Page 5: Section 1, General Information
SECTION 1 GENERAL INFORMATION Introduction PS-1020 Analog Transmitters are electronic devices utilizing solid-state integrated components. They provide the user with a selectable voltage or current output directly proportional to the input signal within a specified linearity. Description The transmitters are intended for field mounting close to the vessel site, thereby reducing installation costs. -

Page 9: Section 2, Calibration
SECTION 2 CALIBRATION Prior to calibrating the instrument perform the following calculations. This will enable you to determine where the dip-switches should be positioned for zero and span. Obtain the capacity and full scale output of the transducer/s from the calibration certificates. If required, convert them into the engineering units being used in the system. -
Page 10: Calibration Procedure
Calibration Procedure Remove the metal cover to expose the dip-switches, jumpers and trim pots as shown in Figure 2 below. Set the zero and span dip-switches so the calculated values are within the minimum and maximum mV ranges given in Tables 1 and 2. - Page 11 Calibration Procedure (cont’d) Apply a known weight and adjust the fine span trim pot for the correct output. Turning the trim pot clockwise increases the output while turning it counter clockwise decreases the output. Re-check “zero” and “span” calibration and re-adjust if required. Replace the metal cover after calibration has been completed.
