ELECTRONIC HARDWARE ALIGNMENT Instrument Shop Procedure The following instructions are intended for instrument personnel to adjust the transmitter if necessary This procedure should be performed in an instrument shop or safe area location Do not perform electronic adjustments in the field Devices referred to in the following descriptions are shown on component location drawings D5990188 and D5990189 Proper field wiring for hookup is shown on drawing D5990196 These instructions assume 24 VDC power is hooked up the calibration of input electronics are operational and field wiring is in place Calibration of pH Input Input for measurement circuit zero is 0 00 V at high impedance BNC connector normally found in the wiring chamber in the back of the model 653 or on preamp in field J Box Measured voltage at pH test point TP pin 7 of U100 should be 0 600 VDC No adjustment required as the unit is factory set with 2 000 V in and pH set point set to 2 29 V via constant set in eeprom not field adjustable NOTE There is no span adjustment because the chemical calibration always varies it to suit the electrode Calibration of Temperature Input The temperature input of the 653 is so reliable that no adjustable electronic parts are needed The stability and repeatability of the 1000 ohm RTD temperature circuit typically needs no adjustment Adjustments often lead to lower accuracy due to the difficulty of knowing the true
