6. Care and maintenance
The Protimeter HygroMaster-L is a precision-built electronic
instrument that will provide many years of reliable service if
the following points are observed:
► When not in use, keep the HygroMaster-L instrument and
its accessories in the pouch. Store the pouch in a stable,
dust-free environment and keep it out of direct sunlight
► If the instrument is to be stored for more than four weeks
or if the low battery power symbol appears on the display,
remove the battery from the instrument.
► Check the condition of the HygroMaster-L accessories on
a regular basis and replace them if they become worn or
damaged.
► To preserve the calibration characteristics, Hygrostick
probes shouldn't be exposed to saturated environments. If
this is unavoidable Hygrostick probes should be replaced
on a regular basis and their calibration should be checked
frequently.
