4-1 Measurement
Site
For precise measurements, perform measurements in a room (or thermostatic chamber)
where temperature and humidity are controlled to constant levels. Note that the
following types of sites are not appropriate for measurements.
(1) Sites with a sloped floor
(2) Sites with vibration
(3) Sites exposed to direct sunlight
(4) Sites where condensation could form
(5) Sites with a large difference between hot and cold temperatures
4-2 Checking the Power Supply
If Powered by Batteries
The battery box is located on the bottom of the unit.
Remove the cover and install four AA size alkaline batteries.
Note: Use dry cell batteries only. Do not use dry-cell shaped rechargeable batteries.
If Powered by an AC Adapter (optional)
Connect the DC plug from the AC adapter into the power supply socket on the side of
the main unit and plug the AC adapter into the power supply outlet.
4-3 Confirming the Flowrate Conversion
Temperature Setting
When the power supply is switched ON, the flowrate
conversion temperature is displayed. To change the flowrate
conversion temperature, press the [ENTER] key while the
flowrate conversion temperature is still displayed (about
5 seconds). (For instructions on how to change the setting,
see page 16.)
To not change the flowrate conversion temperature, either press the [MODE/ESC] key
while the flowrate conversion temperature is displayed or switch to the main screen
(flowrate measurement) after 5 seconds.
If batteries are left installed when the AC adapter is connected, the system is
powered by the AC adapter.
