Shipping Information
To prepare the Current Shunt Set for shipping, place them in the appropriate pre-cut foam
insert positions in the transit/storage case and secure the lid.
When shipping individual Current Shunts, completely enclose them within at least 5 cm
(2 inches) of polyurethane foam cushioning and pack them in a crush-proof container.
Storage Information
To prepare the Current Shunts for storage, place them in their transit/storage case, and
secure the lid. Then, store the container in a location that complies with the
environmental specifications described earlier in the General Specifications . Storage
outside these conditions may reduce the battery life of the 1 mA shunt or cause a
temporary change in the resistance of the Current Shunts by up to ±20 ppm. When
returned to an acceptable operating environment, the Current Shunts will recover to their
original resistance value within 30 days.
Acceptance Test
Upon initial receipt of the Current Shunts, perform the following acceptance test to
ensure that they are functional:
1.
Inspect the physical condition of the Current Shunts for obvious physical damage,
including connector damage as described under General Maintenance/Cleaning .
Repair any damage before proceeding.
Instructions for contacting Fluke are provided earlier in this manual.
2. Functionally test each Current Shunt by applying the nominal current to its input. At
nominal current, the output voltage for each Current Shunt should be approximately
0.8 volts.
Note
Each Current Shunt produces 0.8 volts output for an input at nominal
operating current. The highest current shunts (10 A and above) get warm
when operating at full current. The 50 A and 100 A shunts may become
uncomfortable to touch; their operating temperature can be as high as
70 ºC (158 ºF).
