5-1 Important Preliminary checks

DANGER

Ɣ Do not make measurements on a circuit in which the electrical potential exceeds

AC600V.

Ɣ Connect the Power cord to a socket outlet. Never connect it to the socket outlet of
AC240V or more

.

Ɣ The Clamp sensor, Voltage test leads and Power cord are to be connected to the
instrument first.
Ɣ The Voltage test leads or Clamp sensors should not be connected to the input
terminals of the instrument if not required for measurement.
Ɣ The instrument should always be connected on the downstream side of a circuit

breaker, which is safer than the upstream side.

Ɣ Do not open-circuit the secondary side of a supplementary CT while it is energized

because of the high voltage generated at the secondary side terminals.

Ɣ Be careful to avoid short-circuiting the power line with the un-insulated part of the
voltage test probes during the setting up of the instrument.

Transformer jaw tips are

designed in such a way to avoid short-circuiting. If the circuit under test has exposed
conductive parts, extra care should be taken to minimize the possibility of shorting.

WARNING

Ɣ To avoid possible electric shock and short-circuit, always turn off the line under test
when setting up the instrument.
Ɣ Do not touch the un-insulated tip of Voltage test probes. The use of safety insulted
gloves is recommended.


Ɣ Clamp sensor direction for correct measurement:

Ensure that the arrow mark on the clamp sensor points towards to
load side.
