1.1 Introduction

Beamex Metrology Temperature Blocks (MB140, MB155, MB425, and MB700) are

designed to be stable heat sources that can be used in a laboratory or eld environ-

ment. With a calibrated display and an optional built-in reference thermometer input

(designated with “-R”), Metrology Temperature Blocks may also be used as a refer-

ence standard.

Metrology Temperature Blocks feature interchangeable probe inserts that t various

sized diameter probes.

The Metrology Temperature Blocks’ controller uses a PRT sensor and thermoelectric

modules or heaters to achieve stable, uniform temperatures throughout the block.

The LCD display continuously shows many useful operating parameters including the

block temperature, block stability, heating and cooling status, and current set-point.

The temperature may be easily set with the control buttons to any desired temperature

within the temperature block’s specied range.

Metrology Temperature Blocks are designed for laboratory performance that can

be used anywhere. With proper use, the instrument will provide continued accurate

calibration of temperature sensors and devices. Before use, the user should be familiar

with the warnings, cautions, and operating procedures of the block as described in the

users manuals.

Examples include household, office,

and laboratory appliances.

1.3 Safety Information

Use this instrument only as specied in this guide. Otherwise, the protection provided

by the instrument may be impaired. Refer to the safety information in the Warnings

and Cautions sections below.

The following denitions apply to the terms “Warning” and “Caution”.

 “Warning” identies conditions and actions that may pose hazards to the user.

 “Caution” identies conditions and actions that may damage the instrument

being used.

1.3.1 Warnings

To avoid personal injury, follow these guidelines.

GENERAL

DO NOT use this instrument in environments other than those listed in the User’s

Guide.

Inspect the instrument for damage before each use. DO NOT use the instrument if it

appears damaged or operates abnormally.

Follow all safety guidelines listed in this guide.

Calibration equipment should only be used by trained personnel.

If this equipment is used in a manner not specied by the manufacturer, the protection

provided by the equipment may be impaired.

Before initial use, or after transport, or after storage in humid or semi-humid environ-

ments, or anytime the Metrology Temperature Block has not been energized for more

than 10 days, the instrument needs to be energized for a “dry-out” period of 2 hours

before it can be assumed to meet all of the safety requirements of the IEC 1010-1. If

Before You Start

Safety Information

the product is wet or has been in a wet environment, take necessary measures to re-

move moisture prior to applying power such as storage in a low humidity temperature

chamber operating at 50°C for 4 hours or more.

DO NOT use this instrument for any application other than calibration work. The

instrument was designed for temperature calibration. Any other use of the instrument

may cause unknown hazards to the user.

Completely unattended operation is not recommended.

DO NOT place the instrument under a cabinet or other structure. Overhead clearance

is required. Always leave enough clearance to allow for safe and easy insertion and

removal of probes.

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

requires caution.

Completely unattended high temperature operation is not recommended due to safety

hazards that can arise.

If the instrument is used in a manner not in accordance with the equipment design, the

operation of the Metrology Temperature Block may be impaired or safety hazards may

arise.

This instrument is intended for indoor use only.

BURN HAZARD

Each Metrology Temperature Block is equipped with a Block Temperature Indica-

tor (front panel LED HOT indicator – Patent Pending) even when the instrument

is unplugged. When the indicator is ashing, the instrument is not powered and the

temperature of the block is above 50°C. When the indicator is illuminated, always on,

the instrument is powered and the block temperature is above 50°C.

DO NOT turn the instrument upside down with the inserts in place; the inserts will

fall out.

DO NOT operate instrument in any orientation other than vertical (block opening face

up). Risk of re or burn hazard may result due to excessive heat build up.

DO NOT operate on a ammable surface or near ammable materials.

DO NOT touch the block access surface of the instrument.

The block vent may be very hot due to the fan blowing across the heater block of the

Metrology Temperature Block.

The calibration block temperature of the Metrology Temperature Block is the same as

the actual display temperature, for example, if the instrument is set to 700°C and the

display reads 700°C, the block is at 700°C.

The air over the block can reach temperatures greater that 200°C for high temperature

(400°C and higher) Metrology Temperature Blocks.

Probes and inserts may be hot and should only be inserted and removed from the

instrument when the instrument is operating at temperatures below 50°C.

MBXXX Series Metrology Temperature Block

Safety Information

DO NOT turn off the instrument at temperatures higher than 100°C. This could create

a hazardous situation. Select a set-point less than 100°C and allow the instrument to

cool before turning it off.

The high temperatures present in Metrology Temperature Blocks designed for opera-

tion at 300°C and higher may result in res and severe burns if safety precautions are

not observed.

ELECTRICAL HAZARD

These guidelines must be followed to ensure that the safety mechanisms in this instru-

ment will operate properly. This instrument must be plugged into a 230 VAC (115

VAC optional), AC only electric outlet. The power cord of the instrument is equipped

with a grounding plug for your protection against electrical shock hazards. It must be

plugged directly into a properly grounded receptacle. The receptacle must be installed

in accordance with local codes and ordinances. Consult a qualied electrician. DO

NOT use an extension cord or adapter plug.

If supplied with user accessible fuses, always replace the fuse with one of the same

rating, voltage, and type.

Always replace the power cord with an approved cord of the correct rating and type.

HIGH VOLTAGE is used in the operation of this equipment. SEVERE INJURY or

DEATH may result if personnel fail to observe safety precautions. Before working

inside the equipment, turn power off and disconnect power cord.

1.3.2 Cautions

To avoid possible damage to the instrument, follow these guidelines:

To properly calibrate the Metrology Temperature Block, the “Fan Limit” must be set

to “Auto.”

DO NOT leave the insert(s) in the instrument for prolonged periods. Due to the high

operating temperatures of the instrument, the inserts should be removed after each use

and buffed with a Scotch-Brite® pad or emery cloth (see the Maintenance section of

the Users Guide).

Always operate this instrument at room temperature between 5°C and 50°C (41°F and

122°F). Allow sufcient air circulation by leaving at least 15 cm (6 in) of clearance

around the instrument. Overhead clearance is required. DO NOT place the instrument

under any structure.

DO NOT interchange inserts between Metrology Temperature Block models. The in-

serts provided with the instrument as well as any additional inserts ordered are model

specic.

Component lifetime can be shortened by continuous high temperature operation.

DO NOT use uids to clean out the block. Fluids could leak into electronics and dam-

age the instrument.
