4.1 FITTING THE BATTERIES
Each gauge is supplied with 2 x AA alkaline
batteries.
To insert or replace the batteries:
1 Remove the battery cover by rotating the
retaining screw anti-clockwise.
2 Insert 2 batteries taking care to ensure
correct polarity.
3 Refit the cover and rotate the retaining screw clockwise to
secure.
The battery condition is indicated by a symbol in the top right of the
displa e more segments displayed, the better the y ( ). Th
condition of the batteries.
When no segments are displayed, it is not advisable to use the
gauge for interval logging over long periods of time (Model T only;
see Section 4.6 - ‘Setting Manual or Interval Logging’ on page en-7).
If the batteries are replaced during interval logging, the gauge may
show ‘Please Wait’ whilst it re-calculates the batch statistics.
When the batteries are nearly depleted, the battery power supply
symbol will start flashing and the gauge emits short beeps every 10
seconds to indicate that the batteries should be changed.
The gauge can also be powered via USB using the USB cable
supplied (Model T) or available to purchase as an accessory
(Model S) - see Section 15 - ‘Spares & Accessories’ on page en-21.
Note: The USB cable can not be used to charge the batteries.
4.2 SELECTING YOUR LANGUAGE

defined period of inactivity - between 1 and 10 minutes - via
Menu/Setup/Auto Switch Off.
Note: ‘Auto Switch Off’ is disabled when the gauge is powered by the USB
connection.
4.4 SETTING UP THE READING DISPLAY
The user can select up to five climatic parameters to be displayed
on screen. Measurements are taken for all climatic parameters but
only those selected are displayed. Users can select from:
RH; % Relative Humidity
Ts; Surface Temperature
Ta; Air Temperature
Td; Dewpoint Temperature - calculated from Ta and RH
TΔ; Delta Temperature - the difference between surface
temperature and dewpoint
Tdb; Dry Bulb Temperature - equal to Ta
4 GETTING STARTED (continued)
www.elcometer.com
en-5
R
Twb; Wet Bulb Temperature - calculated from Ta and RH
SH; Specific Humidity - calculated from Ta and RH
Note: The formula used for calculation of Twb and SH uses a fixed value of air
pressure set at 1.0 atmosphere (1013mbar). The accuracy of Twb and
SH will vary at other values of atmospheric pressure. This variation may
be greater than ±1°C for Twb and ±1% / 10 mbar for SH.
To setup the display:
1 Press Menu/Setup/Display/Select
Readings.
2 Use the softkeys to highlight the
required option and press ‘Sel’.
Pressing ‘Sel’ again will de-select the
option.
The gauge will beep if the user attempts to
select a parameter when five are already
selected in which case, a parameter must
be de-selected before another is chosen.
3 To select which parameter is shown in
the largest digits at the bottom of the
display, press
Menu/Setup/Display/Main Reading.
4 Use the softkeys to highlight the
required option from the list displayed
and press ‘Sel’.
Only those climatic parameters selected via Step 2 above will be available
for selection in the ‘Main Reading’ list.
To increase the size of the main reading, reduce the number of
parameters displayed on the reading screen.
Note: If a reading exceeds any set limits during measurement, it will be shown
flashing on the display, even if it has not been selected for display via
Steps 1-2 above.
4.5 SELECTING THE MEASUREMENT UNITS
a
A choice of measurement units is available ; °C, °F, g/kg, gr/lb. To
select the measurement units, press Menu/Setup/Units.
www.elcometer.com en-6
4 GETTING STARTED (continued)
R
a g/kg and gr/lb relate to ‘Specific Humidity’ measurements only.
The sensors for (a) humidity (RH) and air
temperature (Ta); and (b) surface
temperature (Ts) are located at the top of
the gauge.
Note: The surface temperature sensor is serialised
for calibration traceability purposes.
FOR ACCURATE READINGS
Do not obstruct airflow through the holes in the casing around
the humidity and air temperature sensors.
Keep fingers away from the holes - body heat can affect
readings.
Allow the gauge some time, approximately 20 minutes, to
acclimatise once it is brought from a cold environment into a
warm place and vice versa.

4.6 SETTING MANUAL OR INTERVAL LOGGING
Users can choose to manually log readings - ‘Manual Logging’
(Model S & T) or program the gauge to take readings at set time
intervals and save the readings into the batch memory automatically
- ‘Interval Logging’ (Model T only).
To select ‘Manual Logging’ in immediate mode (Model S & T):
1 Press Menu/Setup/Manual Logging.
2 To select immediate saving of a reading, use the softkeys
to highlight ‘Save only’ and press ‘Sel’.
3 To select holding of a reading followed by an option to save,
use the softkeys to highlight ‘Hold & Save’ and press ‘Sel’.
The default setting is ‘Hold & Save’.
‘Manual Logging’ is also available when in batching (Model T).
‘Interval Logging’ is only available when in batching (Model T).
For information on creating a new batch with ‘Manual Logging’ or
‘Interval Logging’, see Section 10.1 ‘Creating a New Batch’ on
page en-15.

5 THE SENSORS
a
b
www.elcometer.com en-8
R
TO AVOID DAMAGE
Do not use excessive force when measuring surface
temperature. 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
increase wear and/or damage to the sensor tip.
Do not drag the surface temperature probe over the surface to
avoid excessive wear.
The humidity sensor is fragile and should never be touched. Do
not use compressed air to clean the sensors or the gauge.
If the surface of the humidity sensor becomes saturated with
moisture, allow the moisture to evaporate fully in a dry
environment before using the gauge to take measurements.
Protect the gauge from paint dust and dirt as much as possible
as these can affect the long term accuracy of the humidity
sensor. Always keep the gauge in its protective pouch when not
in use.
Do not wash the sensors in water or with solvents.
