    Digital pressure differential meters are widely used to measure the pressure of fans and blowers, filter resistance, wind speed, furnace pressure, plate differential pressure, bubble water level and liquid amplifier or hydraulic system pressure, but also for air-gas ratio control and automatic valve control during combustion, as well as blood pressure and respiratory pressure monitoring in healthcare equipment.
    today's small editor to take you to understand the use of digital differential meters and precautions.
    the use of digital pressure differential meter: a, the instrument level on less dust, small vibration of the test platform.
    b, should be connected to warm up more than 30min before use.
    c, the zero-measurement selection of the digital differential meter: the switch is placed at the zero point, and the zero point is turned to zero.
    d, digital pressure differential meter in the unit of measurement after the detection of zero points can not be easily adjusted.
    , the pressure connection must ensure that the pressure to be measured is below the allowed limit.
    f, select according to the range of pressure under test and press the appropriate range stop.
    , place the zero-point-measurement switch in the measuring position, and start measuring.
    the range and the display shines, the range should be raised.
    note: a, the correct choice of digital pressure differential meter.
    when selecting the pressure gauge measurement range, the measured pressure does not allow the permissible overload capacity beyond the measuring range, otherwise it affects zero points and sensitivity.
    b, remember that solid particles or other hard objects enter the lead tube to avoid damaging the sensor.
    c, pressure to be slow, excessive impact will cause fatigue failure of the pressure sensor element, d, do not exceed the use of temperature range, otherwise it will cause a decrease in accuracy.
    , the pressure medium must be adapted to the material of the pressure sensor, otherwise the sensor will be damaged.
    f, indemerable digital pressure meter should be sent once a month to keep it in good condition at all times.
