MAX/MIN/AVG
1. Press the MAX/MIN button to cycle through
the maximum, minimum and average
measurements of Ambient Temperature,
Global Temperature and Relative Humidity
since the instrument was powered on.
2. To clear the maximum, minimum and average
readings, press and hold the MAX/MIN
buttonuntil"CLr"appearsatthebottomof
theLCD.Theinstrumentwillautomatically
return to normal operation once the readings
have cleared.
Note:WhenthemeterisMAX/MIN/AVGfunction,theHOLD and MODE
buttons are disabled.
Indoor/Outdoor Temperature Mode Selection
When in the WBGT mode, press and hold the UNIT button to toggle
between indoor or outdoor temperature. The instrument automatically
calculates the measurement using the following parameters:
1. Outdoor formula WBGT = 0.7Tw (wet bulb temperature) + 0.2Tg
(globe temperature) + 0.1Td (air temperature).
2. Indoor formula WBGT = 0.7Tw (wet bulb temperature) + 0.3Tg
(globe temperature).
Switching the Temperature Unit of Measure
Press the UNITbuttontoswitchbetween°Cand°F.
Switching the Pressure Unit of Measure
Press the BKLT button to change the pressure measuring unit.
(hpa--> inHg--> mmHg).
Temperature Display Modes
Press the MODE button to toggle through the GT (Globe temperature) -->
WBGT temperature --> HI (Heat index) --> DPT (Dew point) --> WB (Wet
bulb temperature measurements).
