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.
