INSTRUMENT OPERATION

The instrument is switched on by pressing the ON/OFF button. To obtain accurate humidity measurements, allow the instrument to stabilise in the environment for a minimum of one minute. To maximise accuracy, allow airflow across the sensor.

MAX/MIN

Press the MAX/MIN button to display the values. The instrument retains the max/min values when switched off. To reset, press the MAX/MIN button for three seconds, 'rst' will be displayed.

MODE

Press the MODE button to change the display between %rh, temperature and dew point measurements.

AUTO-OFF

The instrument will switch off automatically after 10 minutes. To disable auto-off press the HOLD button whilst switching on the instrument (this is reset when the instrument is switched off).

°C/°F

The unit can be switched between °C and °F by pressing the MODE button for three seconds.

ERROR MESSAGE

'Err' will appear in the display

If communication with the sensor has failed
If the sensor is contaminated or wet
If the instrument has developed a fault

SENSORS

Care must be taken not to contaminate the relative humidity (%rh) sensor otherwise its accuracy can be reduced. DO NOT submerge in water or any other substance.

BATTERY REPLACEMENT

The instrument will display 'LO BAT' to warn that the batteries will need changing soon. The instrument continues to measure accurately but after further usage the instrument will display 'flat bat' and shutdown. Replace the batteries with three AAA batteries located under the rear cover that is held in place by a single screw.

IPA and other solvents may cause damage to the case and screen of this instrument.
