SMART 6 Maintenance
cm2).The instrument is equipped with a safety interlock system which stops the generation of microwave energy
when the instrument cover is not securely closed. If the interlock system fails, a monitoring mechanism will blow
the fuse through which power is supplied to the magnetron, rendering the microwave power system inoperable.
• To verify that the cover is sealing and the interlock system is working properly, the SMART 6 should be routinely
tested for microwave leakage. To test for leakage, operate the instrument at 100% power for five (5) minutes.
While it is operating, use a federally approved microwave leakage detector such as the Holaday Model HI-1500
and measure the microwave leakage around the cavity and at the fan grill. Leakage should not exceed 5 mW/
cm2. If the instrument shows excessive microwave leakage, do not attempt further operation. Contact the CEM
Service Department or the nearest CEM subsidiary or distributor.
• Microwave test meters are available from CEM Corporation. CEM does not recommend use of inexpensive
meters available in electronics stores because they lack the necessary sensitivity to properly test an instrument
for microwave leakage.
• IntelliTemp Calibration
• Sample temperature is controlled by CEM’s trademark IntelliTemp process. In order for IntelliTemp to function
properly and ensure the most accurate results possible, the IR sensor should be calibrated and validated.
IntelliTemp calibration can be performed during a preventive maintenance visit by a certified CEM Service
Technician, or the calibration device can be purchased from CEM.
• When performing the calibration, follow the instructions included with the calibration device to ensure that the
SMART 6 is reading the temperature accurately.
• IntelliTemp calibration is included in the annual service contract.
WARNING
Failure to perform the necessary maintenance to keep the SMART 6 clean and operational can lead to a
reduction in precision, inaccurate results, or damage the system, creating an unsafe testing environment
due to fire or volatiles in the cavity.
