Surface Mounting:
It can be installed bysurface mount and connected high(+) and low(-) pressures with accessories.
Flush Mounting:
(1) Cut a 95(W)×80(H)mmrectangularholeonthe wall.
(2) Assemble the panel with the transmitter as shownabove.Connect the tubes (be careful of the high(+)/low( -) ports) and the
electrical terminals, then coat some glue on the back of the stainless steel installation panel, insertthe transmitter body into
the holeandpastethe panel with the wall properly.

Zero reset & Calibration:
According to diffe re nt environm ent and sensor’s characteristics , fo r long te rm of using, the s ens o r’s accu ra cy
ma yb e drift. The transm i tter should be ze ro reset after in i ti al installed to meet the spe ci fied a ccu ra cy, and be
ze ro res et pe ri odi ca ll y in e ve ry 6 -12 months’ us ing. It is recommended to be “ze ro reset” after the ini tia l 7 days
continuous working.
Zero reset: keep the high（+）/l ow（-）p ressu re ports un con nected in s table ai r, or directly connect them , p ress the
button “ZERO” for 5s to perfo rm “zero reset”. It means “remove the zero d ri ft of the transmitter in o rd er to imp ro ve the
accuracy”. It is recommended that this operation could be done periodi ca ll y.
Initial ze ro reset: when in i ti al power on, i t should be ze ro rese t after fu ll y wa rm -up and s table, to m eet the
s pecified accuracy.
Long term ze ro drift & reset: It m ay ha ve long term ze ro drift after continuous working; cus tom e rs can reset i t periodi ca ll y.
Re-cal ibration & ze ro reset: when re-calib ra tion needed, ze ro reset should be done firs t. A qualified s tanda rd
m anometer is needed for re -calibration operation. Please follow the operation procedures below.
Attention:
It should be power OFF du ri ng ins ta ll ing and wiring. When using 24 VAC , i t is s trongly re comme nded to power the unit
with independent trans form e r. If sha ri ng a 24 VAC trans fo rme r with other equipments s u ch as contro ll e rs, transmitte rs
or actuators , please m ake s u re the terminals 24 V and GND are connected co rre ctly. Othe rw ise, i t m ay reduce s erious
damages.
Warranty:
●It has l imited warranty for eighteen (18) m onths after the production date.
●It does not extend to any unit that has been s ubjected to m isuse or accident.
●It is , in any event, s trictly lim i ted to the replacement or repair of the product i ts elf.
RSA-TDPA Differential Pressure Transmitter - Operation Instruction
Button definition:
“SET”: Set/Confirm/Save; “SEL”: Bit Select/Decrease; “ADJ”: Adjus t/Increase; “Zero ”:Ze ro Reset
Zero reset: keep the high（+）/low（-）pressu re ports unconnected in s table ai r, or di re ctly connect the two, press the
button “Ze ro ” 5s to rese t the actual “zero point”. It m eans “rem ove the zero d ri ft of the transmitter in order to im prove the
accuracy”. It is recommended that this ope ra tion could be doneperiodically.
Operation instruction:
1. "P810":Reset
SET→SEL/ADJ→P810→SET
User can restore the factory default set. Input “P810”, “Pret” will blink, press button SET, all factory default set will res tore.
2. "P075":Set the response time (Default set: 0.7s, available range: 0.5-30.0s)
SET→SEL/ADJ→P075→SET→SEL/ADJ→XXX→SET. (XXX means set time).
3. "P083": Check LEDdisplay function,it will display the 4 digits one byone.
SET→SEL/ADJ→P083→SET
4. "P081":Set EngineeringUnit(Defaultset: 1, forengineeringunitPa, availableranges:1-5)
SET→SEL/ADJ→P081→SET→SEL/ADJ→XXX→SET (XXXmeans the code of engineering unit),then the relevant LED on.
(Index: 1: Pa; 2: kPa; 3: mbar;4:mmW.C.; 5: inW.C.)
5. "P485": Set RS485 address(Default set: 1, available ranges 1~255, but recommend 1~30)
SET→SEL/ADJ→P485→SET→SEL/ADJ→XXX→SET (XXX means RS485 address) Note
：Refer to the communication data table
6. "P484": Set RS485 RTUMode(Default set: 1, available 1 or 2)
SET→SEL/ADJ→P484→SET→SEL/ADJ→XXX→SET (XXXmeans RTU Mode index)
Index：1: 9600-N-8-1; 2:9600-N-8-2.
Calibration by user:
Even though the product can be re-calibrated by user, it should be operated very carefully. The calibration is already finished in
factory. It may be out of accuracy or even damaged after un-properly re-calibrated.
There are sets of parameters can be re-calibrated by user. Current outputs at both zero (4mA) and full range (20mA) or voltage
outputs at both zero(0V) and full range(10V). All calibrated data will be stored and kept in the flash memory even power supp ly is
fail. But the factory default sets are always kept and can be restored any time.
7. "P271": Re-calibrate analog output,include zero and full range
SET→SEL/ADJ→P271→SET→SEL/ADJ→”key”→SET→SEL/ADJ→Waitjump→SEL/ADJ→SET
“Key” is calibration password:1021.

Calibration method：Enter P271 and password, connect the transmitter with standard meter. At this time the LED will
alternatedisplay “ZErO” and “ FULL”. During “ FULL” display period(last about 25s), press SEL/ADJ to adjust the output become
10V or 20mA. During “ZErO” display period(last about 25s), pressSEL/ADJ to adjust the output become 0V or 4mA, then press
SET to finish. If adjust to the limit, it will display"Err".
