11. To perform calibration of the LCD display you must first determine the Zero and Span This information is on a sticker located on the back of the display Adjustments are made via Zero and Span potentiometers see Figure 5 for location You may use either the RSV transmitter itself to perform calibration of the display or a 4 20 mA signal simulator Figure 5 LCD Display Calibration Adjustments DISPLAY RED ZERO DISPLAY BLACK SPAN CALIBRATION OF LCD USING 4 20 mA Simulator 1 Disconnect he LCD display from the transmitter by removing the RED and BLACK wires from their respective terminals 2 Attach the POSITIVE lead of the simulator to the RED lead of the LCD display and the NEGATIVE lead of the simulator to the BLACK lead of the LCD display 3 The simulator should be set to POWERED output mode so that loop power is supplied If your simulator is not capable of this function wire to 9 VDC batteries in series with the 4 20 mA simulator and the LCD display 4 Apply 4 00 mA to the LCD display 5 Adjust the ZERO potentiometer until the LCD matches the range indicated on the sticker in the spot labeled ZERO CALIBRATION PAGE 11 Apply 20 00 mA to the LCD display Adjust the SPAN potentiometer until the LCD matches the range indicated on the sticker in the spot labeled SPAN CALIBRATION The LCD display is now properly calibrated Re wire the transmitter at this time CALIBRATION OF LCD USING TRANSMITTER PROCESS
