1 Introduction
Thank you for purchasing a multifunctional environmental meter from PCE Instruments.
This multifunctional environmental meter combines a sound level meter, a light meter, a wind meter and a
thermometer and a hygrometer. This means, you only need one device to determine the key figures of
the environmental conditions. Due to its compact design and low weight, the environmental meter is well-
suited for measurements in the field.

5 Operation
5.1 Getting started
1. Open the battery compartment and install a 9 V battery.
2. Close the battery compartment and tighten the screw.
3. Turn on the device.
4. Select the desired measuring function.
Note:
If the battery status indication appears on the display, you should replace the battery.
You can hold the device in your hand or you can use a tripod when performing measurements.
When performing sound level measurements, the best measuring distance from microphone to
the sound source is about 1 –1.5 m.
If you want to use an external power supply, use the connection on the side of the device (see
#15 in chapter 4.1).
5.2 Switch between temperature and humidity measurements
To switch between temperature and humidity measuring, press the “TEMP/%RH” button (see chapter
4.1).
5.3 Display backlight
To turn on the display backlight, press the backlight button on the device (see chapter 4.1). Press the
button again, to turn the backlight back off. The display backlight automatically turns off after approx. 30
seconds of inactivity.
5.4 Data hold
Press the “HOLD” button once to activate the display hold function. The hold indication should now
appear and the current reading is frozen on the display. To return to the normal measuring mode, just
press the “HOLD” button again.
5.5 Select the measuring unit
5.5.1 Wind speed
To change the measuring unit of the wind speed, press the “UNITS” button when wind speed measuring
is active. You can choose between m/s, km/h, ft/min, knots and mph.

5.5.2 Light
To change the measuring unit of the light, press the “UNITS” button when light measuring is active. You
can choose between lx and Fc.
5.6 ON/OFF button
By pressing the “ON/OFF” button once, you can turn the device on. To turn the device off, you have to
press and hold the “ON/OFF” button for 3 seconds.
5.7 MODE button
If the device is turned on, press the “MODE” button to select the desired function. You can choose
between sound level, air velocity and light.
5.8 MAX/MIN recording
When in measuring mode, press the “MAX/MIN” button once to activate the capturing of the maximum
value. A “MAX” indication appears and the maximum value is shown on the display. To activate the
minimum value capturing, press the “MAX/MIN” button again. The display now shows the minimum value,
as well as a “MIN” indication. To exit the “MAX/MIN” mode just press the “MAX/MIN” button once more.
5.9 Select the temperature unit
To change the temperature unit, press the “°C/°F” button. You can choose between °C and °F.
5.10 Sound level calibration procedure
You can calibrate the device for sound level measurements by using an optional calibrator. To do so,
follow these steps:
1. Set the frequency weighting of the calibrator to A-weighting (dBA).
2. Carefully insert the microphone into the insertion hole of the calibrator (94 dB @ 1kHz).
3. Turn on the calibration and use the potentiometer (calibrat6ion screw) on the side of the device
(see #12 in chapter 4.1) to adjust the displayed value, until 94.0 dB is shown.
Note: Every device is calibrated before the delivery. We recommend a recalibration once a year.
