Getting Started
Unpacking and Repacking
Remove the calibration certificate and place it in a secure location. Remove
the instrument and accessories (batteries, cable, etc.) and ensure that all of
the items listed on the packing list are in the carton. Check individual item
serial numbers and ensure calibration certificates match. The Model 5 serial
number is located on the front panel below the battery compartment.
To return an instrument for repair or calibration, provide sufficient packing
material to prevent damage during shipment.
Every returned instrument must be accompanied by an Instrument Return
Form, which can be downloaded from the Ludlum website at
www.ludlums.com . Find the form by clicking the “Support” tab and
selecting “Repair and Calibration” from the drop-down menu. Then choose
the appropriate Repair and Calibration division where you will find a link to
the form.
Battery Installation
Ensure the Model 5 range selector switch is in the
OFF
position. Open the
battery lid by pushing down and turning the quarter-turn thumbscrew
counterclockwise a quarter of a turn. Install two
˝ D ˝
size batteries in the
compartment.
Note the (+) and (-) marks inside the battery door. Match the battery
polarity to these marks. Close the battery box lid, and then push down and
turn the quarter-turn thumb screw clockwise a quarter of a turn.
Note:
The center post of a “D” size battery is positive.
