Maintenance
Battery Care The battery should be replaced annually, whenever you plan an extended period
of unattended monitoring, or whenever “BAT” appears in the display for more than an instant.
See Specifications for replacement type. If unit fails to operate after replacing the battery,
remove battery, press and release the ON/ZERO button then re-connect the battery. Remove
the battery before long-term storage.
Cleaning To obtain accurate, drift-free readings the sensor plate and especially the area around
the aperture must be kept absolutely clean at all times. Always keep the instrument in its
protective case when not actually taking measurements. Never touch the aperture with
anything-not even cotton swabs. To remove dust or other particulate matter, use low-
pressure instrument grade air. To remove severe contamination spray or flush with the smallest
practical amounts of clean technical grade isopropyl alcohol. The stand the instrument on the
aperture end and allow it to dry for several hours. DO NOT clean with any solvent on a regular
basis.
Zero Drift Apply anti-stat solution to plastic surrounding the sensor plate using lint free
applicator. DO NOT allow entry into aperture.
