Safety Inspection

If there is any indication that safe
operation of the equipment is no
longer warranted:
Disconnect the power supply by
unplugging the power cord from the
wall outlet (mains)
> Lock the equipment in a secure
place to ensure that it cannot be
used for the time being
Safe operation of the equipment is
no longer ensured when:
– there is visible damage to the
device or power cord,
– the analyzer no longer functions
properly,
– the equipment has been stored
for a relatively long period under
unfavorable conditions, or
– the equipment has been subjected
to rough handling during shipment.
In this case, notify your nearest
Denver Service Center. Maintenance
and repair work may be performed
only by service technicians who are
authorized by Denver and who:
– have access to the required service
and maintenance manuals, and
– have attended the relevant service
training courses.

We recommend having the moisture
analyzer inspected regularly accord-
ing to the following checklist by a
qualified Denver service technician:
– Resistance of the protective
grounding conductor < 0.2 ohm
measured with a commercially
available multimeter
– Insulation resistance > 2
megaohms measured with a con-
stant voltage of at least 500 volts
at a 500 kohm load
A qualified Denver service technician
should determine which tests are
performed at what intervals, based
on ambient and operating
conditions. Inspections must be
performed at least once a year.
