Preface Welcome to the Dry Block Temperature Calibrator (CALsys 1200) user guide. This guide provides detailed information about all the product options and features, and explains how to use the product and configure basic settings to suit your requirements. This user manual contains information about the product and its proper use and should be kept in a place where it will be easy to access.
Temperature Calibrator (CALsys 1200) User's Guide Electrical Safety WARNING: ·This equipment must be correctly grounded before use. Make sure the ground conductor wire (colored green/yellow) in the main power cable is connected to a protective earth/ground. If the equipment is not properly grounded, the high voltage may flow through the equipment body (chassis).
After use, do not return the apparatus to its carrying case until the unit has cooled down. There are no user serviceable parts inside. When required, contact Tempsens agent for repair. Ensure all materials, especially flammable materials are kept away from the hot parts of the apparatus, to prevent fire risk.
Temperature Calibrator (CALsys 1200) User's Guide Cautions and Preventions To avoid possible damage to the instrument, follow these guidelines: Before working inside the equipment, turn the power off and disconnect the power cord. DO NOT turn the unit upside down with the inserts in place; the inserts will fall out of the unit.
Introduction 1.1 About CALsys 1200 The 'CALsys 1200' has been designed to provide stable and accurate temperature to enable professionals to calibrate Temperature Sensing Devices by comparison method. The 'CALsys 1200' model has been designed to be rugged and easily maintained. This model provides an isothermal enclosure (Metal block) in which the thermocouple/RTD can be calibrated against the temperature of the calibrator.
1.2 Basic Working Model of CALsys 1200 The purpose of the CALsys 1200 is to provide an isothermal enclosure for calibration purpose. The heater blockhouses a heater and a control sensor used by the temperature controller to sense the block temperature.
Introduction 1.5 Technical Specification CALsys 1200 has the following technical specifications: PARAMETER SPECIFICATION Temperature Range 250 to 1200°C Accuracy ±2°C ± 0.1°C at 250°C Stability ± 0.2°C at 700°C ± 0.3°C at 1200°C ± 0.20°C at 250°C Radial Uniformity ± 0.30°C at 700°C ±...
Chapter 2 Setting up CALsys 1200 2.1 Installation Place the dry block calibrator on a flat surface with at least 10 inches of free space around the instrument. Overhead clearance is required. DO NOT Place this unit under a cabinet or structure. Plug the power cord into a grounded mains outlet located on the controlling unit rear panel.
CAlsys 1200 is packed in custom-designed packaging to send out your unit. Unpack the furnace carefully. Inspect the unit after unpacking for any signs of damage, and confirm that your delivery is in accordance with the packing note. If you find any damage to the unit or an item is missing, notify Tempsens immediately.
This unit is fully tested before dispatching. However, verify its operation as follows: 1. After connecting the CALsys 1200 to the electricity supply, the temperature controller display should show the temperature of the chamber, and the last set-point value. The fan on the bottom should be heard running.
Chapter 3 Operating CALsys 1200 3.1 Turning On the unit 1. Before plugging the unit to main power outlet, ensure that the voltage, frequency and current from the main power outlet are within the recommended rages (typically: 230 VAC±10, 50/60 Hz).
9. Reset the controller and/or repeat the calibration for another calibration point or for another sensor. 10.When the calibration is completed, reset the controller to 0°C. Before moving CALsys 1200 to new location the unit must be cooled to below 100°C.
Take the reading of sensors (master and test) at stable temperature with the help of digital multi- meter, or by using Tempsens' TEMPMET 08 or TEMPMET 09 for reading RTD or TC sensor. 3.4 Cooling Down the Source Before transporting the metal block, ensure that the temperature of bath has cooled sufficiently.
Chapter 4 Operating Unit Controller 4.1 Front Panel Layout The following image shows the front panel of CALsys 1200 Measured Temperature Required Temperature * PAGE SCROLL DOWN 4.2 The Temperature Controller The controller has a dual display, the upper display indicates the measured temperature, and the lower display indicates the desired temperature or set point.
Operating Unit Controller 4.4 Monitoring the Controller Status A row of beacons indicates the controllers status as follows: OP1: Heat Output Ÿ OP2: Cool Output (only for models which operate below 0°C) Ÿ REM: This beacon indicates activity on computer interface Ÿ...
Chapter 5 Digital Communication Digital Communication allows the controller to communicate with a PC or a networked computer system through USB protocol. USB is a standard communication protocol for linking computer and its peripheral devices to allow serial data exchange. USB communication is not available if Remote Set point is fitted. The cable screen should be grounded at one point only to prevent earth loops.
Chapter 6 Software Installation The provided Tempsens software offers possibilities to connect furnace temperature bath and change set point, maximum time span, view real time graph and evaluate measuring data. 6.1 Installation Install the calibration software using the installation guide file on PAN Drive. After installing the software, start the application.

Software Installation PVI Value displays the current present value of furnace temperature. The Scale Trend section enables you to configure Y-Axis Min (minimum value: 0), Y-Axis Max (maximum value: 1500), Maximum Time Span of data logging up to 120 minutes, and then click the Start Graph button.
Turn the electricity supply off before attempting any cleaning operation. The only moving part in this unit is fan, which is sealed for life. Depending on the environment in which CALsys 1200 is used, periodic cleaning is recommended. Cleaning may be accomplished by the use of a small dry paint brush. The instrument should be periodically checked to ensure it is in good order both mechanically and electrically.
8.1 CALsys 1200 unit does not turn on If the CALsys 1200 unit does not turn on or operate as usual, check if the fuse is broken, and replace the fuse if necessary. If the fuse breaks repeatedly, contact Tempsens for technical support.
