Problem Possible Causes and Solutions
AC voltage present on
the chassis
Use a wall plug tester to check the main power plug at the wall. Use an ohmmeter to
check the continuity between the ground prong on the PEM and the chassis. If the
resistance reading is greater than three ohms, there is a problem. Check the power cord
for continuity on the ground prongs. If the resistance is greater than one ohm, re place the
power cord.
Power Up The instrument is equipped with operator accessible fuses. If a fuse blows, it may be due
to a power surge or failure of a component. Replace the fuse once. If the fuse blows a
second time, it is likely caused by failure of a component part. If this occurs, contact an
Authorized Service Center. Always replace the fuse with one of the same rating, voltage,
and type. Never replace the fuse with one of a higher current rating.
CE Comments14.2
EMC Directive14.2.1
Hart Scientifics’ equipment has been tested to meet the European Electromagnetic
Compatibility Directive (EMC Directive, 89/336/EEC). The Declaration of
Conformity for your instrument lists the specific standards to which the unit was
tested.
For units used in the “field”, a slight degradation of accuracy may be noticed between
300-350 MHz with a field intensity of 10V/M at the unit. A piece of equipment in
proximity to the unit under test must emit greater than 1000 times the permissible CE
standard (EN55022) at these specific frequencies to have any effect on the unit. Units
used in a laboratory are not affected.
Low Voltage Directive (Safety)14.2.2
In order to comply with the European Low Voltage Directive (73/23/EEC), Hart
Scientific equipment has been designed to meet the EN 61010-1 and EN 61010-2-010
standards.
