4-3-2. Output of irradiance (temperature) distribution
Irradiance and temperature distribution is stored inside the UIT-250 (maximum
2 minutes (32 samples/second) or 4 minutes (16 samples/second) for 3840 pieces of
data) and is output using the analog voltage signal.
If placed on the conveyor of the UV radiation hardening equipment with a conveyor
(UNICURE) the irradiance distribution or temperature distribution can be measured.
(1) Perform the "4-2-5. Accumulated exposure amount measurement (1) to (5).
- There measurement range can not be changed if a temperature sensor is con-
nected.
(2) Connect the analog signal output cable that came with the unit to the analog
signal output terminal.
- Connect the orange and white wires of the analog signal output cable respec-
tively to the +,
−
terminals of the recorder device (oscilloscope, pen recorder
etc.).
Important
1. The output impedance of the analog signal output is 1 k
Ω
. In order to
provide a correct measurement it is recommended that the input im-
pedance of the recorder device be greater than 1 M
Ω
.
2. If the input impedance of the recorder device is low, the measured
value may be low.
