2. GENERAL DESCRIPTION
The instrument has the following functions:
Air temperature measurement with integrated sensor
Relative humidity (%RH) measurement with integrated sensor
Dew point temperature measurement
Wet bulb temperature measurement
MAX MIN function
Data HOLD
Backlight
Auto Power OFF
Each function can be selected via the corresponding key. The selected quantity appears
on a high-contrast display with indication of measurement unit and of the active functions.
The instrument is also provided with function keys, for their use please see § 4.2.
3. PREPARATION FOR USE
3.1. INITIAL CHECKS
The instrument has been checked from every point of view before shipment. Every care
has been taken to make sure that the instrument reaches you in perfect conditions.
However, it is advisable to make a rapid check in order to detect possible damages, which
may have occurred in transit. Should this be the case, please immediately enter the usual
claims with the carrier. Make sure that all the accessories listed in § 7.3 are contained in
the package. In case of discrepancies, please contact the dealer. In case the tester needs
to be returned, please keep to the instructions given in § 8.
3.2. POWER SUPPLY
The instrument is supplied by 1x9V alkaline battery type IEC 6F22 included in the
package. Battery life: about 200 hours. When battery is low, the symbol " " appears
on the display. Replace it immediately, following the instructions given in § 6.2.
3.3. STORAGE
In order to guarantee the accuracy of the measurements, after a period of storage in
extreme environmental conditions, wait for the necessary time so that the instrument
returns to normal measuring conditions (see § 7.2.1).

4.3. FUNCTION KEY DESCRIPTION
4.3.1. ON/OFF key
Press the ON/OFF key to switch on and off the instrument. The ON/OFF key also allows
enabling/disabling the Auto Power OFF function (see § 4.3.6).
4.3.2. HOLD/ key
By pushing HOLD/ key the value measured by the instrument is frozen on the display
and the symbol “Hold” appears on it. Press the HOLD/ key again to disable this function
and resume normal operation. Press and hold the HOLD/ key for at least 1s to
enable/disable the display’s backlight.
4.3.3. MAX MIN key
Press the MAX MIN key permits to detect the Maximum or Minimum values in the “°C”,
“°F”, “%RH”, “WB” and “DP” functions. The display shows the symbol associated with the
selected function: “Max” for maximum value and “Min” for minimum value. Both values are
constantly updated and are displayed cyclically every time the same key is pressed. Long
pressing the MAX MIN key allows quitting the function.
4.3.4. WB/DP key
Press the WB/DP key to enable/disable the Dew Point (DP) and Wet Bulb (WB)
temperature measurement used in buildings and meteorology applications.
4.3.5. °C and °F keys
Press the °C key to select the “Celsius” temperature measurement unit or the °F key to
select the “Fahrenheit” temperature unit. The keys are disabled if the function “HOLD” is
activated.
The formulas for the conversion between Celsius and Fahrenheit degrees are:
T [°C] = 1.8 32-F][T or T [°F] = T [°C] * 1.8 + 32
so: 0°C is equal to 32°F, 100°C is equal to 212°F
4.3.6. Disabling the Auto Power OFF function
The instrument is provided with an Auto Power OFF (APO) feature which automatically
allows switching it off after 15 minutes of idleness, in order to preserve the internal battery.
To disable this feature please follows the steps below:
1. With the instrument on, press and hold the °C key
2. Press the ON/OFF key. The “ “ symbol (see Fig. 2 – part 10) disappears from display
3. Repeat the same operation of the points 1 and 2 to enable the function again. This
function is automatically restored after each shutdown

measurements in presence of explosive materials or combustible gases or in
dusty environments. Do not expose the integrated sensor to high mechanical
stress
1. Turn on the instrument by pressing the ON/OFF key
2. Select the temperature measurement unit (see § 4.3.5)
3. Position the integrated sensor (see Fig. 1 – part 1) in the test area. The real-time
temperature value is shown on the main display (see Fig. 2 – part 6) while the real time
relative humidity value (% RH) is shown on the secondary display (see Fig. 2 - part 8).
The "OL" value indicates that the maximum measurable values have been exceeded
