Problem:Many calibration systems or equipment have a limited pressure range, and when calibrating instruments that operate outside this range, the equipment may not be able to deliver accurate calibration.

Solution:

• Select Appropriate Calibration Equipment: Ensure that the pressure calibrator, pressure pump, or deadweight tester you are using covers the full range of the instrument being calibrated. If your system has limited range, consider investing in specialized calibration equipment that can reach higher or lower pressure levels.

• Use Multiple Calibration Points: If your calibration equipment can't cover the full range of pressures, use a combination of calibration devices that can span the desired range. Alternatively, you can perform calibrations at multiple pressure points within the operating range to obtain accurate readings.
