This instruction manual is V ol. 2 [Function instruc tions].

For clock adjustment, measurement unit se lection, etc., re fer to Vol. 1 [Basic instruction s].

 [Auto-power-off function]

For avoiding the comsumption of the ba tteries, the auto-power-off function of
this “temperature/humiditymeter” has been set at ON (active) as a factory
default setting. If no key is pressed for 1 minute, the continuous measurement
will automatically stop and the mode will move to the clock mode.

For setting of the auto-power-off function to OFF:
Press DISP key to go to the continuous measurement mode ( Ref. [1.1Continuous

measureme nt] and then press DISP key again f or about 2 second s to go to
the programm ing mode. In th e programming m ode, press DISP k ey several
times to go to the auto-power-off selection mode with “Auto” lit in the sub

display. In the auto-power-off selection mode, “on” (active) will flash in the

Reference

This paragraph describes “Measurement and data logging” of the RH32 series temperature/humidity meter .
For the exact operation, program parameters first in [4 . Parameter programm ing].

1.1 Continuous measurement

By pressing DISP key in the clock mo de, the temperature/humidit y measureme nt will s tart after bars are di splayed for about 1 second . The
measured temperature will be displayed in the main display 1 and the measu red hum id ity wil l be displaye d in the main disp lay 2 together with
the display of month, day , hour and minute at the measurement.
The temperature measurement unit and the humidity measurement unit being displayed are the units already selected.
For the selection of the measurement unit, refer to [5.3 Selection of measurement unit] in the separated instruction manual Vol. 1
<Basic instructions>.
If “ALARM“ lights in the main marker, the measurement value has exceeded a high alarm set point or a low alarm set point. Check the
set points and reprogram them if necessary. Refer to [4.2 High alarm set point] and [4.3 Low alarm set point].

Remarks

When the clock is di splayed afte r the measu rement for a bout 1 minute , the auto-p ower -off fu nction is “on“ (active).
For continuing the continuous measurement, select the auto-power-off function to “oFF“ (release).

(Ref. [4.6 Auto-power-off ].

Caution

When the measured temperature is lower than the mi nimum limit, “uFL“ will be displayed and, when it is higher
than the maximum limit, “oFL“ will be displayed.

1.2 Storing (data logging) mode

This meter has a memory storing each maximum 8000 da ta of measured temperature and humidity.
The measured data are stored into an EEPROM and can’t be erased even if the batteries are dead.
T wo storing (data logging) modes of manual storage mode and automatic storage mode are available.

Storage mode Content Number of data
Manual storage mode In the continuous measurement, the measured data is stored by

pressing ENT key.

1.3 Manual storage mode

The temperature measured value and the humidity measured value in the continuous measurement mode are stored by pressing ENT key with

the time data of year , month, day, hour, and minute at th e measurement.

1) Go to the continuous measurement mode. (R ef. [1.1 Contin uous measuremen t])

2) Press ENT key for about 2 seconds. “LOG“ will instantly light in the main marker, and the temperature measured value and the humidity
measured value are stored with the time data of year, month, day, hour , and minute. Release ENT key once.

3) Repeat the procedure 2) for the next data storage.

Caution

The manual storage will be disabled during the automatic storage (with “LOG“ lit in the main marker,

<< Definition of totalized temperature>>

The totalized temperature is computed by the following formula.

1) H totalized temperature = (Measured temperature – totalizing reference temperature) x Hour
Note: Computed only at

Measured temperature – totalizing reference temperature > 0

2) L totalized temperature = (Totalizing reference temperature - measured temperature) x Hour
Note: Computed only at

T otalizing reference temperature - measured temperature > 0

Ex. 1) If the totalizing referen ce temperature is 0.0 ºC and the measured temperature was 25.0ºC for 100 hours, the H totalized temperature is:

（25.0 - 0）x100 = 2500ºCH

Ex. 2) If the totalizing reference temperature is 10.0ºC, and the measured temperature was 25.0ºC for 100 hours, 15.0ºC for 50 hours and 5.0ºC

for 100 hours, th e H total ized temperature is :
(25.0 - 10.0) x 100 +(15.0 - 10.0) x 50 = 1555ºCH

Ex. 3) If the totalizing reference temperature is 10.0ºC, and th e measured temperature was 25.0ºC for 100 hours, 15.0ºC for 50 hours and 5.0ºC

for 100 hours, the L totalized temperature is:
(10.0 - 5.0) x 50 = 250ºCH

Remarks

The totalizing direction (H or L) and the totalizing reference temperature are programmed in [4.5Totalizing
