HSDL300
Heat Stress/ WBGT Datalogger

Introduction

Thank you for purchasing the Triplett HSDL300 Heat Index WBGT Datalogger. The HSDL300 meter measures air temperature, globe temperature, and humidity to give heat stress 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. 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.

Features:

• Direct measurement of the radiation
• Effect with a brass black ball.
• Adjustable WBGT alarm threshold
• Audible beeper for heat stress monitoring
• Sensor protecting mechanism
• Backlight indicator function (Green, yellow, red, flashing red )
• PC connect for auto logging

Function Buttons

-Press power key to turn on/off the meter. When meter is powered on, APO displayed on LCD.
-Press + key to turn on the meter in non-APO mode. NO APO on LCD.
-You will see the firmware version on the LCD for 1 second while power on.

-In normal mode, press TA/TG key to switch the displayed temperature from TA to TG or TG to TA.

-In normal mode, press MAX/MIN key to switch the displayed parameter to max/min and then return to normal. The value is counted from power on. If you want to reset the value, power off the meter. (Note: Max/Min value will be show  on LCD for 60 seconds then return to normal mode automatically. -In setup mode, press this key to exit from setup and return to normal mode.

-In normal mode, long press SET key to enter setting mode.
-In setup mode, Key is used for setting / save.
-In logging standby status, press this key to start or stop.
-In normal mode, press IN/ OUT key to switch the WBGT mode as Indoor or Outdoor.
-In setup mode, press this key to increase the value.

-Press HOLD key to freeze current reading. appears on LCD. Press again to release.
-In Setup Mode, press this key to decrease the value.
-While press HOLD to freeze the reading, it also activate the back light. The back light color was change with WBGT value. See below. Press key again to release and turn off the back light.

-Long press till icon flashing on display to indicate the logging function is in standby status.

Operation

1. POWER ON/OFF
   Press to turn on and turn off the meter. All indicators are shown on the LCD when power on, and then enter measuring mode. You will see the firmware version on the LCD for 1 second while power on.

2. MEASUREMENT
   Slide down the protecting sheath of sensor before measurements.

Display mode
The meter measures TA (Air Temp), TG (Globe Temp), RH (Relative Humidity), and calculates WBGT will be shows on the LCD. (Fig. A)

IN/OUT switch
To measure WBGT without or with direct sun exposure under IN/OUT modes, hold down for more than 1 second to switch.

ALARM / UNIT SETTING
P1.0 WBGT alarm setting
P1.1 alarm buzzer ON/OFF
In normal mode, long press key to enter setup mode. (See below Fig.)When alarm is programmed as ON, appears on LCD. When the WBGT value reaches the alarm threshold, the icon and WBGT value will flash with continuous  beeper sound per second. However, user can short press key to pause the buzzer, the buzzer then sound every 1 min afterward. But, LCD icon will flash until the WBGT value return to normal.
Even if buzzer alarm is OFF, WBGT value flash while reaches the alarm threshold.

P1.2 alarm threshold
The default is setting as 31°C. The adjustment range is 20° C~5°C. Press or key to adjust and press key to confirm. Note : 0.5° C per step When in normal mode, press key can cease the buzzer but bell icon remain flashing until the measured WBGT is returned to normal.
P2.0 Unit setting
P2.1 temperature unit °C /°F switch
Press up/down key to switch between °F and then press key to confirm.

DATALOGGING
Before each recording, connect with computer to setup (see page 8). While ready, long press till flashing on display. During flashing, press to start. To stop logging, long press   till flashing and then press to stop.

BATTERY REPLACEMENT
appears on the LCD when battery voltage gets low. Please replace battery by opening the compartment on the rear of the meter.

AUTO POWER OFF
The meter turns off automatically after 15 minutes non operation.
To override the function, hold down and for 2 seconds to turn on the meter. The LCD will display “n” and then enter  measuring mode.

TRIPOD MOUNTING
The meter can fit on a tripod for long time monitoring. A built-in thread is on the bottom side of the meter.

Datalogger Setup

There is no need to install USB driver or software before operating logging function. Setup logger every time before you want to start logging function.

Connect to computer to setup
Step1:
Connect the logger with any windows computer. Computer will recognize logger as a CD-ROM and pop up new screen for configuration. If not, you may go to file management to click a recognized CR-ROM called “Logger “
Step2:
Double click “Logger configuration tool” to setup the logger. The logger configuration screen offers 8 languages to help you setup easily. The programmable parameters are sampling rate, start delay time and Logger ID.
-The  programmable sampling rate is from 1 min to 2 hours
-The start delay time is from 0 min to 12 hours
Note: By choosing 5 mins, it means the first record will be taken into logger’s memory 5 mins after you pressing the start key of logger.
-Logger ID is a 4 digit number you can use to give each logger a unique property code, such as 0928.  After setting, click Save to synchronize the setting and your PC time zone to datalogger.

Close the setup screen

Step3:
Disconnect logger and leave it to the place where you want to monitor the WBGT. Remember to push down the transparent protection shield.
Press keys to start logging
Step1:
Long press key for more than 1 second to activate the logger into standby status. You will see icon flashing on display.
During icon is flashing, pressing key to start the logging. You will see REC icon flashes on display.
If the logger is programmed as start delay 5 mins, after pressing key, the REC icon will consistent display and then turn into flashing after 5 mins Step2:
It will take 15 ~20 mins to make the WBGT logger to reach equilibrium with testing environment

Press keys to stop logging
To stop recording before memory is full, long press key till H on flash on ice display and then press key during  the icon is still flashing to stop the recording. REC icon will disappear from display There are 12000 records memory space, while memory is full, FULL icon will appear on display.

Connect to computer to read out
The procedure is same like connecting to setup. Pressing download button on setup screen and choose where to save the logged file to. The read out csv report can be opened by windows excel. The saved report contains Configuration Time, Start Time, Start delay, Sampling rate, ID no. and Total records number.
Each record contains Date and time, IN or OUT, TA, RH(%), TG and WBGT
