The ABN™ Aneroid Sphygmomanometer has been carefully checked to assure reliability and accuracy (± 3 mmHg of its full scale) prior to shipment. Gauge accuracy can be checked by making sure that the needle rest within the printed square when the unit is fully deflated. If the needle points outside the zero square, the gauge will give inaccurate readings. Return the unit for recalibration by a qualified professional. It is recommended to examine the accuracy of measuring instrument every year and after maintenance/repair.
