PREPARATION FOR USE

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.

POWER SUPPLY

The instrument is supplied by 1x9V alkaline battery type IEC 6F22 included in the package. Battery life: about 200 hours. When the battery is low, the symbol “ ” appears on the display. Replace it immediately, following the instructions given in § 6.2.

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).

FUNCTION KEY DESCRIPTION

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).

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.

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.

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.

°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:

so: 0°C is equal to 32°F, 100°C is equal to 212°F

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 the display
3. Repeat the same operation of points 1 and 2 to enable the function again. This function is automatically restored after each shutdown

OPERATING INSTRUCTIONS

AIR TEMPERATURE AND HUMIDITY MEASUREMENT

CAUTION: Do not perform measurements in humid environments. Do not perform 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
4. Press the HOLD/ key to freeze the result on the display (see § 4.3.2)
5. Press the MAX MIN key to read the Maximum or Minimum values on the display (see § 4.3.3)
6. Press the WB/DP key in order to show the wet bulb or dew point temperature values (see § 4.3.4)
7. Switch off the instrument after measurement
