1 ABOUT YOUR GAUGE
The Elcometer 319/2 Dewpoint Meter is used to check climatic conditions in the surface treatment industry.
The gauge measures the following parameters:
• Surface temperature
• Air temperature
• Relative humidity
From these measured values, your gauge then calculates:
• Dewpoint temperature
• Delta T (∆T)
The Elcometer 319/2 Dewpoint Meter has readings memory and an internal clock. This allows
measurements and a date/time stamp to be stored as they are taken.


3
In order to document the climatic conditions during a coating job, the Elcometer
319/2 Dewpoint Meter is equipped with two types of internal memory. The
memory for manual logging can store up to 6000 records in a maximum of 8
batches. The memory for interval logging can store up to 12 000 records in a
maximum of 8 batches.
Data can be evaluated on screen or exported to a PC using the optional
Elcometer 319/2 Dewpoint Meter Dock. This optional accessory can also be
used to measure surface temperature using an external temperature sensor.
1.1 CLIMATIC CONDITIONS
The risk of condensation forming on surfaces about to be coated is always
present and is difficult to assess without suitable instruments. In particular, it is
difficult to detect condensation on blast cleaned surfaces.
Surfaces with a temperature at or below the dewpoint temperature will be
covered with condensation/moisture.
It is important to take measurements at regular intervals and at different points
on the surface. Factors like sun, shadow, the shape and the mass of the object
to be coated can create unexpected thermal behaviour on the surface.
The memory in your Elcometer 319/2 Dewpoint Meter can be used to record
climatic conditions during a coating job.

3 GETTING STARTED
3.1 FITTING BATTERIES
Your gauge is powered by three batteries. The condition of the
batteries is indicated by a battery status symbol [ ] displayed on
the measurement screens. The more segments displayed, the better
the condition of the battery. When the battery is low, the symbol starts
blinking to indicate that the batteries have to be changed. The battery
status is also displayed in the SETUP menu - scroll to Device info and
then press OK.
To save the time and date settings, the batteries must be exchanged
within 30 seconds, however readings data in the memory is not
affected by removal of the batteries. Always check the time and date
after replacing batteries.
Use high quality batteries only.
Alkaline batteries must be disposed of carefully to avoid
environmental contamination. Please consult your local
Environmental Authority for information on disposal in your region.
Do not dispose of any battery in fire.

3.2 WHAT THE BUTTONS DO
Press the LIGHT button to switch the light on and off. The light illuminates the surface being measured and
switches off automatically after approximately 40 seconds.
The display backlight illuminates after pressing any of the buttons on the keypad and switches off after
approximately 16 seconds. This function can be disabled - see “Backlight on” on page 20.
When the gauge is not being used, it will switch off automatically after approximately 120 seconds of
inactivity.

3.3 THE SENSORS
The sensors for humidity, air temperature and surface
temperature are located in the casing at the top of the gauge.
For accurate readings:
• Do not obstruct airflow through the slots in the casing around
the humidity and air temperature sensors.
• Keep your fingers away from the slots - the heat from your
body may affect readings.
• Allow the gauge some time to acclimatise once it is brought from a cold environment into a warm place
or vice versa.
To avoid damage:
• When measuring surface temperature DO NOT USE EXCESSIVE FORCE! A light contact between
the probe and the surface is sufficient. Using force does not increase the measuring speed or improve
the accuracy of the measurement, but it does wear and/or damage the sensor tip.
• Do not drag the surface temperature probe over the surface.
• Although the humidity and air temperature sensors are equipped with an integrated dust filter, it is
recommended to keep the gauge away from paint dust and dirt as much as possible.

8 GAUGE SET UP
From MENU, scroll to Setup and press OK to configure and view the following set up options:
8.1 INTERVAL
Interval is the time period between measurements during automatic logging (Log
interval).
Each interval time (10s, 1m, 2m, etc.) is paired with the number of days the
measurements can be logged, taking into account the amount of free memory and
the interval time.
The total battery power remaining (% full) and the amount of free memory (% free) is
also displayed.
When a critical logging time is set, the message Low battery will be displayed instead
of % full. This means that the logging period cannot be fully used due to a lack of
battery power. Note that the gauge retains the data even if the batteries are empty.
You may need to change the batteries or change the interval time to be able to
complete interval logging.
