MEASUREMENT PROCEDURES
Non-Sleep Mode Selection
To save battery life, the WBGT Heat Stress Meter
turns off automatically after 20 minutes of inactivity.
To monitor the environment continuously for longer
periods, you may override this feature:
1. With the meter turned off, press and hold the
SET and MODE buttons simultaneously for 2
seconds. The meter displays and enters
Non-Sleep measurement mode.
2. When you have completed your readings, slide
the cover back up to its protective position and
press the SET button to turn off the unit. Non-
Sleep mode is cancelled and the unit is reset to
turn off automatically after 20 minutes.
MEASUREMENT PROCEDURES
Alarm Threshold Selection
The WBGT Heat Stress Meter features an audible
alarm. You can adjust the alarm values as required
within the range of 68.0°F-99.0°F (20.0°C-37.2°C).
If the meter reaches the set alarm value, the unit
emits an audible alarm (continuous beep at about
70dB) to let you know that your threshold has been
exceeded.
The alarm stops when the reading falls below the
set threshold or when you turn off the meter. To set
your alarm:
1. With the meter turned off, press and hold the
SET button for 2 seconds. The LCD displays a
temperature setting with the first digit flashing.
