TRIPLETT HS10 Heat Stress Meter Wet Bulb Global Temperature and Heat Index Monitor
Introduction
Congratulations on your purchase of the Triplett HS10 Heat Stress Wet Bulb Global Temperature (WBGT) and Heat Index (HI) Monitor
This compact checker measures air temperature, globe temperature, and humidity to give heat stress index for using in control of physical activity in hot environment to limit the danger of heat-related injuries.
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 situations.
It is suggested in an international standard ISO 7243 and many governments
such as OSHA (US Occupational Safety & Health Administration), SMA(Sports
Medicine Australia)and Japan Society for Occupational Health in establishing
the permissible heat exposure limits in occupational health, sports or other
physical activities.
The applications of the heat index can be in construction, iron and steel
foundries, bricks-firing plants, glass facilities, boiler rooms, mining sites,
army training, marathon, beach activities and so on.
The heat index was developed by the US National Weather Service to help people avoid heat illness. Prolonged exposure and/or physical activity at a high heat index is likely to lead to sun stroke, heat cramps, heat exhaustion and even death. However, please be aware that heat index is not an exact science. The values reached are approximations. Ultimately, the final decision of whether or not to exercise or work belongs to the individual, athletic trainer or employer.

POWER
Press to turn ON (press1 second) and turn OFF (press 2 seconds) the meter. All indicators are shown on the LCD when powered ON and the meter enters measurement mode. The firmware revision is displayed on the LCD for 1 second when powered ON.
MEASUREMENT
When in measurement mode, the WBGT value, temperature and humidity values are displayed on the LCD.
SOUND LEVEL
The user can press the [▲] or [▼] key to adjust the volume of the alarm. In
measuring mode, press [▲] or [▼] key to adjust the volume in 0dB > 60dB >75dB
respectively. The buzzer icon will be displayed.
Note: No Buzzer icon is displayed on the LCD when the sound is 0dB.
DANGER ZONE INDICATOR
For both WBGT and HI there are 4 levels of heat stress danger zone indications
at the top of the LCD.
ALARM
When the measured heat stress value is over alarm threshold, the red LED, buzzer and measured value will all blink every second as a reminder. After 30 seconds, it beeps 1 time per minute. The user can disable beep sound at any time when pressing [▼] key. The alarm threshold value can be reprogrammed. Check “SETUP” Mode in the following section in this manual for further instruction.

This function allow users to customize their own default settings. Press the button + [▲]+ [▼] buttons simultaneously for 3 seconds to enter SETUP Mode. The meter will return to normal display while keys are inactive for 30 sec in setup mode. Display for either WBGT & HI (Heat Index) is switchable by the user.
IN/OUT SWITCH (ONLY for WBGT mode)
This function serves to calculate WBGT without [IN] or with [OUT] direct sun exposure. Under IN/OUT modes, press [▲] or [▼] to switch [IN / OUT] then press to confirm
ALARM THRESHOLD SETTING
This function allows users to customize alarm threshold or stay at factory default alarm threshold. While choosing to stay at factory default alarm threshold, please select [OFF]. [OFF] means to turn off customization function.

Note: If user prefers to monitor the heat stress in a complete silent mode the following procedure can disable the alarm function so LED, buzzer and alarm related icons are all OFF. While adjusting alarm threshold value, pressing [▲] and [▼] key simultaneously. The alarm threshold will show [–.-] on the LCD Press [▲] and [▼] again to revert the status.
