3. Measurement Mode
3.5 Memory Capacity
Measurement data is stored per page. On top of the each page the
measurement condition is stored. Therefore, the more pages you
save, the less data you can store.
Below describes how to figure out how many pages of data can be
stored when you know how many data you want to take.

(1) Measurement Starting Date (08. 7. 1 10:40)
(2) Measurement Item (air velocity, air temp VT)
(3) Measurement
(Average: AVE, Interval: INT, Air Flow: FLW)
(4) Sampling Time (S-TIME(S))
(5) No. of Data (DATA (N))
(6) No. of Measurement Points (POINTS)
(7) Measurement Interval INT (min) or Duct Area AREA (m²)
(8) Air Velocity Data and Air Temperature Data
Internal Memory
P = 4770 / (24 + 4 × N)
[Example] When N is 10, P is 74 according to the above formula.
