2 seconds BKLT button again. SET AREA VALUE: While at VOL mode, press SET button to set area value, the meter may store up to each 5 square size and round size of areas. i.e. Total 10 areas storage for easier and faster to get area for calculate air volume. Press and hold SET button + short press POWER button quick select stored area(1L1/1d~5L1/5d) (While at VEL mode). 1. VEL mode operation : ( While at VEL mode ) VEL icon shows on the bottom layer. a) Press HOLD , HAND ON/OFF button to hold current VEL value. b) Press MODE button to cycle viewing Temperature, RH%, DP (Dew Point) and WB(Wet bulb temperature). c) Press UNIT button to change the unit of Temp., DP, WB d) Press and hold UNIT for 2 seconds to change velocity unit(M/S,FT/M) e) Press POWER button to select FT f) Press SET button to save velocity reading, LCD shows and stores the number with the readings and “REC” icon appears then disappear after data stored. 2. VOL mode operation: ( While at VOL mode ) FLOW icon shows on the bottom layer a) Press HOLD , HAND ON/OFF button to hold current VOL value. b) Press MODE button to cycle viewing Temperature, RH%, DP(Dew Point) and WB(Wet bulb temperature). c) Press UNIT button to change the unit of Temp., DP, WB d) Press and hold UNIT for 2 seconds to change velocity unit e) Press POWER momentarily to change are unit . f) Press SET button to enter set area value mode ...

or FT . d) To edit value of area, press momentarily the BKLT button to change with ‐0.01 ( Max. area value is 99.99 ),i.e. To decrease the stored area value. If no value is stored, press BKLT button, it won’t active and still remain as 00.00 e) Press HOLD button to change area value with +0.01 (i.e. Increase the value) f) Press and hold BKLT button for 2 seconds to change area value with ‐0.1 once ( i.e. Decrease the value), or keep pressing and holding HOLD button to quick select the numbers. Release the button for the number you desired. g) Press and hold HOLD button for 2 seconds to change area value with +0.1 once (i.e. Increase the value), same operation as decreasing value per step f) h) Press SET button to automatically save and return to VOL mode 3. REC mode operation ( While at RECORD mode ) Long press MODE to go through Vol. mode then long press MODE again to enter REC mode. a) Press HOLD button to increasingly recall stored air velocity reading +1 b) Press BKLT button to decreasingly recall stored air velocity reading ‐1 c) Press and hold SET button for 2 seconds to clear stored readings d) Press MAX/MIN button to circularly viewing Maximum. Minimum. Average readings from powered on , press MAX/MIN button again to return to record mode e) While viewing Max/Min/Avg readings, you may press UNIT button to change AVG unit, press UNIT button again to return ...
