5.1 Measuring of the rate (Deltatest)
Press key (2) of keyboard " < 15' Hz" ["1 Hz ".]
Move the watch in order to secure maximum
signal.
Regulate amplification (6) by observing the level
control provided by the instrument hand (7).
Optimal adjustment is secured when the hand is at
the beginning of the black zone [green zone]
Select by means of (3) the measuring time of 12
[10] seconds.
Select by means of (4) the measuring accuracy of
.99 [1/100.]
6.1 Measuring of the power cell tension (Alitest)
With power cell placed on table, connect black
probe to top of power cell (-) and red probe to its
case (+).
The tension value must be in the region of 1.35V;
if it is below 1.25V, the power cell must be
replaced.
6.2 Measuring of the current (Alitest)
This measuring is effected by using substitute
power cell feed (15) connected with "Output" by
means of the feeding clip (13).
Press buttons (2) [1.35 V] relating to feed tension
of the watch and (8) [µA] enabling the current to
be measured.
The value measured should not exceed 15 µA.
6.3 Checking of the functioning limit tensions
(Alitest)
This checking is effected by using substitute
power cell feed (15) connected with "Output" by
means of the feeding cable (13).
Press buttons (4) [Uadj] and (9) [Vadj].
Check proper functioning of movement within the
tension limits of 1.15 V and 1.40 V (tensions are
regulated by means of knob (5)).
Note
The motor is said to function normally when the
second wheel makes one complete revolution in
one minute. It is important to check the passage of
each of the 60 teeth.
6.4 Analysis of motor - measuring of the coil
resistance
Note:
If the movement is under tension, it is necessary to
isolate the electronic module before measuring the
resistance.
Unscrew the two motor connecting-screws.
Slide an insulating leaf under the terminals of the
module (A and B).
Measure R by applying the probes (16) to the
terminals A and B.
The resistance of the motor
should be between 2 and 2.2 K. If this is not the
case, the motor module must be changed.
6.5 Measuring of the rate on Deltatest using
feed from Alitest
Connect Alitest to "Input"
of Deltatest by means of the special cable.
Proceed in identical manner to 6.2 : Measuring of
the current.
Press button Atten. Deltatest (12) [Switch on back
of Alitest in position 1].
