the same type of fuse or equivalent.
6.1 Battery and Fuse Replacement
conditions of operation, the series fusible resistors will be blown off

Most measuring functions through this terminal will then be open
circuit. The series fusible resistors and the spark gaps should then be
replaced by qualified technician. Refer to the LIMITED WARRANTY
section for obtaining warranty or repairing service.
9. LIMITED WARRANTY
With the exception of the batteries and the fuse, this instrument is
warranted against defects of material or workmanship which develop
within a period of one (1) year after the date of purchase by the
original owner. Proof of date of purchase will be required when
applying for repair or replacement under this guarantee. For this
reason, we strongly suggest that you keep your sales receipt safely
in your intrument storage case.
In the event a flaw develops in any of the units, please return it to
your dealer who will arrange repair or replacement. The manufacturer
will either repair or replace the tool ( at the manufacturer’s option)
free of charge providing the instrument is still under warranty. If the
warranty has expired, there will be a repair charge payable to your
dealer when you pick up the unit. When a unit has been repaired
or replaced under warranty, the replacement unit will extend the
warranty period of the original unit for six (6) months after the date of
replacement or until the original warranty expires, whichever is the
longest period. This warranty shall not apply to any problem, failure
or damage caused by improper use or inadequate maintenance
or care.
The manufacturer shall not be obligated to provide service under
this warranty or to repair damage resulting from attempts by
unauthorized persons to repair or service the units, other than to
replace the batteries, or to repair damage resulting from improper
use. Specifically if there is evidence of an attempt to open the units
the warranty is void.
Any implied warranties arising out of the sale of the units including
but not limited to implied warranties of merchantability and fitness for
a particular purpose are limited in duration to the above mentioned
one (1) year period, and the manufacturer shall not be liable for loss
of use of the instrument or other incidental damages, expenses or
economic loss. Some jurisdictions do not allow limitations on how
long implied warranties last or the exclusion or limitation of incidental
or consequential damages, so the above may not apply to you.
