SAFETY PRECAUTIONS(Be sure to read these precautions before using our products)

Warning

Procedures which may lead to dangerous conditions and cause death or serious injury, if
not carried out properly.

CautionProcedures which may lead to dangerous conditions and cause superficial to medium
injury or physical damage or may degrade or damage the product, if not carried outproperly.

Warning• Temperature sensor (hereinafter sensor) for the DFT-700 is designed to measure thetemperature. Never use the sensor other than for measuring temperature.
• Never use sensors on the human body such as taking temperature.
• Adjust the DFT-700-M input specification to its sensor type. If it is not adjusted, a correct
measurement value cannot be obtained. [The sensor type is written on the code terminal(e.g. K, Pt100) with its maximum measurable temperature.]• Do not use the temperature sensor for measuring the surface of objects, liquids and theinside of objects, still or rotating objects or as the sensor for the surface of moving orrotating objects. It may lead not only to the malfunction and damage of the sensor, but itis also hazardous.
• When measuring an object through which current is running, a correct measurement
value cannot be obtained, since the temperature sensing section is grounded.
• Do not touch the temperature sensing section or protective tube just after measuring,
because it may lead to burns, frost bite or other injuries.

1Caution• The temperature indicated on the code terminal is the high limit temperature of the sensing
section. Use the grip, cord, etc. in normal atmospheres (0 to 60 ) with the exception of thesensing part. Using them in high temperature atmospheres may lead to malfunction or ignitionof the sensor.
• The grip of the sensor is not waterproof.
• When measuring under -50 , sensors become less flexible and may easily break.
• Do not use the sensor at a location where there is electric noise such as strong magnetic fieldor high frequencies. The DFT-700-M and sensor may be damaged.
• Do not use the sensor in an atmosphere where there are corrosive substances such as acidor alkali, as they may degrade or cause malfunction.
• Do not cool rapidly by soaking the sensing section in water right after measuring hightemperature. Otherwise, the sensor will malfunction.

Using the temperature sensor on the surface of an object: PCE-701• Error through incorrect positioning
If the sensor is not used in the correct position, a correct
measurement value cannot be obtained.
Contact the temperature sensing section to the surface ofthe measured object so as not to leave a gap between them.
• Condition of the surface of the object
Surface of the object
When the surface of the object is not clean, measurement
errors may occur. Clean the surface before measurement.
(Make sure to clean the surface when its temperature is safe.)
When the surface is not flat, measurement errors may occur.
Measurement errors differ depending on the characteristics of the surface of the object.
In order to decrease measurement errors, measure as flat a surface as possible.
• Contact pressure to the surface of object
When contact pressure to the surface is sufficient, heat transition from the surface to thetemperature sensing section is smooth and measurement errors tend to be small.
But when excessive pressure is given to the surface, it may scratch the surface, deform or
break the temperature sensing section of sensor.
(Do not apply excessive tension beyond the capacity of the spring-like temperature sensing
section of the sensor.)2

Using the temperature sensor for the surface of a rotating object: PCE-702• Error through incorrect positioning
If this sensor is not used in the correct position, correct
measurement values cannot be obtained. Contact thetemperature sensing section to the surface of themeasured object so as not to leave a gap between them.
When the surface of object is rotating, errors may occur
as a result of frictional heat.
Direction of rotation• Condition of the surface of the object
When the surface of object is not clean, measurement errors may occur.
Clean the surface before measurement. (Make sure to clean the surface when its temperature
is safe.)When the surface is not flat, measurement errors may occur.
Measurement errors differ depending on the characteristics of the surface material of the object.
In order to decrease measurement errors, measure as flat a surface area as possible.
When measuring the surface of a cylindrical object, the contact area of the temperaturesensing plate differs depending on its radius. The smaller the radius is, the larger themeasurement errors tend to be, because the contact area is small.
When measuring the surface of a rotating object, do as the above graphic indicates.
Do not measure the temperature of an object when the direction of rotation is opposite, slantor vertical. This is dangerous, and the sensor may malfunction or break.
• Contact pressure to the surface of measured object
When contact pressure on the measuring surface is sufficient, heat transition from the surface
to the temperature sensing section is smooth and measurement errors tend to be small.
But when excessive pressure is given to the surface, it may scratch the surface, deform or
break the temperature sensing contact plate of the sensor.

Using the temperature sensor on the surface of a still object: PCE-707, 707L, 700M

• Error through incorrect positioning
If the sensor is not used in a correct position, a correct
measurement value cannot be obtained.
Measure the temperature of the object by placing the sensor on thesurface vertically. A slight slant affects the measurement value
and causes error.
Do not move the sensor while it is pressed and touching theobject surface. The temperature sensing section (Ribbon)
might be defaced or damaged.
• Condition of the surface of the object
When the surface of the object is not clean, measurement
errors may occur. Clean the surface before measurement.
(Make sure to clean the surface when its temperature is safe.)

the surface of measured object. In order to decreasemeasurement errors, measure as flat a surface as possible.
Surface ofAs this sensor is used for the surface of still object, it cannot
the object
measure the surface temperature of moving or rotating object.
Never measure the surface of moving or rotating object because
it is hazardous and may damage the sensor.
• Contact pressure to the surface
This sensor is designed to prevent its temperature sensing section (Ribbon) from excessive
contact pressure by attaching a ring which acts as protection against deformation and damage
to the temperature sensing section (Ribbon).
Such being the case, be sure to measure the temperature of objects that are bigger than thering. Otherwise, the surface may be scratched, or the temperature sensing section (Ribbon)
may deform or break.
• Temperature sensing section (Ribbon)
While this sensor excels in responsiveness with an exposed temperature sensing section(Ribbon), it is a delicate instrument.
Responsiveness becomes worse and measurement errors occur as a result of the temperaturesensing section (Ribbon) deformation caused by long term or inappropriate use of the sensor,
dropping, hooking, or pressing the measured part with fingers.

Once the temperature sensing section (Ribbon) is deformed, it is impossible to repair.
So be careful when handling.

Thermocouple for replacement (sold separately): PCE-H7

Thermocouple for replacement (hereinafter PCE-H7) is exclusively
for the use of the PCE-707 and PCE-707L.
• How to exchange PCE-H7 for a new one
When replacing PCE-H7 with a new one, pull the PCE-H7 out fromthe sensor holding the ring and plug. Then insert the Plug pin into
the socket of the sensor holding the Ring and Plug of the newPCE-H7. (Never touch the Plug pin or Ribbon.)• Refer to the Temperature sensor for the surface of still objects,
for the explanation of “Error through incorrect positioning”,“Condition of the surface of the object”, “Contact pressure tothe surface” and “Temperature sensing section (Ribbon)”.

RibbonUsing the temperature sensor for liquids and the inside of an object: PCE-704,PCE-706, PCE-709, PCR-701• Insertion error
The sensors include a temperature sensing element in a protective tube.
In order to measure temperature with less error, insert it into the object to thedepth 10 times or more longer than the protective tube diameter.
When the insertion depth is not sufficient, measurement errors become large.
Apart from the above, when RTD (PCR-701) is used as a temperature sensing
element, secure a 50mm length or longer for insertion.
• Protective tube
Among the sensors, some of them have a protective tube with a sharp tip, socare should be taken when handling.
Do not use excessive force to the protective tube, and do not bend, as thetemperature sensing element will be damaged.
