I. Core Calibration Equipment
High-Precision Process Calibrator/Thermal Engineering Handbook: Supports high-precision output and measurement of voltage, current, thermocouple, and RTD signals, with an accuracy level ≥ ±0.05%FS. It is the core equipment for routine accuracy calibration of hot runner signal generators.
Multi-Channel Digital Oscilloscope: Bandwidth ≥ 100MHz, supports at least 4 channels for simultaneous acquisition. Used to compare the phase difference of multi-channel output waveforms and accurately measure synchronization deviation.
High-Precision Frequency Counter: Resolution ≥ 0.1ppm. Used to verify the output frequency of the onboard crystal oscillator of the main signal source and confirm that the clock reference accuracy meets the standard.
Standard Temperature Source: Used in conjunction with thermocouple/RD signal calibration to verify the accuracy of the temperature simulation output of the hot runner signal generator.
II. Auxiliary Tools
Equal-Length BNC Coaxial Cables: Multiple BNC cables of identical length and specifications are used to establish a synchronous trigger link, avoiding additional deviations introduced by transmission delay differences.
High-precision BNC synchronizer distributor: 1-to-N specification, used to evenly distribute the master channel synchronization trigger signal to all slave channels, reducing link node loss.
Anti-static wrist strap: Worn during industrial field operations to prevent electrostatic damage to the signal generator's internal precision circuitry.
Terminal cleaning tool: Used to clean the oxide layer from BNC terminals and signal interfaces, eliminating signal transmission deviations caused by inconsistent contact resistance.
Insulation resistance meter: Used to test the insulation performance of the signal generator before calibration, confirming that the equipment's electrical safety status is normal.
This toolkit fully covers all the needs for routine accuracy calibration and multi-channel synchronization deviation calibration of hot runner signal generators, adaptable to industrial field operation and maintenance scenarios.
