Pressure calibratorIt is a precision equipment used for calibrating instruments such as pressure transmitters, pressure switches, and pressure gauges. Common faults involve modules such as pressure sources, sensors, electrical signals, and mechanical components. The following are maintenance measures to prevent malfunctions:

1. Daily maintenance

• Cleaning:
  Wipe the pressure interface with anhydrous alcohol after each use to prevent oil stains from clogging.

• Moisture and shock resistance:
  Store in a dry oven to avoid falling (especially for precision sensors).

• Regular self inspection:
  Monthly atmospheric check for zero deviation (should be ≤ 0.01% FS).

2. Replacement cycle of key components

3. Calibration cycle

• Verification device itself:
  Every year, it is sent to the metrology institution for traceability (standard: JJG 882-2004).

• Pressure module:
  Cross comparison is conducted every 6 months (validated using a standard table).
