1. Introduction
This manual is designed to introducing with the instrument, principle
of action and operation rules of Dew Point Meter NOVOTEST KTR1, hereinafter the Device.
2. Appointment
2.1. Dew Point Meter NOVOTEST KTR-1 is designed for rapid nondestructive measurement the temperature, humidity, dew point
calculation and measurement the surface temperature by contact
method.
2.2. Dew Point Meter NOVOTEST KTR-1 allows user to measure:
– air temperature (-20 to + 125 ° C)
– surface temperature (-20 to + 125 ° C)
– relative humidity
and calculates:
– dew point temperature
– difference between dew point and surface temperature
2.3. The Device can be used in workshop, laboratory, “field
conditions”, at high-altitude objects and in other environments
according to the rules of safety at ambient temperatures from -10 °
C to + 40 ° C and relative humidity up to 100%.

5.2. The Device placed in the package (case) for storage and
transportation.
6. Safety precautions and maintenance
6.1. The humidity sensor is very sensitive and should not be
subjected to the touch.
Do not expose NOVOTEST KTP-1 long heavy loads and extreme
temperatures. Overheating can damage the screen, plastic housing
and internal parts.
Dust and prolonged high humidity can damage the unit, causing
malfunction. The device is not water resistant and can not be
immersed in liquid.
Plastic surfaces may be cleaned only with isopropyl alcohol
(ethanol) and dried with a soft cloth. Other solvents may cause
damage to the plastic housing.
6.2. Maintenance of device made by the manufacturer in case of
trouble.

- Press and hold leads to on / off the device.
- Control of button illumination. Long pressing leads to
overturning on 180 degrees the information at the display.
- On / off of displaying of all measured parameters.
- Selecting the measurement mode.

7.3. The battery status
3 segments indicate battery status. The larger number of displayed
segments, the more energy remains in the battery. When low energy
level, the battery symbol starts to blink, and the battery should be
charged. Connector for charging is located in the upper end of the
unit.
8. Operating
The device measures the three different values: air temperature,
surface temperature and relative humidity. From these values shall
be calculated dew point temperature and ΔT.
8.1. Relative humidity
For the accurate measurement of relative humidity is necessary to
ensure unimpeded air flow through the grooves of the sensor.
8.2. Surface temperature
The sensor for measuring the surface temperature has a metal tip.
Metal tip is placed against the surface, preferably at an angle of 90
°, and fixed in this position until the stabilization of the measured
values. During measuring user needn’t press on the Device with a
great force.
8.3. Air temperature
The sensor measures the temperature of the air directly in their
environment, and so it is important to keep items which could affect
on the temperature of the air, for example, the fingers away from this
sensor.
8.4. Dew point temperature
Dew point temperature is calculated parameter which is obtained
from the values of air temperature and relative humidity.

Surfaces with surface temperature near or below the dew point
temperature will be covered by condensate.
8.5. ΔТ
ΔT - is the difference between the surface temperature of tested
objects and the dew point temperature.
8.6. The warning signal
Devices makes sound alarm when ΔT (difference between surface
temperature and dew point) decreases more than 3 ° C. In such
climatic conditions there is a risk of poor-quality painting, due to the
formation of condensation on the surface. A warning signal sounds
only in the mode of displaying difference between the surface
temperature and the temperature at point.
9. Storage and transportation
9.1. The Device must be stored at ambient temperature from -10 to
+35 ° C and relative humidity up to 80% at 25 ° C.
9.2. The storage should be free of dust, fumes, acids, alkalis and
corrosive gases.
9.3. Transporting device in a package can be made by any mode of
transport in accordance to the requirements and rules of
transportation, operating on the data types of transport.
9.4. During transportation, handling and storage of stock unit should
be kept from blows, shocks and moisture.
