NEVER allow the slings to contact the electronics enclosure. Damage to the enclosure
may occur. If the slings do come in contact with the electronic enclosure then remove
the two bolts holding the enclosure to its base and temporarily remove the head from
the meter during the lifting operation. You will need to unplug the cable from J3 on the
Acquisition Module. Two screws hold this cable in place.
