Notes have been activated. Refer to User Manual for more details.

Run Screens

The Play symbol is displayed at the top left-hand corner of the screen, and the

Pause symbol is displayed at the bottom left-hand corner of the screen. The lefthand soft key ( ) is the Pause/Run control and toggles between these two modes when operated.

when measurements are paused. The incremental run number and its duration are displayed at the top right-hand corner of the screen. If the Run Duration Timer is set, an icon that shows a stopwatch is displayed next to the countdown timer. To enable or disabled the Run Duration Timer, use the Settings screens (refer to Figure 6). If the Run Duration Timer is not set, the digital timer clock counts up until you stop the measurement run manually (by pressing the Run/Stop

Taking Measurements

(Refer to Figure 10)

The measurement options and screen details will vary, depending on the instrument type you are using.

The instrument must be in the Measurement Stop mode (with red bars at the top and bottom of the screen) before you can start a measurement.

Press the Run/Stop key ( ) to start making measurements. The screen shows green bars at the top and bottom.

Figure 11. Graph and Main screens

For instruments that include this option, the broadband values can be viewed as a bargraph or as a graphical time history on the Graph screen. Press the View key ( ) to toggle between the Graph and the Main screens.

Certain instrument types provide two additional Octave (or 1/3 Octave) screens (refer to Figure 12). Use the View key ( ) to toggle the screens. Use the left/right navigation

Each bar in the graph represents an octave band measured in Hz or kHz. To view a table of the octave values, press the View key ( ).

In 1/3 Octave mode, use the up/down navigation keys to change the displayed frequencies on the table.

Some instruments in the CEL-63x range can display all the screens shown in

Figure 11 and Figure 12.

The Marker screen allows you to tag noise data and record audio, for example noise

When the measurement run has finished, press the Run/Stop key ( ). A screen is displayed asking you to confirm the action - press Yes to end the run.

Storage

Switch the CEL-63x instrument off when you are not using it to record measurements, and remove the batteries if the instrument will not be used for extended periods of time.

Always protect the instrument from physical damage and from water.

To protect the microphone, you should always keep the windshield fitted.

Introduction

This Quick Start guide helps you to familiarise yourself with the CEL-63x instrument quickly, so that you can begin to use it without delay.

The guide assumes this is the first time you have used the instrument. It therefore includes instructions to install the batteries, switch ON and set up the instrument to be ready for use, calibrate it, take measurements, and store it safely.

We want you to get the best possible performance from the CEL-63x instrument, and we recommend you refer to the Operator’s Manual for detailed information.

Think Environment. Think Casella.

Fit the batteries

The CEL-63x instrument requires three AA batteries.

Remove the battery compartment cover and fit the batteries using the correct polarities. Refit the battery compartment cover.

Note: The batteries can be zinc carbon, alkaline or rechargeable. DO NOT mix battery types.

Switch the instrument ON

Press the On/Off key. Confirm the battery condition symbol shows there is a good level of charge in the batteries.

The initialisation screen is displayed for approximately 10 seconds, and then the measurement screen is displayed in the STOP mode (with red bars at the top and the bottom of the screen). Press the Menu key to access the settings, memory and instrument status. The screens displayed depend on the model of instrument in use.

Measurement data sets

(Refer to Figure 7)

Cumulative measurements made by the instrument apply for the entire measurement duration. They do not show how the sound level changed during the period of measurement. The instrument can also make Periodic measurements, which store measurements acquired during a repeating interval of time. When one interval ends, the next one begins until the periodic measurements stop.

The instrument’s Profile recording function provides an additional time-history recording channel, which may operate in parallel with either Cumulative or Periodic data recording. The Profile time history channel can provide faster recording resolution but for a reduced set of noise parameters.

Select Settings and use the navigation keys to select the Measurement control
