16.6 Setting Up 2-channel Logging and Enhanced Logging

1) Select:

– The 2-Ch. Logging SLM project template for logging broadband data only from the

two inputs

– The 2-Ch. Logging project template for logging both spectra and broadband data from

the two inputs

– The 2-Ch. Enh. Logging project template for logging both spectra and broadband data

from the two inputs, making reports and periodically saving the data on the memory

card.

Note: 2-Ch. Enh. Logging is not available for hardware versions 1–3.

The project template is displayed at the top of the screen, if it does not display the correct

template tap the Project Template Bar at the top of the screen and select the correct

template from the drop-down menu. (See section 3.3.1 for more details on templates.)

2) Tap the Main Menu icon .

3) Select

– Setup > Frequency Settings to set Broadband frequency weighting parameters,

as required

– Setup > Statistics to set statistics parameters, as required

4) Set the parameters you want to log every 100 ms in Logged Broadband (100 ms).

You can specify up to 4 parameters from the two channels.

5) Set the broadband parameters you want to log in Logging Broadband.

You can either log all parameters from both channels or select up to 10 parameters from

the two channels. The fewer parameters you select the less space will be needed for saving

on the memory card.

6) Set the spectrum parameters you want to log in Logged Spectrum.

You can either log all spectrum parameters from both channels or select up to four

spectrum parameters from the two channels.

7) Set the Level Trigger parameter(s) as required.

You can level trigger on a parameter from either Ch.1 or Ch.2.

8) Tap to exit Setup.

Note: You should select the transducers before selecting the parameters to log and selecting the

level trigger parameter(s). Changing the transducer afterwards might correct the selected

parameter; e.g., if you have selected to log Ch.1 LAeq and change the transducer at channel 1

from a microphone to an accelerometer, then the Ch.1 LAeq will not be available anymore and

the parameter will be set to Off.
