4. Overview
4.1 Introduction:
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. For traceable calibration a master
calibration sensor should be placed into the metal block alongside the unit under calibration.
The method is widely accepted because the calibrator provides very stable temperature
nearing to its controlled point, the Master Thermocouple / RTD, which is calibrated by
independent Laboratory traceable to National standards, compares the sensor under
calibration.
The ‘CALsys’ models are part of wide range of portable calibrators designed and made by us.
Please contact us in case you required more information about our other products.
4.2 Outline Description:
‘The calibrator controller uses a precision R type thermocouple as a controlling sensor and
controls the well temperature with Kanthal spiral heater. To obtain and maintain a required
temperature the controller varies the power to the heater via solid-state relay. There is one
electricity driven fan which is situated under the heating chamber for cooling the heater. The
CALsys 1200 dry block calibrator was designed for portability, moderate cost and ease of
operation. With proper use the instrument should provide continued accurate calibration of
temperature sensors and devices. The user should be familiar with the safety guidelines and
operating procedures of the calibrator as described in the User’s Manual.
5. Operating Instruction
(1) PID Controller
(2) ON/OFF switch of heater
(3) Power cable
(4) RS-232 output
5.1 Power
Place the calibrator on a flat surface with at least 6 inches of free space around the instrument.
Overhead clearance is required. Do not place under a cabinet or structure. Insert equilizing block
into the well with help of tong, after inserting remove the tong from equalizing block. Plug the
power cord into mains outlet of the proper voltage, frequency Typically this will be (230 VAC ±10,
50/60 Hz). Turn the “Mains” (Heater) switch located on front panel. The controller dispaly should
illuminate after 3-4 sec . After a brief self test the controller should begin normal operation. If the
unit fails to operate please check the power connection.
5.2 Setting the Temperature
Press “UP” or “DOWN” buttons to change the change the temperature set-point value. When the
set-point temperature is changed the controller will switch the CALsys 1200 ON or OFF to raise or
lower the temperature. The displayed temperature will gradually change until it reaches the setpoint
temperature. The temperature bath requires 15 to 20 minutes to reach the set-point depending on
the span. Another 10 to 15 minutes is required to stabilize the temperature bath within ± 0.5ºC of
the set-point.
5.3 Operating Instruction:-
1. Insert the inconel block into well of furnace.
2. Connect the ‘CALsys 1200’ to a suitable power supply & Switch ON the Dry bath source and set
the desire temperature value in PID by using UP & Down key.
3. Insert the reference (Master) temperature sensor and UUC (Unit under calibration) into the
thermowell (inconel block).
4. PV (Present value) display in controller will gradually rise until it reaches the set point
temperature. The controller takes some times to reach the set-point depending on the span.
Furnace is stable when PV is equal to SV (Set Value).
5. Master sensor take some times to reach the setpoint temperature and stable at temperature
near about controller set temperature.
6. When temperature of the master and UUC (Unit under calibration) are stable record the
readings of master sensor.
7. Compare the UUC reading with the master’s reading & find out the error by comparison method.
8. Reset the controller and / or repeat the calibration for another calibration point or for another
sensor.
9. When the calibration is complete, reset the controller to 0°C & wait until the unit has cooled to
below 100°C, before moving the ‘CALsys 1200 to new location the ‘CALsys 1200’ must be cooled
below 100°C before it can be put back into its carrying case.
6. Operation of Controller

6.1 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.
6.2 Altering the Set point
To change the set point of the controller use the UP and DOWN keys to raise and lower the set
point to the required value. The lower display changes to indicate the new set point.
6.3 Monitoring the Controller Status
A row indicate the controllers status as follows
OP1 Heat Output
OP2 Cool Output
REM This beacon indicates activity on the PC interface
ALM this indicates when PV (Present value) is more than 1200°C.
6.4 Units
Momentary pressing of the Scroll key will show the controller units °C or °F by using SCROLL
key & UP & DOWN key unit can be change.
IMPORTANT NOTICE
The controller's function settings are preset and will not require adjustment. Use
only up & down key.
7. Maintenance & Trouble shooting
7.1 Maintenance
The calibration instrument has been designed with the utmost care. Ease of operation and
simplicity of maintenance have been a central theme in the product development.
Therefore, with proper care the instrument should require very little maintenance. Avoid
operating the instrument in an oily, wet, dirty, or dusty environment.
If the outside of the instrument becomes soiled, it may be wiped clean with a damp cloth
and mild detergent. Do not use harsh chemicals on the surface which may damage the
paint.
Avoid knocking or dropping the calibrator.
If the mains supply cord becomes damaged, replace it with a cord with the appropriate
gauge wire for the current of the instrument.
Depending on the environment in which it is used, periodic cleaning is recommended.
Cleaning may be accomplished by the use of a small dry paint brush.
7.2 Trouble shooting
1. Unit fails to operate
Check fuse if it is tripped switch is ON. If not power ON of calsys 1200 bath consult us.
2. Unit unstable
Controller parameter has been interfered, consult us.
3. If the temperature of the calibrator is not rising
(a) The heating element may be open.
(b) The thermocouple may be open.
(c) The SSR may be damaged.
(d) The controller may not be giving output
(e) The ambient temperature inside the chamber is raised and safety controller switched
OFF the power
