Secondary Test
Before beginning this test, re-check the meter’s battery and re-zero the
meter. Also, perform the probe test. Steps to perform the probe test
are outlined in the Pre-Installation Task section of this manual.
• Remove the beaker from the range. Empty the water and refill with
cold water to 275 cc level and place in center of oven shelf. Close and
latch the oven door.
• Set the timer for five minutes on “High” power.
• Start the scan when the power indicator lamp comes on, as before.
Select “Fast” response and quickly scan the entire gasket perimeter to
confirm location of maximum radiation indicated on initial test.
• Once the origin of the maximum leakage point has been confirmed,
turn the select switch to “Slow” response and monitor for two minutes,
recording the maximum repeatable values obtained during this survey.
This maximum reading is to be used in judging compliance with the
following limit:
• All ovens manufactured after September 1971, maximum allowable
5 mw/cm 2 .
If the maximum reading exceeds the acceptable limit, the range must
be repaired.
After repairs are made, complete testing must be repeated.
