  • (*2)In case of calibration for compound pressure, calibration is performed only for the positive pressure, and only measurement data are given for the negative pressure. In this case, acceptance criterion is within ±1%R.C. When focusing on the negative pressure, it is also possible to perform calibration for the negative pressure and to provide only measurement data (within ±1%R.C.) according to the request from the customer.
    Regarding calibration, specify 020, 030 (focus on positive pressure) or 021, 031 (focus on negative pressure) in ⑤ above when placing an order.
