3-1 MEASURING PREPARATION
3-2 Wind velocity Measurement
Directivity point of the probe towards the windward exactly.
The tip of the probe will detect the wind velocity. Press the POWER button to turn the
Instrument on, The "L" range is selected to measure the wind velocity.
The Automatic range-switching function operates from "L"to "M" or "H" when a wind
The wind velocity is reading on Large LCD display , Analog meter simultaneously and
*Use Analog meter reading in case of severe fluctuations.
*The measuring function display is blinking during the "HOLD"
3-3 Static pressure Measurement
Press the POWER button to turn the Instrument on,Select the "m/s Pa" button to measure the
Static pressure and confirm indication of "Pa or kpa" on the measuring function display then
the static pressure will be displayed on the digital display , analog meter simultaneously and
Static pressure adapter:
Slightly loosen the unit of the accessory static pressure adapter ,insert the probe as far as possible ,
align the rear fitting of the probe and the white line on the static pressure adapter,and tighten the
nut. Place the orifice in the center of the rubber plate of the adapter on to the location where the
pressure is to be measured. For Example :A hole with diameter of about 10mm in a duct.
Positive pressure can be measured with the orifice at the head of the probe,while negative can
be measured with the orifice at the side.
The same number as the detection unit is attached to the adapter static pressure.
The measured values 󳆎󳆎can not be guaranteed when used in combination with those other numbers.
Please use the same number of means be measured with the orifice at the side.
Use the accessory probe holder for measuring near the ceiling and at other high locations
(free retraction and extension between 0.2 mand 1m).
If the Digital Display does not switch on when the POWER button is pressed or when BATT.CHECK
button is pressed the disply shows "B0" ,Repalce the batteries
1. Remove the battery compartment.
2. Replace the 4 "AA"1.5V batteries observing polarity
* If the meter will not be used for long time, remove the batteries
If the probe should become damaged,Please contact the nearest sales office or
Hiyoshi Electric company .to buy a new one .
*The measuring values can not be guaranteed when a probe of a different model is used.
The pointer of the analog meter should aways be at the lower end (left end) of the scale before
power on.
lower LCD sub-disply shows the temperature reading.
Taking Measurements
Press the POWER button to turn the instrument on .
Press the POWER button to disply the model name (90A,90B,90C) and Battery indicator (b0-b9)
Remove the probe from the clip, hold the probe by the handle in the area to be measured.
velocity corresponding to the "M"or "H"range is detected.

1The probe should never be exposed to temperatures of 100℃ or more.
2. In case of "Out of Range"

As measuring errors will be caused by clogging of the hole or the net at the tip of the probe,they
should be cleaned from time to time with a soft hair brush or by washing with alcohol,bezine,etc.
5. The digital display shows strange characters sometimes instanneously .It is no problem for
LCD'S character.
6. Auto switch off : 20 min.after last key press .
