4. MEASURING PROCEDURE
Terminal layout Fig. 2
4-1 Terminal connection
1)Input the ACV power ( 90 to 260 ACV ) to T1, T2.
Do not input the
over voltage to the
AC input terminals.
2)Connect the " Humidity Control Relay " output from T3, T4.
Connect the " Temp. Control Relay " output from T5, T6.
4-2 Humidity/Temp. measurement
1)Connect the " Probe plug " ( 3-16, Fig. 1 ) to
" Input socket " ( 3-14, Fig. 1 ).
2)Power on the meter, the " Display " ( 3-1, Fig. 1 ) will
show the humidity value, in the same time the " %RH
indicator " ( 3-10, Fig. 1 ) will light.

]
3)Press the " RH/Temp Button " ( 3-7, Fig. 1 ) once,
the " Temp. indicator " ( 3-11, Fig. 1 ) will light, the
" Display " ( 3-1, Fig. 1 ) will show the Temp. value.
* Press the " RH/Temp Button " ( 3-7, Fig. 1 ) once again,
the " Display " will return the " Humidity value ", in the
same time the " %RH indicator " ( 3-10, Fig. 1 ) will light again.
4-3 1st layer setting procedures
LoLt Low Limit
HILt High Limit
Low Limit Value Setting
1)Press the " Set Button " ( 3-4, Fig. 1 ) once, the "
Display " will show " LoLt ", now the meter is ready
for the Humidity " Low Limit " value setting.
Press the " RH/Temp Button " ( 3-7, Fig. 1 ) once,
the " Temp indicator " ( 3-11, Fig. 1 ) will light, now
the meter is ready for the Temperature " Low Limit "
value setting.
Remark :
* Under " Display " show " LoLt ", if " % RH indicator "
( 3-10, Fig. 1 ) is lit, meter is ready for " Humidity
Low Limit " setting.
* Under " Display " show " LoLt ", if " Temp. indicator "
( 3-11, Fig. 1 ) is lit, meter is ready for
" Temperature Low Limit " valuesetting.
* The function of " Low Limit value " setting, refer to
page 10, Fig. 2.

2)Use the " Button " ( 3-5, Fig. 1 ) and the "▼▲
Button " ( 3-6, Fig. 1 ) to adjust the desiring " Low
Limit " value.
* When adjust the value, the " SV indicator " ( 3-3, Fig. 1 )
will light.
High Limit Value Setting
1)After set the " Low Limit " value, press the " Set
Button " ( 3-4, Fig. 1 ) twice, the " Display " will show
" HILt ", now the meter is ready for the humidity
" High Limit " value setting.
Press the " RH/Temp Button " ( 3-7, Fig. 1 ) once,
the " Temp indicator " ( 3-11, Fig. 1 ) will light, now
the meter is ready for the Temperature " High Limit "
value setting.
Remark :
* Under " Display " show " HILt ", if " % RH indicator "
( 3-10, Fig. 1 ) is lit , meter is ready for " Humidity
High Limit value " setting.
* Under " Display " show " HILt ", if " Temp. indicator "
( 3-11, Fig. 1 ) is lit, it meter is ready for
" Temperature High Limit value " setting.
* The function of " High Limit value " setting, refer to
page 10, Fig. 2.
2)Use the " Button " ( 3-5, Fig. 1 ) and the "▼▲
Button " ( 3-6, Fig. 1 ) to adjust the desiring " High
Limit " value.
* When adjust the value, the " SV indicator " ( 3-3, Fig. 1 )
will light.
