4. Connect a digital ammeter (with a
 range of less than 500 mA)
 between the terminal 1 and
 terminal 2 of the circuit breaker
 1703GK (3702GD) with alligator
 clips.

 NOTE : Make sure that the digital ammeter is correctly calibrated.
____
 5.
 Open the circuit breaker 1703GK
 (3702GD).

 6.
 Make sure that the ammeter shows
 0 mA.

 NOTE : Take into account the tolerance of the digital ammeter.
____
 NOTE : If the ammeter does not show 0 mA, replace the fire shut-off valve
____ 1046GK (3702GD) (Ref. TASK 29-11-52-000-001) and (Ref. TASK 29-11-52-400-001) or ((Ref. TASK 29-13-52-000-001)) and ((Ref. TASK 29-13-52-400-001)).
 NOTE : With a permanent operation of the electrical motor of the fire
____ shut-off valve, because of an incomplete opening of the valve, the current range can be from 25 mA (clutch worn) to 400 mA.
 7.
 Disconnect the ammeter.
