4. Instructions for use
4-2-2. Turning unit off
(1) Push the switch for roughly 1 second.
- Numbers on the display monitor disappear.
- The power is turned off.
4-2-3. Real time irradiance (temperature) measurement
(1) When the UIT-250 is turned on, it enters H range real time irradiance measure-
ment mode.
- The real time irradiance indicator is blinking.
- The average value for 0.5 seconds is indicated on the display monitor.
- When a temperature sensor is connected, the thermocouple temperature is
indicated on the display panel.
(2) Push the switch to change the measurement range.
- The measurement range changes from H range
→
M range
→
L range
→
H range each time the switch is pushed.
- Reference table 1 for display of each measurement range and for full scale
values.
Note, the measurement range is not selected when a temperature sensor is
connected.

(3) When the switch is pushed, the real time irradiance value is held.
- The real time irradiance indicator light turns on.
The hold can be canceled by pushing the switch a second time.
- When in analog output, output is continuous whether the switch is pushed
or not.
