4.6 Measurement Auto Synchronise
This function allows the start of the measurements to be started in time with the clock
of the instrument.
The diagram below shows how the measurement runs from when the Start key is
pressed for the duration defined by the Run Duration when the auto-repeat function is
not activated.
This method of starting and stopping the measurements is used, for example, when the
application is Occupational Noise and the user wants to control the starting and
stopping of the measurement directly.
However, in many applications such as Environmental Noise, it is important to start the
measurements at a predetermined time. For example, when making environmental
noise measurements that are for 10 minutes, the CR:800C can be set to start the
measurements on 10 minute boundaries.
The diagram below show the measurement starts with the Auto Sync function enabled.
To enable the Auto Sync function, select the Run Duration option from the menu and
then select the Synchronise function. Use the Up and Down arrows to switch on the off
the Auto Synchronise function. Press Exit when finished.
