1. FEATURES
* Introduction :
WBGT ( wet-bulb globe temperature ) was developed
as a monitoring basis at US military training camps
and became widespread for the use in workplaces and
sports situation It is suggested in the international
standard ISO 7243, OSHA ( US Occupation Safety ),
Japan Society for Occupational Health and the SMA (
Sports Medicine Australia ) in establishing the
permissible heat exposure limits in health , sports or
other physical activities.
* Measurement : WBGT value ( Indoor/Outdoor Wet bulb
globe temperature ), Black globe temperature, Humidity,
Air temperature, Wet bulb temperature, Dew point Temp..
* Adjustable WBGT alarm setting, if the WBGT value over
the alarm threshold, the buzzer will sound along with
the flashing Display.
* Using to control and monitor of physical activity in hot
environment to limit the danger of heat related
injuries.
* Globe temperature measurement use the Pt sensor,
high accuracy.
* Fast humidity measuring response time.
* Direct measurement of the radiation effect with
a brass black ball in 75 mm dia.
* Sensor protecting mechanism.
* Real time SD memory card Datalogger, it Built-in Clock
and Calendar, real time data recorder , sampling time set
from 1 second to 3600 seconds.
* Manual datalogger is available ( set the sampling
time to 0 ), during execute the manual datalogger
function, it can set the different position ( location ) No.
( position 1 to position 99 ).

8. POWER SUPPLY from DC
ADAPTER
The meter also can supply the power supply from the
DC 9V Power Adapter ( optional ). Insert the plug of
Power Adapter into " DC 9V Power Adapter Input Socket
" ( 3-12, Fig. 1 ). The meter will permanent power ON
when use the DC ADAPTER power supply ( The power
Button function is disable ).
9. BATTERY REPLACEMENT
1)When the left corner of LCD display show " ", it
is necessary to replace the battery. However, in-spec.
measurement may still be made for several hours after
low battery indicator appears before the instrument
become inaccurate.
2)Loose the screws of the " Battery Cover Screws " ( 3-14,
Fig. 1 ) and take away the " Battery Cover " ( 3-13, Fig. 1 )
from the instrument and remove the battery.
3)Replace with DC 1.5 V battery ( UM3, AA,
Alkaline/heavy duty ) x 6 PCs, and reinstate the cover.
4)Make sure the battery cover is secured after changing
the battery.

10. SYSTEM RESET
If the meter happen the troubles such as :
CPU system is hold ( for example, the key button can
not be operated... ).
Then make the system RESET will fix the problem.
The system RESET procedures will be either following
method :
During the power on, use a pin to press the " Reset
Button " ( 3-11, Fig. 1 ) once a while will reset the
circuit system.
11. RS232 PC SERIAL INTERFACE
The instrument has RS232 PC serial interface via a 3.5
mm terminal ( 3-10, Fig. 1 ).
The data output is a 16 digit stream which can be
utilized for user's specific application.
A RS232 lead with the following connection will be
required to link the instrument with the PC serial port.
23
Meter PC
(9W 'D" Connector)
Center Pin..........................Pin 4
(3.5 mm jack plug)
Ground/shield.......................Pin 2
2.2 K

Pin 5
The 16 digits data stream will be displayed in the
following format :
D15 D14 D13 D12 D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0
Each digit indicates the following status :
D15 Start Word
D14 4
D13 When send the WBGT display data = 1
When send the Humidity display data = 2
When send the TA display data = 3
When send the TG display data = 4
When send the WB display data = 5
When send the Dew point display data = 6
D12, D11 Annunciator for Display
= 01 ℃ = 02℉ % RH = 04
D10 Polarity
0 = Positive 1 = Negative
D9 Decimal Point(DP), position from right to the
left
0 = No DP, 1= 1 DP, 2 = 2 DP, 3 = 3 DP
D8 to D1 Display reading, D1 = LSD, D8 = MSD
For example :
If the display reading is 1234, then D8 to
D1 is : 00001234
D0 End Word
