Recalibrating Gauge Transmitter Using Pressure on
the Transducer
Caution! Please observe that testing and recalibration of transmitters mounted in haz-
ardous areas shall be carried out by Ex qualified personnel.
When recalibrating the MAS2600 Gauge Transmitter a pressure calibrator with a range of -
1 to 3.5 bar should be used. It should have an accuracy of 0.05% FS or better, as well as a
4½ digit milliamp meter.
1. Set the calibrator to pressure mode.
2. Connect the pressure calibrator to the transducer via MAS2600 Test Cup, type
G022S100 (DPI610 and DPI603) or type G022S103 (DPI802P CAL KIT).
3. Check that the range select switch on the amplifier is correctly set.
4. In conditions of no pressure (atmospheric pressure) the output signal should be
adjusted to 4.00 mA on the zero potentiometer.
5. Increase the pressure to maximum and adjust the output signal to 20.00 mA on the
span potentiometer.
6. Remove the pressure and check the zero point
7. Check the linearity at 0-25-50-75 and 100% of the measuring range.
8. If necessary, repeat the steps 4 to 7.
