Not only can split type illuminometer measure current value, maximum
value, minimum value and difference value of illumination and temperature,
but also hold illumination and temperature data, calculate illuminance
integral and averageintegral averaging and record data.
1.Switch illumination unit and（Lux/Fc)temperature unit（℃/℉）
2.Two recording modes: automatic storage of illumination data (up to
2000 groups) and manual storage (up to 60 groups)
3.Automatic range and quick response, measuremwent in environment
with insufficient light.
4.Screen backlight for darkroom operation.
5.Auto-off after no operation for a long time (the default span is 10 mins
and can be reset)

There are two working modes of illuminometer, normal mode and setting
mode. Each working mode has multiple interfaces:
(1) Normal mode
1. Real-time interface: display current measured value of illumination and
temperature.
2. Max value interface: record from startup, display maximum value of
illumination and temperature.
3. Min value interface: record from startup, display minimum value of
illumination and temperature.
4. Difference value interface: display the difference value between the
latest measured value of illumination and enter the saved value when
first entering the interface.
5. Holding interface: when the current measured value 󰾬󰾬of illumination and
temperature 󰾬󰾬is no longer updated, the data remains unchanged.
6. Integral interface: the integral of the current illumination value against
time(unit: hour).
7. Integral averaging interface: within the specified time(unit: hour), the
average of illumination value integral against time.
8. Manual storage interface: you can manually save the current illumination
value by pressing the button and can check the total groups of manually
stored data (storage mode), with the maximum capacity of 60 groups.
You can manually refer to certain illumination data or delete all manually
stored data.
9. Automatic storage interface: you can set the timing period, and the
illumination value will be automatically recorded; you can refer to the
total groups of automatically stored data (storage mode), with the
maximum capacity of 2000 groups; you can manually refer to certain
illumination data or delete all auto-stored data.
Note: The integral operation and automatic storage operation can be
turned on at the same time. If successful, "Σ" and "REC" at the top of
the screen will flash.
(2) Setting mode:
1. Manual storage setting interface: set manual storage on and off.
2. Auto storage settings interface: set automatic storage on and off.
