2.4.1 Construction
The DAT103 is a quality handheld electronic instrument built in a tough plastic field
case that fits snugly in its matching soft shockproof holster.
The front of the Analyzer includes a silicon keypad and a graphical Liquid Crystal
Display (Figure 1.1). The bottom panel has a USB PC connector and an external power
source connector (Figure 1.2). The 75-Ohm RF input on the top panel is an "F"-male
connector to which an "F" female – female adapter should be used, which makes the RF
input connector replaceable.
When you first receive your instrument, check the contents against the list provided
(Section 2.3). Check the outside of your instrument to make sure your DAT103 is free
from any signs of mechanical damage.
If the DAT103 has been stored in an extremely humid, hot or cold environment, allow it
to acclimatize for at least for 2 hours before powering up.
