This product complies with requirements of the following European
Community Directives: 89/ 336/ EEC (Electromagnetic Compatibility) and 73/ 23/
EEC (Low Voltage) as amended by 93/ 68/ EEC (CE Marking). However, electrical
noise or intense electromagnetic fields in the vicinity of the equipment may
disturb the measurement circuit. Measuring instruments will also respond to
unwanted signals that may be present within the measurement circuit. Users
should exercise care and take appropriate precautions to avoid misleading
results when making measurements in the presence of electronic interference.
MAINTENACE
If there appears to be a malfunction during the operation of the meter, the
following steps should be performed in order to isolate the cause of the
problem.
1. Check the battery. Replace the battery immediately when the “N”
symbol appears on the LCD.
2. Review the operating instructions for possible mistakes in operating procedure.
Except for the replacement of the battery, repair of the meter should be
performed only by a Factory Authorized Service Center or by other qualified
instrument service personnel. The front panel and case can be cleaned with
a mild solution of detergent and water. Apply sparingly with a soft cloth and
allow to dry completely before using. Do not use aromatic hydrocarbons or
chlorinated solvents for cleaning. If the meter is not to be used for periods of
longer than 60 days, remove the batteries and store them separately
Do not attempt to repair this Meter. It contains no user-serviceable parts.
Repair or servicing should only be performed by qualified personnel.

TROUBLE SHOOTING
If the instrument fails to operate, check batteries and test leads etc., and
replace as necessary. Double check operating procedure as described in this
user’s manual.
If the instrument voltage-resistance input terminal has subjected to high
voltage transient (caused by lightning or switching surge to the system) by
accident or abnormal conditions of operation, the series fusible resistors will
be blown off (become high impedance) like fuses to protect the user and the
instrument. 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.
Battery Replacement
Refer to the following figure to replace the batteries:
