Plug the sensor probe into 33% salt
bottle. Hold down and under normal mode to enter 33% calibration (Fig.15).
“CAL” and calibrating value (32.7% if at 25 C) are blinking on the LCD with current temperature
at the left.
Instrument
is now calibrating, and will finish in about 60 minutes when “CAL” and humidity
stop blinking. (Fig.16)
After 33% calibration, plug the sensor probe into 75% salt bottle, then press to enter 75%
calibration (Fig.17).
“CAL” and calibrating value (75.2% if at 25
°C) are blinking on the LCD with current temperature
at the left. Instrument is now calibrating. Wait about 60 minutes until blinking stops, then
calibration is completed and it returns to normal mode.
NOTE:
Users can also calibrate either point. To calibrate 33% only, press and exit when 33%
calibration is completed.
To calibrate 75% only, press or within the 5 minutes while initializing 33%
calibration.
