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.

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

 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 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)

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’.

5 THE SENSORS

www.elcometer.com en-8

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.

5 THE SENSORS (continued)
