Thermometry pages 79-87. Page 18 of 39... -

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 21 of 39 Oceanus-6 Series Model 580 Iss.08 – 04/15... -
Page 22: Instrument Address
Check that any sensor placed into the Oceanus-6 is suitable for the temperature range. Sensors can be damaged if taken outside their normal operating limits. The desired sensor type is easily set, press the Scroll key until the upper display indicates, inPt Page 22 of 39 Oceanus-6 Series Model 580 Iss.08 – 04/15... -
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. -
