Introduction
The Model i400 (hereafter called “the Current Clamp”) is an ac
current clamp that outputs 1 mA/A via safety-shrouded banana
plugs; it is designed to extend the measuring capability of an
ac current meter to 400 A.

To ensure safe operation and service of the Current
Clamp, follow these instructions:
•
•
•
•
•
•
•
•
Application around and removal from hazardous live
conductors is permitted.
Product is protected by double insulation.
Risk of Danger. Important information. See Instruction Sheet.
Hazardous voltage.
Conforms to relevant Canadian Standards Association
directives.
Conforms to relevant European Union directives.
Read the operating instructions before use and
follow all safety instructions.
Use the Current Clamp only as specified in the
operating instructions, otherwise the clamp’s safety
features may not protect you.
Adhere to local and national safety codes.
Individual protective equipment must be used to
prevent shock and arc blast injury where hazardous
live conductors are exposed.
Do not hold the Current Clamp anywhere beyond
the tactile barrier, see Figure 1.
Before each use, inspect the Current Clamp. Look
for cracks or missing portions of the clamp housing
or output cable insulation. Also look for loose or
weakened components. Pay particular attention to
the insulation surrounding the jaws.
Never use the clamp on a circuit with voltages
higher than 1000 V CAT III or 600 V CAT IV.
•
•
Use extreme caution when working around bare
conductors or bus bars. Contact with the conductor
could result in electric shock.
Use caution when working with voltages above 60 V
dc or 30 V ac. Such voltages pose a shock hazard.
Instruction Sheet
CAT III equipment is designed to protect
against transients in equipment in fixed-
equipment installations, such as distribution
panels, feeders and short branch circuits, and
lighting systems in large buildings.
CAT IV equipment is designed to protect
against transients from the primary supply
level, such as an electricity meter or an
overhead or underground utility service.

Low-Level Current Measurements
The Current Clamp is specified to measure currents of 1 A or
greater. Measurement accuracy of currents less than 1 A is
unspecified.
Operation
To use the i400, (refer to Figure 1):
20 mA ac or greater current range
Banana inputs
Input accuracy of 2 % or better to take full advantage of
the accuracy of the Current Clamp.
Input impedance of < 10 Ω
Center the conductor inside the Current Clamp jaw.
Make sure the clamp is perpendicular to the conductor.
For optimal reading, make sure the conductor is positioned
between the alignment marks on the jaw of the Current
Clamp.
Avoid taking measurements close to other current-carrying
conductors.
The Current Clamp displays current readings at 1/1000 of
the actual current on the conductor. For example, a
5 A input current will be transformed into a 5 mA output
current.
