Operation
1. Turning on and o your Meter
a. Press the button to turn on your meter. After 10 minutes without any operation the meter will power o.
b. To override the Auto Power O hold down the Set button then press the button to turn on. Warning, the meter will
stay on until the battery runs out unless you turn o by holding down the button.
2. Selecting Air Velocity & Temperature Units of Measure
a. Quick short presses of the Unit Button will select the wind speed units of measure view (m/s, ft/min, knots, km/h, mph).
b. An extended press of the Unit Button will select the temperature units view °C / °F.
3. Selecting Type of Reading (Maximum, Minimum , Average, Hold, Normal)
a. A short press of the Set Button will select MAX/MIN/AVG reading. When none are displayed on the LCD you are viewing
the current normal reading.
b. An Extended press of the Set Button will hold the reading.
4. Backlight
a. The Backlight will turn o after 10 seconds without use. To override hold down the Units Button then press the Button.
The Backlight will then illuminate constantly.
5. Relative Humidity (RH)
Relative humidity is the amount of moisture in the air compared to what the air can “hold” at that temperature. When the air can’t
“hold” all the moisture, then it condenses as dew. RH is eected by wind speed, i.e. the more powerful the wind the less moisture
there will be in the air.
6. Calibration Mode ! WARNING! THIS SHOULD ONLY BE CARRIED OUT BY TRAINED PROFESSIONALS AT AN ACCREDITED
CALIBRATION FACTLITY!
In the event where calibration is required, please follow these steps:
Step 1: Turn on the meter,then press Set Button and Units Button at the same time to enter the calibration;
Step 2: Press Units Button to choose the Mode 1-wind speed;Mode 2-temperature;Model 3-humidity; then press Set Button
to enter the method.
Step 3: Press Units Button to choose the jumping number, Press Set Button to adjust the reading.
Step 4: Press the Power Button to store the setting.
Warning! Your warranty is void if this procedure is carried out by an untrained individual and/or at a non-accredited
calibration facility which is not universally recognized.
Battery Replacement
If the meter does not power on as usual or the low battery icon appears on the LCD, replace with a new CR2032 Lithium
Battery. To do this, turn the battery compartment cover in a counterclockwise direction to remove it.
Remove the old battery and insert a new battery face up, with the bottom side in contact with the two pins.
Dispose of the battery in an environmentally safe and sound manner at a recycling point.
DO NOT DISPOSE OF IN YOUR BIN!

Caution
Trouble Shooting
Warranty
• This meter is accurate at low and mid-range air speeds. Consistent use at very high speeds, i.e. from the window of a fast
moving car will damage the impeller’s bearing and reduce accuracy.
• This meter is not a personal safety device.
1. Power on but no display or the display disappears
a. Check the battery is in place with good contact to the pins and the correct way up.
b. Remove battery for one minute and re-install.
c. Replace the battery.
2. For all other issues please contact your supplier.
This meter has a one year warranty for a period of one year from date of purchase.
This warranty covers normal operation and does not cover batteries (including leaks), misuse, abuse, alteration, tampering, neglect,
improper maintenance or improper calibration. Nor can the warranty be used as an excuse for a false claim simply because you have
changed your mind after the initial 14 day period.
Proof of purchase is required for warranty repairs.
