(c) Do the check of the input resistance (IR) of the pressure transducer
-------------------------------------------------------------------------------ACTION RESULT -------------------------------------------------------------------------------
On the Line Tester:
- set the switch C1 to INPUT R
- push on the pushbutton PB1 On the display of the Line Tester:
- make sure that the input resistance indication is between 1 KOhm and 10 KOhms.
(d) Do the check of the output resistance (OR) of the pressure transducer
-------------------------------------------------------------------------------ACTION RESULT -------------------------------------------------------------------------------
On the Line Tester:
- set the switch C1 to OUTPUT R
- push on the pushbutton PB1 On the display of the Line Tester:
- make sure that the output resistance indication is between 0.3 KOhms and 2 KOhms.
(e) Do the check of the insulation (IS) of the pressure transducer
-------------------------------------------------------------------------------ACTION RESULT -------------------------------------------------------------------------------
On the Line Tester:
- set the switch C1 to INSULATION
- push on the pushbutton PB1 On the display of the Line Tester:
- make sure that the insulation indication is 1.
(f) Disconnect the electrical connector (1) from the plug P1 of the Line Tester.
(4) Test of a rotating mechanism
(Ref. Fig. 301, 302)
NOTE : Two persons are necessary to do these tests:
____
- one person in the cockpit,
- the other person on ground near the applicable wheel

May 01/05 CES NOTE : If the result of one of these tests is not satisfactory,
____
replace the related rotating mechanism:
- (Ref. AMM TASK 32-49-17-000-001) and (Ref. AMM TASK 32-49-17-400-001) for the NLG wheel
- (Ref. AMM TASK 32-49-18-000-001) and (Ref. AMM TASK 32-49-18-400-001) for the MLG wheel
(a) Connect the electrical connector J1 of the Line Tester to the electrical connector (2) of the rotating mechanism
(b) Energize the aircraft electrical circuits (Ref. AMM TASK 24-41-00-861-002).
(c) Do the EIS start procedure (Upper ECAM DU and lower ECAM DU only) (Ref. AMM TASK 31-60-00-860-001).
(d) On the ECAM control panel, push the WHEEL key. On the lower ECAM DU, the WHEEL page comes into view.
(e) Do the check of the pressure-sensor simulation (PS 100)
-------------------------------------------------------------------------------ACTION RESULT -------------------------------------------------------------------------------
On the Line Tester: On the lower ECAM DU, on the WHEEL
- set the switch C1 to 100 PSI page:
- make sure that the tire pressure indication is 100 PSI plus or minus 5 PSI for the applicable wheel.
(f) Do the check of the pressure-sensor simulation (PS 200)
-------------------------------------------------------------------------------ACTION RESULT -------------------------------------------------------------------------------
On the Line Tester: On the lower ECAM DU, on the WHEEL
- set the switch C1 to 200 PSI page:
- make sure that the tire pressure indication is 200 PSI plus or minus 5 PSI for the applicable wheel.
(g) Do the check of the pressure-sensor short circuit +
-------------------------------------------------------------------------------ACTION RESULT -------------------------------------------------------------------------------
On the Line Tester: On the lower ECAM DU, on the WHEEL
- set the switch C1 to SHORT + page:
- make sure that the tire pressure indication is XXX or blank for the applicable wheel.
(h) Do the check of the pressure-sensor short circuit -
-------------------------------------------------------------------------------ACTION RESULT -------------------------------------------------------------------------------
On the Line Tester: On the lower ECAM DU, on the WHEEL
