Always de-energise an uninsulated hazardous live conductor
under test before positioning the flexible current sensor around it.
Pull and unclip the flexible sensor from the sensor coupling at the
end marked with .
Referring to figure 1, and taking all necessary safety precautions,
wrap the flexible sensor around the conductor to be measured and
clip the flexible sensor end back into the sensor coupling.
Position the flexible sensor so the conductor under test is at the
centre of the sensor loop and perpendicular to the sensor loop.
Read the measured current from the display.
3.10 Position Sensitivity
If it is not possible to position the flexible sensor so the conductor
is at the centre of the loop, the measured value will have additional
errors dependant on the position of the conductor in the sensor loop.
See figure 2.

5. WARRANTY AND LIMITATION OF LIABILITY
This Martindale product is warranted to be free from defects in material
and workmanship under normal use and service. The warranty period is
2 years and begins on the date of receipt by the end user. This warranty
extends only to the original buyer or end-user customer, and does
not apply to fuses, disposable batteries, test leads or to any product
which, in Martindale’s opinion, has been misused, altered, neglected,
contaminated, or damaged by accident or abnormal conditions of
operation, handling or storage.
Martindale authorised re-sellers shall extend this warranty on new and
unused products to end-user customers only but have no authority to
extend a greater or different warranty on behalf of Martindale.
Martindale’s warranty obligation is limited, at Martindale’s option, to refund
of the purchase price, free of charge repair, or replacement of a defective
product which is returned to Martindale within the warranty period.
This warranty is the buyer’s sole and exclusive remedy and is in lieu of
all other warranties, expressed or implied, including but not limited to any
implied warranty of merchantability or fitness for a particular purpose.
Martindale shall not be liable for any special, indirect, incidental or
consequential damages or losses, including loss of data, arising from any
cause or theory.
Since some jurisdictions do not allow limitation of the term of an implied
warranty, or exclusion or limitation of incidental or consequential
damages, the limitations and exclusions of this warranty may not apply
to every buyer. If any part of any provision of this warranty is held invalid
or unenforceable by a court or other decision-maker of competent
jurisdiction, such holding will not affect the validity or enforceability of any
other provision or other part of that provision.
Nothing in this statement reduces your statutory rights.
