- The display shows the measured sound level in dB(A) (according to valuation curve
A).
If the display shows "OVER", the value is higher or lower than the selected measu-
ring range.
By pressing the "SELECT" key you can switch to the next higher measuring range
("HI"). By pressing once again you can change the valuation curve
(LO A -> HI A -> LO C -> HI C -> LO A etc.)
LO = 35 dB up to 100 dB
HI = 65 dB up to 130 dB
- After the measurement switch off the device by pressing the green key.
Measuring the Air Humidity
The air humidity measurement is intended for comparative measurements for the
domestic use and is not appropriate for the professional use.
Only perform the measurement in a range of 25% up to 95% (not condensing).
Proceed as follows:
- Switch the measuring range selector switch (5) to position
"%RH".
- Now position the air humidity probe (2) in the area to be mea-
sured (please observe the operating data of the measuring
instrument).
You can obtain the best measuring results, if you leave the
probe in the area to be measured for approx. 6 min.
- The display shows the measured relative air humidity in %.
- After the measurement switch off the device by pressing the
green key.
Measuring the Temperature
The temperature measurement is intended for comparative measurements for the
domestic use and is not appropriate for the professional use.
By means of the enclosed K-type temperature sensor you can measure directly tem-
peratures in the range of –20°C up to +750°C in 2 measuring ranges. The temperatu-
re to be measured must only be applied to the tip of the metal probe.
