Maintenance and Cleaning
The power units are maintenance-free apart from the need to repla-
ce the batteries and cleaning it once in a while. Use a clean, lint-
free, antistatic and dry cloth to clean the device. Do not use any
abrasive or chemical agents or detergents containing solvents.
Replacing the battery
If the battery symbol appears in the display, the batteries have to be
replaced as soon as possible to prevent inaccurate measurements.
Proceed as follows to replace the batteries:
Switch off the measuring instrument.
- Loosen the battery compartment screw on the back off the unit,
and slide the lid off in the direction of the arrow.
- Replace the flat battery with a new one of the same type (1604A).
- Replace the battery compartment lid in the reverse order.

Initial Operation
Inserting the batteries
Before the initial operation of this meter, you must first install a new
9V block battery. Instructions for installation can be found in the
"Maintenance and Cleaning" section.
Connecting the flow sensor
A flow sensor is included with this meter. Connect the 4-pin sensor
plug to the "INPUT" socket on the meter, with the flat side of the
plug facing downwards to the bottom side of the housing. Make
sure that the plug is sitting firmly in it's socket, otherwise inaccurate
readings could result.
Making a meter reading
Make sure that the mounted wind sensor is facing
parallel to the direction of the wind. If the wind sen-
sor happens to be twisted in the wrong direction,
inaccurate readings will result.
Make sure that you are not blocking or altering the
wind flow with your body or parts of your body.
This meter also has several extra functions that make measuring
and handling easier.
The extra functions include:
Auto power OFF function
To save on the unnecessary usage of battery power, an automatic
switch-off function has been built-in. The meter will be automatical-
ly switched off, if no button is used within a 10 minute limit. The
meter can be switched straight on again with the "POWER" button.
