1, power on, the key: press the "open" button to open, LCD display measurement status; press the "off" key, the instrument off, cut off the power.

2. The quick connector can be checked by connecting the tested instrument with the high pressure hose.

3. When using the pressure calibrator, please screw the instrument into the “standard instrument” interface of the manual pressure pump.

4. School zero key: Before measurement, click: “Zero zero” key, the instrument automatically collects the zero value of the sensor and sends it to the processor CPU for processing to ensure that the measured data of the instrument is the actual pressure value.

5. Pressure key: After power on, the lower right corner of the LCD displays the pressure unit of the instrument. If you press the "Unit" key during use, the LCD will be displayed as any unit in "Psi, Bar, mmHg, Kgf/cm2". "Pressure" button, the meter automatically switches to the factory setting pressure unit file. When it is necessary to display the measurement current, when the pressure calibrator display unit is MPa (or KPa), press the “Pressure” button, and the corresponding current indicator on the panel lights up, which means the measurement current status.

Pressure calibrator pressure range and pressure pump configuration: pressure calibrator pressure range according to the user's requirements configuration, if the pressure calibrator with vacuum, pressure range up to -95KPa~2.5MPa, this check The instrument only needs to be equipped with a built-in pressure pump. Generally, pressure calibrators within 0 to 6 MPa can be equipped with built-in pressure gauges. Pressures in excess of this range require a benchtop pressure pump.
