7. attery operation optional YOKOGAWA FUNCTIONS Calibration involves inputting the same pressure level to both a calibrator and a transmitter and comparing the transmitter output with a value measured by the calibrator The MT220 comes with all the functions you need for such calibration work in the plant or field Practical functions include measuring transmitter output 1 5 V or 4 20 mA outputting 24 V DC for driving the transmitter and indicating the transmitter output error as a percent value The MT220 even has a pressure range pre adjusted to that of transmitters COMPATIBILTY The specifications of the MT220 are based on the earlier series of MT120 manometers to ensure compatibility both series also share the same communications commands HIGH ACCURACY The accuracy of pressure differential pressure transmitters has continued to improve from 0 25 to 0 1 and now to 0 075 That means the accuracy and stability of the manometers used to calibrate these transmitters must keep pace The MT220 employs Yokogawa s original silicon resonant sensor a high precision pressure sensing device We ve also set up an advanced calibration environment including a tightly controlled traceability system As a result our calibrators feature basic accuracy as high as 0 01 and excellent stability With the M1220 you can verify the performance of even the most accurate of pressure differential pressure transmitters i e 0 075
