1.0 Use of products The following products are covered by this operating manual: TBT-T100IN TBT-T100IN US TBT-T100IN AUS The products listed above are general purpose immersion thermostats (T100IN) combined with a custom stainless steel tank (TBT) designed for tuberculosis testing for indoor laboratory use by a professional user. 2.0 How to use this operating manual This operating manual will allow you to unpack, set-up and operate the T100IN immersion thermostat correctly and safely.
3.0 Safety information 3.1 Safety compliance Grant immersion thermostats meet the requirements of international safety standard IEC 61010: Safety requirements for electrical equipment for measurement, control, and laboratory use. They also comply with the equivalent national standards including: EN 61010-2-010 UL 61010A-2-010 CAN/CSA-C22.2 NO. 61010-2-010-04. 3.
4.0 Operating instructions 4.1 Unpacking instructions Standard equipment includes: Immersion thermostat (T100IN) Tank (TBT) and bridge plate (TB-BTSIN) Tray Quilt Blanket Mains cord with plug (T100IN US has a fixed mains cord) Operating manual Remove packing materials carefully and retain them for future shipment or storage of the equipment. 4.2 Fitting controller to the tank 1. Fit the T100IN through the hole in the bridge plate and align using the locating threads.
4.4 Recommended liquids The following table lists the recommended liquids for different temperature ranges. Always ensure the liquid used is safe and suitable for your working temperature. If using non-recommended heat transfer liquids, it is the responsibility of the user to conduct an assessment to ensure the intended fluid is compatible with the T100IN and vessel.
5.0 Operating procedures 5.1 Operation 5.1.1 Constant level device A constant level device is fitted to the TBT tank to maintain the required liquid level. To use the constant level device, connect the inlet pipe (black) to the water supply and the outlet pipe (white) to a drain. The position of the top of the white/clear tube determines the water level. After filling the bath, adjust the water flow rate to the minimum which maintains a constant water level.
5.2 Using the T100IN 5.2.1 Product description Heater on light Alarm light Display Function button Select button Control dial Float switch 5.2.
5.2.3 Setting the control temperature The temperature of the bath liquid can be set using the S button. 1. Whilst the display is showing the bath temperature, press the S button. This will cause the display to flash indicating that it can be set. 2. Use the main dial to set the desired temperature. If no key is pressed for 10 seconds then the display will revert back to showing the bath temperature and the set temperature will remain at its original value. 3.
5.2.6 Completing a calibration The T100IN allows a two point calibration to be completed. The calibration menu can be accessed by simultaneously pressing the F and S buttons for about 5 seconds. The calibration temperatures are constrained by the temperature limits of the liquid type setting. Calibration should be carried out using a traceable reference thermometer with an accuracy of at least 0.1°C. This thermometer should be held securely in the centre of the bath or vessel.
5.2.7 Restoring factory calibration settings The restore factory calibration allows the unit settings to be reset if there is a problem during calibration or you wish to cancel any of the calibration settings. 1. Press the F and S buttons simultaneously for approximately 5 seconds until “LCAL” is shown. 2. Rotate the dial until the display shows “rST” and press the S button to select. 3. Press the S button four times (the display will show “Con.3”, “Con.2”, Con.

Water normally contains calcium or magnesium ions. De-ionised water has most ions removed as indicated by its conductivity level; the purer the water the lower the conductivity. It is important to use only de-ionised water from an ion exchange system with replaceable cartridges. Do not use de-ionised water generated from an ionexchange system that incorporates a salt back-flush system to regenerate the ionexchange resin as this can leave sodium ions that are very corrosive to stainless steel. 7.

11.0 Troubleshooting Symptom Possible cause Action required Display shows “Cut” Over-temperature cut-out has operated The heating element has exceeded 110°C. Allow the unit to cool and reset the over-temperature cut-out by switching the unit off and on again. If unit still shows a “Cut” alarm then the unit has an internal fault and must be repaired before it is used again.
Display shows “Open” Faulty temperature probe Have a competent person check the probe for an open circuit fault or contact Grant. Display shows “Shrt” Faulty temperature probe Have a competent person check the probe for a short circuit fault or contact Grant. Unit showing erratic temperatures Calibration values not Restore the factory calibration settings (see section set correctly 5.2.7) then re-calibrate if required (see section 5.2.6).
