Product Introduction

The Split type illuminometer is a professional instrument for measuring light intensity and brightness. It is used in light intensity measurement engineering, quality control, health care, and light intensity measurement in various surroundings, such as factories, schools, offices, transportation, and homes.

Product Features

This split type illuminometer can measure current value, maximum value, minimum value, and difference value of illumination and temperature. It can also hold illumination and temperature data, calculate illuminance integral and average integral, and record data.

• Switch illumination unit (Lux/Fc) and temperature unit (°C/°F).
• Two recording modes: automatic storage of illumination data (up to 2000 groups) and manual storage (up to 60 groups).
• Automatic range and quick response, measurement in environment with insufficient light.
• Screen backlight for darkroom operation.
• Auto-off after no operation for a long time (default span is 10 minutes, can be reset).

Function Description

The illuminometer has two working modes: Normal mode and Setting mode. Each mode has multiple interfaces.

Normal Mode Interfaces:

1. Real-time interface: Displays current measured illumination and temperature values.
2. Max value interface: Records from startup, displays maximum illumination and temperature.
3. Min value interface: Records from startup, displays minimum illumination and temperature.
4. Difference value interface: Displays the difference between the latest measured value and a previously saved value.
5. Holding interface: Freezes the current measured illumination and temperature data.
6. Integral interface: Calculates the integral of the current illumination value over time (unit: hour).
7. Integral averaging interface: Calculates the average illumination value over a specified time (unit: hour).
8. Manual storage interface: Allows manual saving of current illumination values (up to 60 groups). Users can review or delete stored data.
9. Automatic storage interface: Automatically records illumination values at set intervals (up to 2000 groups). Users can review or delete stored data.

Note: Integral operation and automatic storage can be active simultaneously. The 'Σ' and 'REC' indicators will flash when active.

Setting Mode Interfaces:

1. Manual storage setting interface: Set manual storage on/off.
2. Auto storage settings interface: Set automatic storage on/off.
3. Display unit setting interface: Set illumination (Lux/Fc) and temperature (°C/°F) units.
4. Timing shutdown setting interface: Set automatic shutdown on/off.
5. Bluetooth switch setting interface: Set Bluetooth on/off (Bluetooth version only).

Function Operations

1. Turn On/Off

Install batteries. Long press the [POWER] button for 2 seconds to turn on. The device enters the real-time interface after a full-screen display.

2. Backlight On/Off

After startup, short press the [MODE] button in any interface to toggle the backlight. The backlight consumes power and is off by default.

3. Max/Min Value of Illumination and Temperature

In the real-time interface, short press the [MODE] button to switch between Max and Min value interfaces. The screen will display 'MAX' or 'MIN'. Short press [MODE] again to return to the real-time interface.

4. Difference Value of Illumination

In the real-time interface, short press the [DIF] button to switch to the difference value interface. A negative number indicates the real-time value is lower than the saved value, while a positive number indicates it's higher. The screen displays '△'. Short press [DIF] again to return to the real-time interface. The [MODE] button can also be used to return.

5. Data Holding

In the real-time or difference value interface, short press the [HOLD] button to enter the holding interface, displaying 'HOLD'. Short press [HOLD] again to return to the previous interface. The [MODE] button can also be used to return to the real-time interface.

6. Integral Operation

In the real-time interface, press the [REC] button to switch between the integral ('Σ') and integral averaging ('Σ AVG') interfaces. Short press [MODE] to return to the real-time interface from these modes.

Press the [REC] button to start or stop integration. When integration is active, the 'Σ' indicator flashes. The integral value is displayed in Lx·h or Fc·h, and the time span is in hours (h).

Integral Interface Example: Upper screen shows integral illumination (Lx·h), lower screen shows time (h).

Average Integral Interface Example: Upper screen shows average illuminance (Lx or Fc), lower screen shows time (h).

7. Manual Storage Operations
