2. 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
14C serial number is located on the front panel below the battery compartment. Most Ludlum
Measurements, Inc. detectors have a label on the base or body of the detector for model and serial
number identification.
Important!
If multiple shipments are received, ensure that the detectors and instruments are not
interchanged. Each instrument is calibrated to specific detector(s), and is therefore not
interchangeable.
To return an instrument for repair or calibration, provide sufficient packing material to prevent
damage during shipment. Also provide appropriate warning labels to ensure careful handling.
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 “Service Department” from the drop-down menu. Then choose the
appropriate Service Department division where you will find a link to the form.
BATTERY INSTALLATION
Ensure the Model 14C range selector switch is in the OFF position. Open the battery lid by pushing
down and turning the quarter-turn thumbscrew counterclockwise a fourth 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, push down, and turn the quarter-
turn thumb screw clockwise a fourth of a turn.
Note:
The center post of a “D” size battery is positive.
