- Wait at least 10 - 15 minutes for the sensor to stabilize; use a
multimeter or the transmitter display to monitor the stabilization.
- Press the buttons ▲ and ▼ to adjust the display or multimeter
reading (when using a multimeter calculate the current value
corresponding to the reference humidity by using the equations
presented in page 47) and conclude the calibration with the button
E.
- Restore the dip switch settings. Set the calibration dip switch to
position DISABLED (down).
Temperature calibration in one point
Always use a high quality standard for calibrating the temperature.
NOTE
If you use serial commands, please refer to page 40.
- Set the calibration dip switch to position ENABLED (up).
- Set the calibration dip switches to position 'TEMPERATURE
CALIBRATION
' according to the table printed on the protective
cover. The temperature value measured by the transmitter appears
on the display as well as the text SET LO on the lower left corner. If
the transmitter has no display, the LED indicator starts to blink.
- Let the sensor stabilize; use a multimeter or the transmitter display
to monitor the stabilization.
- Press the buttons ▲ and ▼ to adjust the display or multimeter
reading to correspond the reference value (when using a multimeter
calculate the current value corresponding to the reference humidity
by using the equations presented in page 46). Conclude the one
point calibration by pressing the button E twice.
