• TO DISABLE THIS FUNCTION, PRESS ON/OFF AND H/T TOGETHER TO TURN ON THE UNIT
• EACH TIME. THE PRODUCT WILL KEEP WORKING UNTIL BEING SHUT OFF BY USERS.
• UNIT
• THE UNIT IS DEFAULT IN ft/min AS MEASUREMENT UNIT FOR AIR VELOCITY. USER CAN PRESS
• THIS BUTTON TO INTERCHANGE THE AIRFLOW VELOCITY UNIT AS THE FOLLOWING:
• ft/min > mph > m/s > km/hr > knots.
• HOLD/TEST
• PRESS THE BUTTON TO FREEZE THE READING FOR RECORDING (BOTH VELOCITY &
• TEMPERATURE), HOLD SIGN APPEARS.
• PRESS AGAIN THE UNIT WILL RESTORE TO REAL TIME MODE.
• °F/°C
• PRESS TO SWITCH THE READING BETWEEN °C AND °F AS TEMPERATURE UNIT.
• AVG/MAX/MIN READING FOR CONTINUE MOVING AVERAGE MEASUREMENT (SINGLE POINT)
• a) PRESS ONCE THE UNIT WILL SHOW THE CONTINUE MOVING AVERAGE MEASUREMENT OF
• VELOCITY (AVG), MAXIMUM MEASUREMENT (MAX) AND MINIMUM MEASUREMENT (MIN) AS
• FOLLOWING:
• AVG > MAX(BOTH TEMP & VELOCITY) > MIN(BOTH TEMP & VELOCITY) > REAL TIME READING
• b) RELEVANT SIGN APPEARS ON THE DISPLAY AND READING UPDATE PER SECONDS.
• c) TO CLEAR VALUE, PRESS AND HOLD THE KEY FOR 3 SECONDS, 2 SUCCESSIVE BEEPS
• SOUND IS
• GIVEN OUT.
• AVG (MULTI POINT)
• a) HOLD THE UNIT IN POSITION, PRESS THE HOLD BUTTON TO FREEZE THE READING (BOTH
• VELOCITY AND TEMPERATURE).
• b) THEN PRESS MEM BUTTON TO SAVE THE READING. (A SINGLE BEEP IS GIVEN OUT FOR
• EVERY SUCCESSFUL SAVING). MEM 1 DISPLAYS REPRESENTING ONE READING IS SAVED.
• c) REPEAT STEP (a) (b) TO SAVE ANOTHER READING, MEM 12 DISPLAYS REPRESENTING 2
• READINGS ARE SAVED.
• d) CONTINUE TO DO SO UP TO 10 SETS OF READING CAN BE SAVED.
• e) ONCE ALL MEASUREMENT HAVE BEEN SAVED, PRESS AVG (MULTI POINT) BUTTON, THE
• UNIT WILL DISPLAY THE AVERAGE AIR VELOCITY FROM MEMORY AND AVG SIGN APPEARS.
• MEM (MEMORY RECALLING)
• a) Press THE MEM BUTTON, ALL SAVED READING (BOTH TEMPERATURE & VELOCITY) WILL
• BE SHOWN, STARTING FROM THE 1ST READING (i.e. MEM 1) TO THE 10TH READING (i.e. MEM
• 10).
• b) PRESS AND HOLD THE MEM BUTTON FOR 3 SECONDS TO CLEAR ALL SAVED READINGS.
