TEMPERATURE TRANSMITTER:
GIVE 24VDC TO THE TRANSMITTER
CONNECT MULTIMETER IN SERIES WITH -VE TO THE TXT
GIVE RESISTANCE INPUT TO THE TRANSMITTER
GIVE LRV VALUE BY ADJUSTING THE DRB
ADJUST ZERO FOR LRV
GIVE URV VALUE BY ADJUSTING THE DRB
ADJUST SPAN FOR URV
GIVE 25%, 50%, 75%, 100% OF URV (RESISTANCE) AND CHECK THE
CORRESPONDING MILLIAMPS OUTPUT
PRESSURE TRANSMITTER:
GIVE 24VDC TO THE TRANSMITTER
CONNECT 250 OHMS IN SERIES WITH -VE TO THE TXT
CONNECT THE HART TO THE TERMINALS OF RESISTANCE
CONNECT THE TRANSMITTER TO THE SOURCE VIA REGULATOR AND MAKE
A T OFF CONNECT TO A MASTER GAUGE
VARY THE PRESSURE BY ADJUSTING THE REGULATOR
MAKE ZERO TRIM FOR ZERO PRESSURE THROUGH HART
ADJUST THE REGULATOR AND CHECK FOR THE LRV VALUE IF NOT
MATCHING ADJUST THE ZERO
DO THE SAME FOR THE URV
GIVE 25%, 50%, 75%, 100% OF URV (PRESSURE) AND CHECK THE
CORRESPONDING MILLIAMPS OUTPUT
DP TYPE TRANSMITTER
LP LINE SHOULD BE LEFT OPEN TO ATMOSPHERE
CONNECT THE HP LINE TO THE SOURCE AND DO THE SAME AS ABOVE
