Filter 3 is a four stage, eight pole filter designed for faster
scanning of ovens having slow mode stirrer speeds in a
manner similar to that used by Automatic Microwave
Oven Scanning Systems (AMOSS). Special test
procedures are required to use this filter for compliance
testing.
Filter 4 is a four stage, eight pole filter designed for faster
scanning of ovens having faster mode stirrer speeds in a

Oven Scanning Systems (AMOSS). Special test
procedures are required to use this filter for compliance
testing.
Note: Use of Filters 3 and 4 would require the
development and submission of a revised compliance plan
with CDRH. Such a plan would need to show an error
analysis of sample data comparing the proposed scan rate
with current CDRH testing guidelines. Contact Holaday
Industries for further information.
Peak Hold
The Peak Hold function captures and holds the highest
leakage reading displayed by the instrument. Peak Hold
is activated by pushing the Peak Hold switch on the front
panel. An LED indicator lights to show that the
instrument is in the Peak Hold mode. The peak reading
is stored as a digital value and displayed until the Zero
switch is pushed to reset the instrument or until the
probe is inserted into the optional Zero Chamber. The
peak reading displayed is the value obtained following all
filtering and signal conditioning.
While in Peak Hold, the analog Bar Graph display shows
the current instantaneous RF reading, without filtering
(refer to figure 2). A Bar Graph segment remains lit to
