avoided.

This denotes dangers which COULD result in minor personal injury and/or product or

property damage, if not avoided.

[Safety precautions]

WARNING

z Do not use this unit for medical applications, such as body temperature measurement of a person or an animal.
z Do not touch the sensor immediately after the high temperature or low temperature part has been measured.

Otherwise, burn damage may occur.

z Do not measure any object which is charged with electricity not to cause an electrical shock.
z Do not use this unit for measurement other than the specified.

CAUTION

z Do not use any battery or power supply unit other than the specified one.

Otherwise, fluid leak or explosion may occur, and malfunction or personal injury may result.

z Do not measure temperature beyond the specified measurement range not to cause the unit to malfunction or to be

damaged.

z Never attempt to disassemble or modify this unit.
z Use always the parts specified by OMEGA ENGINEERING, INC. on the replacement of any parts or expendables.
z Do not put any foreign object in the sensor insertion port, external power supply port, or communication port. Otherwise,

an electrical shock, a fire, or other damage to the unit may occur.

z Do not operate or store this unit in a place where it is exposed to the direct sunlight or the temperature is high.

Additionally, do not leave this unit in a place where the high temperature continues for an extended period of time, such
as inside of a car. Otherwise, the discoloration or the deformation may occur on the unit.

z If the battery cover is removed with the main unit getting damp, the water may enter the unit.

Before replacing the batteries, dry the main unit completely.

z In addition to the main unit, on the handling of any accessories to be connected to the main unit,

follow always the safety precautions stated in this manual.

OMEGA ENGINEERING, INC. shall not be held responsible for any defect arising from
negligence of such cautions and instructions.

z Any relevant measures for safety such as sufficient tolerance and failsafe means shall be taken into

consideration when using this unit for an application that may seriously affect the human life or
property.

II

 Handling precautions

z Connect “special connector” or “thermocouple miniature connector” applicable to “ASTM

E1684-96 Standard Specification for Miniature Thermocouple Connectors” to the connector port.

Otherwise, malfunction may occur.

z Do not put any foreign object inside the connector port. Otherwise, malfunction may occur.

z Lock the battery cover firmly after the replacement of the batteries.

If the packing of the battery case is not in place or if any dust is caught in, the leakage of water may
occur.

z Store it with the batteries removed if this unit is not used for a long period.

Otherwise, the leakage of battery fluid may occur and cause the main unit to malfunction.

z If a battery is swallowed, serious personal injury may be caused.

Put and keep batteries carefully in a safe place where a child cannot get access to them.

z Observe strictly the cautions stated on the batteries to handle correctly them.

z Replace all of four AA batteries with new ones immediately if the low battery alarm occurs (see

section 1. Starting up).

z The service life of the battery may vary depending on the service conditions or the brand of the

battery.

z Do not press the display panel or keypad strongly. Otherwise, the display panel or keypad may

break.

z Do not drop the unit or apply any strong impact to it as it is a precise instrument.

z Do not operate this unit under the water.

z Keep this unit away from any equipment producing the strong static electricity or electromagnetic

wave, such as television set, microwave oven, or radio receiver as much as possible.

Otherwise, malfunction or trouble may occur.

z Keep this unit away from any equipment producing the strong high frequency or surge as much as

possible. Otherwise, malfunction or trouble may occur.

z Wipe it off lightly with a cloth, which is wrung out with neutral detergent, to clean this unit.

Do not use any solvent, such as benzene, paint thinner, or alcohol, or bleach at any case.

z This unit has a washable structure (protection grade IP64).

However, if the unit is left with the water splashed for a long time, the water may enter the unit.

Wipe off the unit with a dry cloth rag as soon as possible after washing.

z Mount the connector covers, the plug-covers, and battery cover firmly whenever washing.

z Remove the dirt or water content sticking to the sensor or main unit completely, and store them

safely after the measurement.

z Do not operate or store the main unit in a place where the temperature becomes −20℃ or less or

55℃ or more, or the relative humidity becomes 90% or more.

z Do not operate or store the unit in an environment where there are direct sunlight, or fine particle

dust, or high temperature and humidity, or any corrosive ingredient.

z Contact your nearest sales representative or sales office for any after-sale service such as repair.

z Do not stick the sensor protector to a hard substance. Otherwise, the sensor protector may be broken

or bent. Do not bend the protector intentionally. Never use the bent sensor.

z Do not stretch the sensor cable strongly.

Otherwise, the breakage of wiring and malfunction may occur.

III

z Do not use a sensor with any deterioration or damage.

Otherwise, the temperature may not be measured correctly.

z Insert the measurement part of the probe into a substance by 50% of its length when using a

needle-type one.

The excessive insertion may cause burn damage and the probe to be damaged by the heated-up grip

z Use always the probe grip and the connection cable within the specified temperature range.

The heat resistance of such part is low in comparison with the measurement part of the probe
(metallic portion).

z The sheath thermocouple wire is intended for the fixed wiring.

Avoid the winding, the twist, the stretch, friction and vibration for the wire repeatedly not to cause
the wiring or the insulator to be damaged or to be deteriorated.

z Log mode

In the log mode, the data can be recorded until the total number of data recorded to 20 logs reaches

40000.

One number of data corresponds to the data volume used for one recording at one channel.

Therefore, the number of data to be recorded may vary depending on the number of channels to be
used.

The available recording cycles is calculated from the following formula.

Available recording cycles [cycles] = Free memory capacity [data] ÷ Number of channels in use

[ch]

The available recording time is calculated from the following formula.

Available recording time [time] = Number of remaining cycles [cycles] × Recording interval

[time]

[Example]

If the free memory capacity is “1000”, all of four channels are used, and data is recorded at intervals of
5 min., the available recording time is 1250 min.

1000 (free memory capacity) ÷ 4ch (number of channels in use) × 5 min. (recording interval) = 1250
[min]

z Tag mode

In the tag mode, the data can be recorded until the total number of data recorded to 20 tags reaches

10000.

One number of data corresponds to the data volume used for one recording at one channel.

However, the number of data to be consumed may vary depending on the number of channels in use.

[Example]

If the free remainder of memory capacity is “1000” and the data is recorded using three channels, up to
647 data records can be recorded.

1000 (free memory capacity) × 11÷17 (coefficient) = 647 [data]

Available recording cycles = Free memory capacity [data] ×11÷11
Available recording cycles = Free memory capacity [data] ×11÷14
Available recording cycles = Free memory capacity [data] ×11÷17
Available recording cycles = Free memory capacity [data] ×11÷20
