Zeroing with Absolute Pressure Modules For zeroing, adjust the Calibrator to read a known pressure. This can be barometric pressure, if it is accurately known, for all but the 700PA3 module. An accurate pressure standard can also apply a pressure within range for any Absolute Pressure Module. Adjust the Calibrator reading as follows: 1. Press and hold Z . 2. Press a(Z) to increase or h (Y) to decrease the Calibrator reading to equal the applied pressure. 3. Release Z to exit the zeroing procedure. Press the U button to convert to any convenient measurement display unit. Pressure Calibrator Zeroing with Absolute Pressure Modules ZERO MMINAX BAmMRAOODMEETHROICLADDJ.
