4.1 Unpacking and Repacking
Remove the calibration certificate and place it in a secure location. Remove the instrument
and ensure that all of the items listed on the packing list are in the carton. Check individ-
ual item serial numbers and ensure calibration certificates match between instruments and
detectors (if applicable). The serial number is located on the side of the unit.
To return an instrument for repair or calibration, provide sufficient packing material to pre-
vent 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 "Service Department" from the drop-down menu. Then choose
the appropriate Service Department division where you will find a link to the form.
4.2 Battery Installation
A low-battery indicator appears on the top of the LCD when less than 24 hours of battery life
remain. Follow these steps to replace the two standard AAA batteries:
1. Disconnect HV cable and remove from mount.
2. Turn the instrument over so that the back of the instrument is facing up.
3. Use a flat-bladed screwdriver to completely loosen the single captive screw on the
battery cover.
4. Release and remove the battery cover.
5. Install two new AAA batteries following the symbols on the bottom of the battery
compartment.
6. Replace the cover and tighten the screw.
