The 'CALsys 650' has been designed to provide stable
and accurate temperature to enable professionals to
calibrate Temperature Sensing Devices by comparison
method. The 'CALsys 650' 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.
1.1 Basic Working of CALsys 650
The purpose of the CALsys 650 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. 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 in the unit. It runs continuously and situated
under the heater chamber for cooling the heater, it runs
when PV exceeds the set value.
The calibrator controller uses a precision N type
thermocouple as a controlling sensor and controls the
well temperature with MI 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 650
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.

Operating Instruction
5.1 Power
Plug the calibrator power cord into mains outlet of the proper voltage, frequency and current capability. Typically this
will be (230 VAC±10, 50/60 Hz). Turn the controller using the “Mains”(user main power panel) and set the
temperature value in the controller. After this, ON the ON/OFF switch which is provided in back side of furnace.
5.2 Heating up the source
Press “UP” or “DOWN” key of controller to change the set-point value. When the set-point temperature is changed
the controller will switch the calibrator heater on or off to raise or lower the temperature. The displayed temperature
will gradually change until it reaches the set-point temperature. The Calibrator may require 15 to 20 minutes to reach
the set-point depending on the span. An another 5 to 10 minutes is required to stabilize the bath temperature within
± 0.1°C of the set-point.
Note
All other controller parameters are company set and locked. It is recommended not to change them.
When the source is operated at any temperature above ambient, the front face and plate become hot.
Always put the fan in “ON” Condition and do not switch the “Mains” off Directly, First set the controller to 0 Deg C and then
wait until the unit is not cooled below 100 Deg C.

5.3 Operating Instruction
1. Connect the 'CALsys 650' to a suitable power supply.
2. Place the metal insert in the bath.
3. Place the sensors for calibration & master sensor into a suitable insert hole.
4. Put insulation on top of the furnace so that it covers only metal insert (brass block) section. please note at
very high temperature we will recommended to use ceramic wool, it will improve stability time.
5. Set the controller to the required Temperature.
6. If test & master sensor is Thermocouple then always use compensating cable (for each type like J, K, T, E, N, R,
S, B) for interconnection between sensor and DMM.
7. Keep reference junction at 0 Deg C, if not possible then ADD mili volt (mV) of room (ambient) temperature
with sensors output mV to compensate the ambient temperature.
8. When temp of the controller are stable record the reading from DMM with at least 41/2 digit precision which
should be calibrated for the measuring range (mV & ohms measurements).
9. Find out the error by comparison method.
10. Reset the controller and / or repeat the calibration for another calibration point or for another sensor.

Note
1. Metal Insert should be of required hole size so that the hole size is suitable for sensor under calibration.
2. Always use a master sensor (master RTD/TC) for comparison calibration method.
3. Place the metal insert first then all sensors and then set controller at desired set point.
4. Check that all sensors (test & master) are immersed at same depth in insert (metal block).
5. If sensors are not immersed at same depth than there will be an error in temperature reading.
6. Always use a metal block calibrator. Metal block calibrator (insert) heat transfer characteristics should match those of the
normal measuring situations.
7. The temperature sensors should be long enough so that immersed a calibration bath, errors due to stem conduction can be
ignored.
8. Do not change the set value suddenly until the temperature reaches to existing set value.
Ex. : The set value is 100°C and when it reaches at 80°C now you set 150°C, this is improper method / incorrect method.
9. Plan the calibration point in increasing way then set the controller accordingly. This method will save the time.
10. Take the reading of sensors (master & test) at stable temperature with the help of Digital Multimeter or by using Tempsens
make TEMPMET 08 or TEMPMET 09 for reading RTD or TC sensor.
5.4 Cooling down the Source
Risk of Burns
1. Before transport the metal block, ensure that the temperature of bath has cooled sufficiently.
2. If the metal block can be brought quickly from higher temperature to lower temperature set the temperature
to the room temperature (ambient temperature).
3. Always cool the heated instrument to ambient temperature before disconnecting it from the mains,
switching it OFF / removing the temperature sensor / test item.
4. Always leave a heated instrument supervise / under observation.

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 of beacons indicate the controllers status as follows,
OP1 Heat Output
OP2 Cool Output (only for models which operate below 0°C)
REM This beacon indicates activity on the PC interface
6.4 Units
Momentary pressing of the Scroll key will show the controller units °C or °F.
IMPORTANT NOTICE
The controller's function settings are preset and will not require adjustment.

Digital Communications
RS-232 is a standard communication protocol for linking
computer and its peripheral devices to allow serial data
exchange. RS-232 communications uses the Modbus
protocol. Rs-232 communications is not available if
Remote Set point is fitted. Cable screen should be
grounded at one point only to prevent earth loops.
Digital Communications (or 'comms' for short) allows
the controller to communicate with a PC or a networked
computer system.
7.1 Digital Communications Wiring
To use EIA232 the PC will be equipped with an EIA232
port, usually referred to as COM 1. To construct a cable
for EIA232 operation use a three core screened cable.
The terminals used for EIA232 digital communications
are listed in the table below. Some PC's use a 25 way
connector although the 9 way is more common.
* These are the functions normally assigned to socket pins.
Please check your PC manual to confirm.
