Our condition monitoring sound level meter records and visualizes sound levels in the range from 30 to 130 dB. It has three manual measuring ranges and an automatic measuring range mode. When the device is switched on, the automatic mode with a range of 30 to 130 dB is activated by default. The manual ranges are 30 to 90 dB, 50 to 110 dB and 70 to 130 dB.
The user can choose between the frequency weightings A and C and between the time weightings "Fast" and "Slow" at the touch of a button. Before the recording mode can be started, the condition monitor must be connected to a PC via a micro USB port and the parameters configured using the PC software. The storage interval, the number of measured values and also the starting point of the condition monitoring sound level meter can be set. Up to 32000 measured values can be recorded with this function. The interval can be set on the condition monitoring sound level meter in steps from 1s to max. 24h.
The condition monitoring sound level meter has the MIN, MAX and HOLD functions. In addition, the device switches off automatically after about 3 minutes of inactivity to extend the operating time of the battery. The "Auto Power Off" function can also be deactivated.
