Electrical Safety
lBefore using this equipment, make sure it is properly grounded. 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). If safety procedures are not followed, SEVERE INJURY OR DEATH may occur.
lDo not remove the panels from the equipment without proper safety measures to avoid internal
main power supply voltage hazard.
WARNING:
Follow these precautions to avoid electric shock or personal injury:
This equipment uses protective earth circuit to ensure that the conductive parts do not store electric
charges or conduct electricity if insulation fails
lBefore connecting the equipment to the electricity supply, understand the parts of the calibrator with
the help of operating manual.
lUse power cables only with appropriate voltage and power rating, and that are approved for usage in
your country.
lReplace the main power cable if the insulation is damaged, or if the insulation shows signs of wear and
tear.
lDO NOT put the product at the location where access to the main power is blocked.
lDO NOT use an extension cord or adapter plug.
lDO NOT use the product if it operates incorrectly.
lMake sure the power cord does not touch the hot parts of the product.

Health and Safety Instructions
WARNING: BURN HAZARD - DO NOT touch the well access surface of the unit at high temperature
To avoid possible health and safety concerns, follow these guidelines.
lWear appropriate protective clothing before using the equipment.
lOperators of this equipment should be adequately trained in the handling of hot and cold items and
liquids.
lDo not use the apparatus for jobs other than those for which it was designed, that is, the calibration of
thermometers.
lDo not handle the apparatus when it is hot (or cold), without wearing the appropriate protective
clothing and having the necessary training.
lDo not drill, modify or otherwise change the shape of the apparatus.
lDo not use the apparatus outside its recommended temperature range.
lAfter use, do not return the apparatus to its carrying case until the unit has cooled down.
lThere are no user serviceable parts inside. When required, contact Tempsens agent for repair.
lEnsure all materials, especially flammable materials are kept away from the hot parts of the apparatus,
to prevent fire risk.
lDo not use the product around explosive gas, vapor, or in damp or wet environments.
lMake sure that the space around the product meets minimum space requirements.
lDO NOT turn off the unit at temperatures higher than 350°C. This could create a hazardous situation.
Select a set-point less than 100°C and allow the unit to cool before turning it off.
lThe top sheet metal of the furnace may exhibit extreme temperatures for areas close to the well
access.
lMaterials used in this furnace may be irritating to skin, eyes, and respiratory tract. Consult the material
manufacturer's Material Safety Data Sheet (MSDS) to learn about those materials before using.

Cautions and Preventions
To avoid possible damage to the instrument, follow these guidelines:
lBefore working inside the equipment, turn the power off and disconnect the power cord.
lDO NOT turn the unit upside down with the inserts in place; the inserts will fall out of the unit.
lUse of this instrument at HIGH TEMPERATURES for extended periods of time requires caution.
lCompletely unattended high temperature operation is not recommended for safety reasons.
lDO NOT plug the unit into 230 V if the heater switches and fuse holder reads 115 V. This action will
cause the fuses to blow and may damage the instrument.
lComponents and heater lifetime can be shortened by continuous high temperature operation.
lDO NOT use fluids to clean out the well.
lNever introduce foreign material into the probe hole of the insert. Fluids and other materials can leak
into the calibrator causing damage.
lDO NOT drop or force the probe stems into the well. This type of action can cause a shock to the sensor
and affect the calibration.

Introduction
The CALsys 1700 used as calibrator for thermocouple calibration and it can be also used as a pyrometer
calibration with ceramic cavity.
The 'CALsys 1700' has been designed to provide stable and accurate temperature to enable professionals to
calibrate Temperature Sensing Devices (Thermocouple & pyrometer) by comparison method up to a
temperature range of 1700°C. The 'CALsys 1700L' model has been designed to be rugged and easily
maintained. This model provides an isothermal enclosure (Ceramic block) in which the thermocouple can
be calibrated against the temperature of the calibrator.
The 'CALsys 1700BB' model has been designed in single part. This model provides an isothermal enclosure
in which the Non-contact pyrometers can be checked against the temperature of the black body. For
traceable calibration a master pyrometer should be used. The units' features emissivity of 0.99, thus
offering the closest approximation of a target surface that is a perfect emitter of infrared energy.
1.1 About CALsys 1700
Back View Front View

Page | 10
CALsys 1700' is a transportable unit designed for use on any reasonable flat surface. The target is a ridged
Ceramic Tube Cavity which is painted by a high emissive paint .The target is heated by MoSi heaters which
2
allow the source to heat up to 1700°C in about 3Hrs and hold it stable at temperature within ±2.0°C. The
heater block house consists of a heater and the controller sensor. This sensor is used by the temperature
controller to sense the block temperature. To maintain a required temperature the controller varies the
power to the heaters via a power control device.
1.2 Basic Working Model of CALsys 1700
Before using the equipment, read the safety guidelines and operating procedures of the calibrator as
described in the of this user manual.
Important:

1. Connect the 'CALsys 1700BB' to a suitable power supply & set the controller to the required
Temperature.
2. After stabilization of the furnace, aim the reference standard thermometer to the center of cavity and
take the readings.
3. Repeat step 2 with the thermometer which is under calibration.
4. Find out the error by comparison method.
5. Always use a reference IR thermometer for comparison calibration method for 1700BB.
6. Check the D: S Ratio of the Pyrometer, it must be >10:1.
7. For CALsys 1700L place the ceramic insert in the calibrator.
8. Place the sensors for calibration and master sensor into a suitable insert hole.
4.3 Operating Instruction
4.2 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 furnace heater on or off to raise or lower the temperature. The
displayed temperature will gradually change until it reaches the set-point temperature. The furnace may
require time to reach the set-point depending on the span. An another 5 to 10 minutes is required to
stabilize the furnace with ± 1.5 Deg C of the set-point.
Important:
lAll other controller parameters are company set and locked. It is recommended not to change them.
lWhen the source is operated at any temperature above ambient, the front face and plate become hot.
lAlways put the fan in “ON” Condition and do not switch the “Mains” off Directly, First set the controller
to 0°C and then wait until the unit is not cooled below 350°C.
