5. Cover the meter face with padding to protect
the glass window. Wrap the housing and place
it in the same container as the wattmeter.
6. Because of the size and weight of the wattme-
ter it is recommended that the wattmeter then
be packed and braced in a sturdy wooden crate
for shipment.
Storage
If it should become necessary to store the wattmeter for any
length of time, no special preparation is necessary. The vent
plug is designed to normally remain closed and therefore no
coolant should evaporate during even lengthy storage. The
connector should be wrapped and sealed to prevent dirt
from entering. It is also suggested that the load housing be
covered to prevent the accumulation of dust on the cooling
fins. The storage environment should be clean, dry and as
dust-free as possible and the ambient temperature should
be kept preferably within the +10°C to +40°C (+50°F to
+40°F) working range of the instrument.
