32 Wire & Cable ASIA – March/April 2013
Improved testing of power distribution equipment during the
installation of cables is provided by the Cropico DO4000 range
of high performance, digital milliohm meters now available from
Seaward.
The portable and
rugged instrument
features a number of
advanced features to
test and measure
accurately the integrity
of switchgear cable
joints and other
distribution equipment
to ensure they are fully
maintained and func-
tion correctly.
These include forward
and reverse current
measurement with
auto averaging, true
current zero, long
scale length and a
selectable measure-
ment range from
40mW to 4kW with
respective resolutions
between 10mW and
1W.
Within the range,
model 4001 also
includes temperature
compensation, with
preset coefficients for
copper and aluminium
plus user settable coefficients for other materials. Temperature
measurement over the range –50 to +800ºC is also available.
Protection up to 415V rms is provided at the measurement
terminals and push button operation is achieved easily by
clearly marked function controls. Direct reading measured
values are displayed on a four-digit LCD display.
Over range and low battery indication is also provided and
warning LEDs illuminate when an open circuit lead condition is
detected.
The 4000 series can be supplied with long leads to allow for
accurate measurement of large blades, and a rechargeable
battery option includes a battery pack, docking station and
charger.
