4. MEASURING PROCEDURE

4-1 Humidity Measurement :

1. Press key to power on the meter.

2. The display will show the humidity reading value (%RH)

directly on the main display.

3. When the humidity value of the tested environment

changes, please wait for few minutes to get the stable

“%RH” reading.

4-2 Temperature Measurement :

1. Press key to power on the meter.

2. Press “°

F” key for select “°

C” or “°

F” unit.

3. The display will show the Temperature reading (°C or °F)

directly on the secondary display.

4-3 Dew Point Temperature Measurement :

1. Press key to power on the meter.

2. Press “MODE” key to display dew point temperature

reading on the main display. Press “MODE” key twice to

exit dew point temperature reading.

4-4 Wet Bulb Temperature Measurement :

1. Press key to power on the meter.

2. Press “MODE” key twice to display wet bulb temperature

reading on the main display. Press “MODE” key again to

exit wet bulb temperature reading.

1. Clear the manual memorized data

Press key for 3 seconds to turn off the meter.

Press and hold down “MEM” key, then press key to

turn on the meter, the “CLr” and “no” symbols are

displayed.

Press or key to select “YES” symbol is displayed.

Press ↵key to clear the manual memorized data.

2. Manual data memory

Press “MEM” once to store one set of readings to the

memory. At this moment, LCD will show the “M” symbol

and the memory address number is shown in the

secondary display. Total memory size is 99 sets.

When memory is full, LCD will show “FULL” symbol.

3. Manual memory data READ

Press “READ” key to enter READ mode, the LCD will

show “R” symbol and the memory address number is

shown in the secondary display

Press “READ” key to select the desired memory address

number data for display.

Press “MODE” key repeatedly to select the reading of

“Dew point” temperature, “Wet bulb” temperature and

humidity or temperature on the main display.

Press “TIME” key to display the time of the recorded data.

The real time will be displayed if the Real-time setting

function had been performed at power on when the reading

was stored, otherwise the elapsed time will be displayed.
