4. Operation Instructions
The H300 could take as long as ten minutes for the display to completely “settle” and display
the actual temperature or relative humidity level if the meter is exposed to two vastly different
environments. The sensors used to make the environmental measurements must have time to
acclimate to the test environment.

4-2 Measuring Procedure
The H300 default unit of measure is °C. To switch to °F see section 5-1. The sampling time
default for data logging is set at2 seconds. To change this sampling time see section 4-7.
4-3 Humidity & Temperature Measurement
1. Plug the “Probe Plug” (4-11, Fig. 1) into the “Probe Input Socket” (4-10, Fig. 1).
2. Power on the meter by pressing the “Power Button” (4-2, Fig.1) for 2 seconds. The LCD will
show the units of measure on the display after a quick self test. It will displaythe %RH in the
main display and temperature in the bottom section of the LCD.
3. The meter displays temperature in °C by default, t o switch to °F see section 5-1.
4-4 DEW Point Measurement
To measure DEW Point follow the instructions shown in section 4-3 and then press the
“Function Button” (4-5, Fig. 1) momentarily once. The LCD will show the word DEW in the main
display and temperature below.
4-5 Data Hold
While taking measurements you can freeze the displayed value by pressing the “Hold Button”
(4-3, Fig. 1) once. The HOLD symbol will be displayed along with the held measured value on
the LCD. By pressing the “Hold Button” (4-3, Fig. 1) a second time will release the displayed
value and turn off the data hold function.
4-6 Data Record (MAX/MIN)
1. To record the maximum and minimum readings, press the “REC Button”(4-4, Fig. 1). The
REC symbol will be displayed on the LCD. By pressing the “REC Button” (4-4, Fig. 1) you can
toggle through the Max and Min values.
2. To delete the recorded values press and hold the “Hold Button” (4-3, Fig. 1) for about 3
seconds.
3. To stop using the REC function, press and hold the “REC Button” (4-4, Fig. 1) for at least 3
seconds.

(see section 5-1 if you wish to change the unit of measure).
3. Press the “Logger Button” (4-6, Fig.1) and SEC will be displayed on the bottom of the LCD.
4. To cycle through the number of seconds you would like meter to wait between loggings,
press the “Function Button” (4-5, Fig. 1). By pressing the “Function Button” (4-5, Fig. 1) the
following number of seconds will be displayed on the top of the LCD: 1, 2, 10, 30, 60, 600,
1800 or 3600.
5. Once the number seconds you require is displayed on the LCD, press the “Logger Button”
(4-6, Fig.1).
6. Press the “Enter Button” (4-4, Fig. 1) to exit the settings menu, then press the “ESC Button”
(4-3, Fig. 1).

7. Press the “REC Button” (4-4, Fig.1) momentarily to start the data log function. The REC
symbol will be displayed on the LCD. The data logger function can save up to 1000 values of
measure (either Humidity & Temp. or Dew Point & Temp).
8. Press the “Logger Button” (4-6, Fig.1) and the meter will start logging. You will see the A
flashing on the top of the LCDevery time a logging event has occurred. The A flashing will
match the number of seconds you set in the setup of the data logger function.

2. Press the “Logger Button” (4-6, Fig.1) every time you would like the meter to record a value.
You will see an A flash in the top of the LCD. The meter will not record another measurement
until you press the “Logger Button” (4-6, Fig.1) again.
3. If the A in the top of the LCD and the lower display are flashing then, it indicates that the
