OPERATING &
MAINTENANCE TIPS
When the icon appears at the upper
right of the display (Fig. 2, Callout A), it’s
time to replace the “9V” battery that powers
the instrument (although measurements will
remain valid for several hours after the icon
first appears). To replace the battery, follow
the instructions on pages 6 and 7.
To prevent dust and moisture from
degrading the performance of the humidity
and temperature sensors, after each
measurement session rotate the sensor
protection cap to close its three vents.
Do not operate the EP8703 in the presence
of a flammable or explosive gas or near an
arc welder or induction heater.
After subjecting the unit to a large change
in ambient temperature, wait at least 30
minutes before making measurements to
guarantee the accuracy of readings.
Remove the battery when storing the unit or
when you do not expect to use it for an
extended period of time (months rather than
weeks).
Do not drop or disassemble the EP8703 or
immerse it in water.
