<Caution>
-
Make sure to cut the power supply to the main unit before switching the current/voltage output.
-
Output can be set by either voltage output (0 to 5V) or current output (4 to 20mA).
(The factory default setting is provided with current output.)
1.
Current / Voltage output can be switched by the DIP switch.
2.
Setting of the output range can be made by the rotary switch (setting can be changed also while the
power is supplied to the main unit).
3.
Output range can be selected from the following five (5) air velocity ranges. Select the optimum
range according to the air velocity range to be measured.
No.
