This programmable timer controller provides precise dual timing, a simple fourbutton interface, and programmable memory to support a range of professional tasks. It is designed for reliable interval control with clear, repeatable results. Key benefits Precise dual timing: T1 countdown supports 0.01 second increments for fine control, while T2 countdown operates in a separate timing channel. Flexible operation: 6 working modes give you multiple preset behaviors to match different tasks without reconfiguring from scratch. Easy parameter setup: Longpress the Set control to enter the P0 parameter and adjust the current setting with the plus or minus controls. Simple user interface: Four buttons provide straightforward operation—plus, minus, set, and start/stop. Quick configuration with presets: Two independent time sets (T1 and T2) let you switch between common timing schemes quickly. Automatic memorization and startup: Setting the P3 parameter can be memorized automatically after about 5 seconds and then run without additional input. Clear time handling: The default unit is seconds; time adjustments wrap around for rapid access (decreasing from 0 moves to the maximum value, increasing from the maximum moves back to 0). What it includes and how it works Interface: 4 buttons—plus, minus, set, and start/stop—for intuitive control. Dual timing: Two independent timing channels, T1 and T2, configured separately to support multistage tasks. Programmable parameters: Access P0 by longpressing Set to modify the current working setting, and use plus/minus to adjust values. Time presentation: Time units default to seconds; the adjustment behavior supports wraparound, enabling fast navigation through the full range. Memory and start: After configuring the working parameter P3, the device memorizes the setting automatically after about 5 seconds and begins operation. Configuration and usage notes Time settings: You can configure two sets of time values (T1 and T2) for flexible task planning. Example configurations show T1 set to a value with 0.01 s resolution and T2 set to a separate value (details shown in the device guide). Example setup sequence: First set the times (for example T1=4.05 and T2=0.1.0). Then configure the P3 parameter; after about 5 seconds, the setting is memorized and the timer starts to run. Time unit behavior on adjustment: The default unit is seconds. When decreasing, the value can wrap to the maximum (for example, 99.9 s); when increasing, it can wrap back to the minimum (for example, 0.0 s) as you hold the button. 23 practical use scenarios Laboratory or manufacturing tasks: Run twostage processes where a primary interval (T1) and a secondary interval (T2) must occur in sequence or concurrently, with quick reconfiguration between test runs. Food preparation or kitchen workflows: Use quick presets for timed steps (marinating, resting, or cooling) and switch between common timings without reentering values. Interval training or supervisory checks: Set up short, precise intervals (T1) for drills and longer rest periods (T2) for recovery, then switch between presets during sessions. Setup steps (illustrative) Step 1: Set T1 and T2 to the required values (for example T1=4.05, T2=0.1.0). Step 2: Configure the P3 parameter. After about 5 seconds, the device memorizes the setting and begins operation automatically. This product maintains a professional, reliable tone with a focus on clear functionality and practical application. It emphasizes the key attributes of function, timing precision, memory capability, and userfriendly operation, while providing concrete scenarios to demonstrate how the timer can be applied in realworld tasks.
