Wagner Meters Rapid RH 4.0 EX, Руководство пользователя

Страница: 7 / 14

When ready to take readings, remove the orange protective
cap from the Smart Sensor, and ensure no dust or debris are
inside. Insert the Rapid RH
®
4.0 Easy Reader firmly until it
comes fully into contact with the bottom of the Smart Sensor.
Hold the
Easy Reader
in place until the first relative humidity
reading appears on the screen (about three seconds),
then immediately remove the Easy Reader . The display
will toggle back and forth between the relative humidity
value (when the cursor is next to the %RH symbol) and the
temperature value (when the cursor is next to the °F or °C
symbol*). Once the Easy Reader is removed from the Smart
Sensor, the readings from that Smart Sensor will continue to
display for approximately 5 minutes or until the Easy Reader
is reinserted into another Smart Sensor. After removal, wait
at least 5 seconds before inserting the Easy Reader into
another Smart Sensor. Replace the
Easy Reader’s
plastic
end caps when not in use.
In most cases, one hour after installation, the Smart Sensor
will generally give a reading within 3% RH of the reading
you would see after the ASTM-required 72-hour mark. Just
remember to follow the ASTM F2170 procedures pertaining
to equilibration time.
