Microcomputer measurement and control instrument, gas and electricity meter

Microcomputer measurement and control instrument, gas and electricity meterWe mainly provide customized non-standard measuring tools based on customer needs. For example, non-standard ring gauges, plug gauges, pneumatic gauges, spline gauges, irregular gauges, thread depth touch gauges, taper gauges, etc. Design and produce according to requirements.

1、 Preparation before measurement (key prerequisite)

1. Environment and gas source

• Environment: Temperature20±1℃Humidity40%–60%No vibration, no dust, no oil stains.

• Gas source: pressure0.4–0.6 MPaConstant, throughDrying+filteringNo oil or water to prevent nozzle blockage.

• Instrument: placed inSeismic platform, probe and workpiece surfaceverticalThe workpiece is clean and free of burrs and oil stains.

2. Installation and startup

• Probe: screw into the installation hole to ensureNo looseness or air leakage.

• Power on: Turn on the power and wait3-5 minutesPreheating and system initialization.

• Parameters: Enter the menu, setMeasurement unit, range, resolution, upper and lower limits of tolerance.

2、 Calibration (mandatory to ensure accuracy)

1. Two point calibration (standard part method)

1. Zero setting: Place the probe inLower limit standard componentsPress' zero/lower limit 'to adjustZero position knobAlign the displayed value with the standard value and lock it.

2. School upper limit: probe insertionUpper limit standard partsAdjust according to the 'school upper limit'Magnification knobMatch the displayed value with the standard value.

3. Review: Repeat the insertion of upper and lower limit standard parts untilBoth points are accurateSave calibration.

2. Quick calibration (daily)

• Only insert the lower limit standard parts and press' zero 'to reset them;Replace the probe/gas source/environmental changesTwo point calibration must be performed.

3、 Measurement operation (core steps)

1. Positioning: Probeslowly approachWorkpiece, maintainverticalAvoid colliding with the nozzle.

2. Reading: To be displayedstableRead the numerical value afterwards; Can record or export data.

3. Batch: When measuring continuously,Every 10-20 piecesVerify the zero position once using standard parts.

4. Judgment: According to the preset tolerance,Green=qualified, red=out of tolerance.

4、 Closing after measurement

1. Shutdown: First turn off the gas source, then turn off the instrument power.

2. Cleaning: Gently blow the nozzle of the measuring head with compressed air to clean the instrument and workbench.

3. Storage: probe cover protective cover, instrument cover dust cover.

5、 Common problems and precautions

• Unstable data: checkGas source pressure, leakage, probe perpendicularity, workpiece cleanliness.

• Indication deviation: redoTwo-point calibrationCheck if the standard parts are worn.

• Nozzle blockage: Use a fine needle to gently pass through,Do not stab with hard objects.

• Strictly prohibited: probeImpact workpieceGas source with oil and water, severe environmental vibration.
