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)

SEVERE INJURY OR DEATH may result if personnel

fail to observe safety precautions.

•

Do not remove the panels from the equipment without proper safety measures to avoid

internal main power supply voltage hazard.

To avoid possible electric shock or personal injury, follow these guidelines

This equipment uses protective earth circuit to ensure that the conductive parts do not store electric

charges or conduct electricity if insulation fails.

•

Before connecting the equipment to the electricity supply, understand the parts of the calibrator with

the help of operating manual.

•

Use power cables only with appropriate voltage and power rating, and that are approved for usage in

your country

•

Replace the main power cable if the insulation is damaged, or if the insulation shows signs of wear

and tear

•

DO NOT put the product at the location where access to the main power is blocked.

•

DO NOT use an extension cord or adapter plug.

•

DO NOT use the product if it operates incorrectly

•

Make sure the power cord does not touch the hot parts of the product

Preface

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

•

Wear appropriate protective clothing before using the equipment

•

Operators of this equipment should be adequately trained in the handling of hot and cold items and

liquids

•

Do not use the apparatus for jobs other than those for which it was designed, that is, the calibration

of thermometers

•

Do not handle the apparatus when it is hot (or cold), without wearing the appropriate protective

clothing and having the necessary training

•

Do not drill, modify or otherwise change the shape of the apparatus

•

Do not use the apparatus outside its recommended temperature range

•

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

•

Do not use the product around explosive gas, vapor, or in damp or wet environments

•

Make sure that the space around the product meets minimum space requirements

•

DO NOT turn off the unit at temperatures higher than 100°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

•

The top sheet metal of the furnace may exhibit extreme temperatures for areas close to the well

access

•

Materials 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

Dry Block Temperature Calibrator (CALsys 650)

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

•

Use of this instrument at HIGH TEMPERATURES for extended periods of time requires caution

•

Completely unattended high temperature operation is not recommended for safety reasons

•

DO 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.

•

Components and heater lifetime can be shortened by continuous high temperature operation.

•

DO NOT use fluids to clean out the well.

•

Never introduce foreign material into the probe hole of the insert

Fluids and other materials can leak

into the calibrator causing damage

•

DO 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

About CALsys 650

CALsys 650 has been designed to provide stable and accurate temperature to enable professionals to

calibrate temperature sensing devices by comparison method

It is 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

This method is widely accepted because the calibrator provides very stable

temperature nearing to its controlled point, that is, the Master Thermocouple/RTD

The controlled

point is calibrated by independent laboratory in compliance to the national standards, and compares

the sensor under calibration.

The CALsys models are part of wide range of portable calibrators designed and made by Tempsens.

Dry Block Temperature Calibrator (CALsys 650)

User’s Guide

Basic Working Model of CALsys 650

The purpose of the CALsys 650 is to provide an isothermal enclosure for calibration purpose

The

heater block contains a heater and a control sensor that are 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 which is situated

under the heating chamber for cooling the heater

The fan runs continuously.

The calibrator controller uses a precision N-type thermocouple as a controlling sensor and controls

the well temperature with MI 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

Important:

Before using the equipment, read the safety guidelines and operating procedures of the calibrator as

described in the Preface of this user manual.

The basic working model for CALsys 650 is as follows:
