Installation and Maintenance

Before the first use, the calibrator should be unpacked on a clean, level workbench and inspected for any shipping damage. Verify that the stainless‑steel base plate is free of dents and that all four pressure‑generation handles move smoothly without binding. Connect the supplied liquid reservoir to the inlet port using the provided hose, ensuring that the lock‑needle is fully engaged to prevent accidental leakage. Fill the reservoir with the chosen fluid—either mineral oil for high‑temperature applications or de‑ionised water for low‑pressure tests—up to the marked fill line. Tighten the reservoir cap securely and purge the system by cycling the pressure handles several times to remove trapped air bubbles. Once the fluid circuit is sealed, attach the appropriate pressure adapter kit to match the test device’s fitting, and confirm that the adapter threads engage without cross‑threading. Finally, power the unit by connecting the supplied AC adapter, and allow the internal electronics to initialize for approximately five minutes before performing the first calibration run.

Operating a high‑pressure calibrator demands strict adherence to safety protocols to protect personnel and equipment. Always wear appropriate personal protective equipment, including safety goggles, chemical‑resistant gloves, and a lab coat, when handling oil or water under pressure. Ensure that the work area is well‑ventilated and that any combustible materials are removed from the vicinity of the calibrator, especially when oil is used as the test fluid. Before each test, confirm that the pressure adapters are correctly matched to the device under examination and that the sealing surfaces are clean and free of debris. Never exceed the maximum pressure rating of 700 kg/cm², and never operate the unit without the liquid reservoir properly filled, as dry operation can cause internal component damage. In the event of an unexpected pressure spike, the built‑in safety valve will automatically vent excess pressure, but operators should still be prepared to manually engage the emergency shut‑off lever if needed.

After installation, the calibrator must be verified against a primary standard to confirm its accuracy before it is used for critical measurements. Place a certified reference gauge on the calibrator’s pressure port and apply a series of incremental pressure steps covering the full 0‑700 kg/cm² range. Record the indicated values and compare them to the known reference values, noting any deviation. The device’s built‑in software allows the operator to input the reference data and automatically calculates correction factors for each pressure point. If the deviation exceeds the allowable tolerance of ±0.2 % of full scale, recalibrate the instrument by adjusting the internal zero and span settings according to the manufacturer’s service manual. Once the correction factors are applied, repeat the verification sequence to ensure that the calibrator now meets the specified accuracy requirements.

Routine preventive maintenance consists of a quick visual inspection and functional test performed on a monthly basis. Check the condition of the pressure‑generation handles for signs of wear or looseness, and verify that the lock‑needle seals are still intact by gently pulling on the needle without applying excessive force. Inspect the liquid reservoir for any signs of corrosion, cracking, or contamination, and replace the fluid if it appears discoloured or contains particles. Confirm that the pressure adapters are free of burrs and that the threads engage smoothly. Run a short pressure cycle from zero to a mid‑range value of 350 kg/cm² and back to zero, observing the display for any irregularities in the pressure readout. Document any anomalies and schedule a service call if the instrument does not return to baseline performance.

If the calibrator displays an error code or the pressure reading fluctuates, follow a systematic troubleshooting procedure. First, power cycle the unit by disconnecting the AC supply for thirty seconds and then reconnecting it, which can clear transient faults. If the error persists, consult the user manual’s diagnostic table to identify the specific code and recommended corrective action. Common issues include a blocked inlet port, which can be cleared by flushing the reservoir with fresh fluid, or a worn seal on the lock‑needle, which should be replaced using the spare seals supplied with the instrument. For more complex problems such as electronic sensor failure, contact an authorized service centre where trained technicians can replace the internal modules under warranty conditions.

The calibrator is designed with modular components that can be serviced or upgraded without returning the entire unit to the factory. Spare parts commonly stocked include the lock‑needle assembly, O‑ring seal sets, pressure‑generation handle grips, and the liquid reservoir cap.
