MOISTURE PROTECTION
Full Electronic Scales have been designed to provide protection from the effects of
moisture.
• The load cells are calibrated with the cable attached.
• The cable
MUST NOT be cut.
• The cable is connected directly to the Junction Box through a sealed bushing
which MUST BE TIGHTENED WITH PLIERS to keep moisture out of the box.
• On all boxes, the black plastic fittings have O-rings that can be forced out of
position if the bushing itself is not tight.
─ To prevent this, first tighten the inner nut securing the bushing in the hole.
─
Then insert the cable and carefully tighten gland with pliers until it is very snug.
─
DO NOT over-tighten where bushing 'turns'.
─
All box covers MUST BE SECURED with ALL screws tightened properly ( 18
to 20 lbs/in ) for protection against moisture.
