I. Hardware Link Consistency Guarantee
All synchronization trigger lines use BNC coaxial cables of identical length and specifications to avoid synchronization deviations caused by transmission delay differences between different cables.
A 1-to-N high-precision BNC synchronization distributor replaces multiple T-connectors, reducing node losses in the signal link and ensuring synchronous distribution of trigger signals to all channels.
All terminals undergo pre-treatment with oxidation cleaning to avoid differences in trigger signal transmission delays caused by loose connections or inconsistent contact resistance.
II. Clock Reference Unification Guarantee
Strictly adhere to the "master-to-slave" power-on sequence: first start the master signal source and set its clock source as internal, serving as the sole clock reference for the entire system.
All slave signal sources are uniformly set to external clock sources, forcibly locking and following the master signal source's clock reference, completely eliminating drift deviations of independent clocks for each channel.
Every 100,000 production cycles, the master clock source undergoes accuracy calibration to prevent clock reference drift due to long-term operation.
III. Trigger Mechanism Consistency Guarantee
All channels are configured with identical trigger logic: the main channel trigger source is set to "Manual," and the trigger output is set to "Rising Edge"; all slave channels trigger sources are set to "External," and the trigger input is set to "Rising Edge."
The BURST function of all channels is uniformly set to "Infinite" mode to ensure all channels enter the output standby state synchronously, preventing any single channel from starting prematurely.
Different channels must not use different trigger modes to avoid synchronization timing misalignment caused by differences in trigger logic.
IV. Deviation Calibration and Fixation Guarantee
The output signals of all channels are acquired using a dual-channel or higher oscilloscope. The time phase difference is finely adjusted channel by channel using the delay parameter in the Burst menu until the synchronization deviation of all channel signals is ≤0.01s.
All devices enter the Utility menu and set the power-on startup option to "Last Value." The device automatically loads the configured synchronization parameters upon the next power-on, eliminating the need for repeated settings and preventing human error from disrupting the synchronization state.
A multi-channel synchronization parameter archive is established to record the parameter values configured for each synchronization, forming a parameter iteration and optimization record to maintain stable synchronization accuracy over the long term.
V. Abnormal Redundancy Protection
The system is equipped with a synchronization status monitoring function. If any channel trigger signal is lost, the system automatically pops up an alarm to prevent continued operation after a single channel loses synchronization, thus avoiding invalid verification results.
A 10% synchronization delay adjustment redundancy is reserved to cope with minor delay shifts caused by slight hardware aging after long-term operation. Synchronization deviations can be quickly corrected without rebuilding the link.
This end-to-end protection solution is fully adaptable to industrial scenarios involving multi-channel batch verification of hot runner systems. It can maintain a stable, high-precision synchronization state across multiple channels over a long period, avoiding deviations in channel verification results caused by synchronization loss.
