1 Introduction
Thank you of purchasing a PCE-A420 cup vane anemometer from PCE Instruments.
A handy cup anemometer with digital display. The great advantage of the cup anemometer is no doubt in
the possibility that you do not have to hold the cup anemometer exactly in the wind direction. Normal
vane anemometers have the disadvantage that they only measure exactly when the impeller is held in the
wind direction. The very smooth cup anemometer already responds to small flow rates.
2 Safety

5 Measuring Procedure
5.1 Wind Speed Measurement
Turn on the meter by pressing the “Power Button” (3-2, Fig. 1) momentarily. Pressing the “Power- Button”
(3-2, Fig. 1) momentarily again to turn off the meter.
1) Use the hand to hold the meter vertically. The “Cup Vane” (3-1) will be rotated and shows the
measured the wind speed value on the “LCD Display” (3-5, Fig. 1).
5.1.1 Unit Change
1) Meter defaults unit value is “m/s”. Meter unit value can be changed to “m/s, km/h, knot, ft/min,
mile/h
2) The method to change the unit: Press the “Unit Button” (3-3, Fig. 1) continuously, after several
seconds the unit will change from m/s, km/h, knot, ft/min, mile/h” in sequence. When the desired
unit is reached, release the finger from the “Unit Button” (3-3, Fig. 1), the new unit will be saved
into the memory circuit and will be shown when the device is turned on again.
* When the display shows “HOLD“ (refer 5-3) or “REC” (refer 5-4), the unit cannot be changed.
5.1.2 Data Hold
During the measurement, press the “Hold Button” (3-3, Fig.1) momentarily to hold the measured
value. The LCD will show a “HOLD” symbol.
Press the “Hold Button” once again to release the data hold function.
5.1.3 Data Record (Max., Min. reading)
1) The data record function records the maximum and minimum readings. Press the “REC Button” (
3-4, Fig.1) momentarily to start the data record function, the display shows “REC”.
2) With the “REC” symbol on the display.
a) Press the “REC Button” (3-4, Fig.1) momentarily again, the “REC MAX” symbol along with
the maximum value will appear on the display.
b) Press the “REC Button” (3-4, Fig.1) momentarily again, the “REC MIN” symbol along with the
minimum value will appear on the display.
* When display shows “REC MAX” or “REC MIN”, press the “Hold Button” (3-3, Fig.1)
momentarily, this will delete the max. (min.) value, the display will show the “REC.” only and
execute the memory function continuously.
c) To exit the memory record function, press the “REC” button for 2 seconds at least. The
display will revert to the current reading, and will not to show “REC”.

5.2 Data Logger
The meter can save max. 100 point data into the memory circuit
5.2.1 Save data
1) Turn on the meter.
2) Press the “REC Button” (3-4, Fig.1) momentarily, shows “REC” on the display.
3) Press the “Logger Button” ( 3-2, Fig.1) momentarily will save one measuring value to memory,
display will show:
4) To exit the memory data logger (record) function, press the “REC” button for 2 seconds at least.
The display will revert to the current reading, and will not show “REC”.
5.2.2 Call Data
1) Turn on the meter. Press the “Hold Button” (3-3, Fig.1) momentarily, LCD shows “HOLD”.
Following, press the “REC Button” (3-4, Fig.1) momentarily, display shows:
Uses “▲ Button” (3-2, Fig.1) or “▼Button”(3-4, Fig.1) to call the data what are already saved into the
memory.

Note:
* Duringcall the data, the unit display will be flashed.
* Press “Hold Button” (3-3, Fig.1) will exit the data call function.
5.2.3 Delete Data (Empty the memory)

2) Press the “REC Button” (3-4, Fig.1) continuously and do not release, at the same time press the “
Power Button” (3-2, Fig.1) momentarily, the display will showfollowing screen, then release both
fingers from the buttons.
Press “▼Button” momentarily, display shows:
Press “↵Button” (3-3, Fig.1) momentarily, the display shows:

Nowall saved data´s are deleted, memory is empty.
6 Battery Replacement
Replace the batteries when the left corner of the LCD displays shows the low battery icon “
“, using 4 fresh 1.5V (UM4, AAA) batteries.
