Page 4: 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 5: 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 6: Do's And Don'ts
‘DO’S AND DON’TS’ DO ensure that after use the equipment is returned to ambient temperature and allowed to reach with 10°C of this temperature before transporting the equipment or returning to its carrying case. 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. -

Page 9: 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 10: Introduction
INTRODUCTION The Fast-Cal units allow flexibility for the calibration of temperature sensors. COMPARISON CALIBRATION By definition, one compares industrial thermometers to a calibrated standard. There are 3 methods commonly used. Basic Using the controller as the “calibrated standard” this method means that the complete bath is calibrated by comparing the controller reading to a calibrated standard placed in the bath. -
Page 11: Mode Of Operation
MODE OF OPERATION FAST-CAL HTM 2010 The metal block function of the Fast-Cal HTM 2010 is well suited for fast, convenient, mess free calibration of temperature sensors. The thermometers under test are placed into suitable holes in the block. For the S models a calibrated reference probe should be placed into the block and the actual temperature can be read from the temperature indicator. -
Page 12: The Reference Thermometer
The Industrial Thermometer is placed in the calibration volume 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 12 of 29... -

Page 15: Operating The Fast-Cal
OPERATING THE FAST-CAL 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 16: Instrument Address
Instrument Address The controller has a configurable "address" which is used for PC communications. Each instrument has an address; this allows several instruments to be connected in parallel on the same communications bus. The default value is 1. This address would only need to be changed if more than one Dry Block is connected to the same PC port. -
Page 17: Enabling/Disabling Custom Calibration
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 18: 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 19: 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 25: Initial Testing
INITIAL TESTING This unit was fully tested before despatch to you but please check its operation as outlined below. After connecting the Fast-Cal to the electricity supply, the temperature controller display will show the temperature of the block and the last set-point value. The S controller and indicator both go through a self-test sequence first. The fan on the front panel should be heard running. -
