14.2.3. Testing electric part
Measure total consumption current by means of the ammeter of the monitoring unit.
Check the shooting speeds using the control unit, remote control unit, and monitoring unit.
The test should be done with 60m and 120m film reels at least three times (start, middle, and end of the reel).
The camera should be loaded with one of the reels, and run. Measure consumption current. It should not exceed values listed in
the Table 12 (in normal climatic conditions).

14.2.4. Testing the image deviance
1)
load the camera with 60m reel of the unexposed negative film;
2)
put the camera onto tripod;
3)
shoot evenly lighted white field at all shooting speeds;
4)
process the film up to
=0.65;
5)
use a microscope to measure sizes ‘a’ and ‘b’ (Appendix 2, Figure 3) with not less than
0.005mm accuracy. Measure
a film at the part where speed was stable. Difference between average value of three maximum and three minimum
values of ‘a’ and ‘b’ will be the image deviance in horizontal and vertical direction. It should not exceed:
0.02mm at 24, 48, 96 fps
0.04mm at 144, 192, 216-240 fps.
14.2.5. Testing of the shooting speeds
Test the speeds on camera loaded with 120m film reel.
Measure the speed by means of the cymometer connected to the connector III9 of the monitoring unit at least three times – at
the start, middle, and end of the film reel. The cymometer indications should be within 5% of the values listed in the Table 12.
If the frequencies differ more, it is necessary to adjust them by means of the resistors R1, R3, R5, R7, R9, R11 (Figure 9) of the
control unit. These resistors correspond to the shooting frequencies of 24, 48, 96, 144, 192, 216-240fps.
14.3. Repair
The repair should be done by highly skilled tech only.
Repair of the claw mechanism, stabilizing and blocking mechanisms, and optical parts can be done at the factory or specialized
workshops only.
Reassembly of the ball-bearings can be done by skilled tech observing following conditions:
1)
adjustment washers can’t be replaced without precise preliminary measuring;
2)
replacing of the ball-bearing with similar ones is not allowed. The ball-bearings can be used in the camera only after
de-preserving and precise measuring of diameter of their inner and outer rings. Tightness of the outer ring should be
not less than 0.01-0.005mm. Gap of the inner ring should be not more than 0.005-0.008mm. Pressing force should be
applied to the outer ring only;
3)
screws can be replaced with same type, dimensions, and galvanic covering screws;
4)
replace of the cog wheels is allowed if new cog wheel has a preciseness degree not less that replaced one;
5)
change of the materials and coverings of the replacement parts isn’t allowed, since this may cause break of the
electrical contacts.
14.3.1. Using ZIP
The ZIP set is purposed for replacing broken parts. Replace of the electrical parts should be done by skilled circuit installer. To
replace a LEDs units:
1)
unscrew the LEDs unit from the plate;
2)
seal off the wires from the LEDs;
3)
replace the LEDs.
To replace the helical of the shutter:
1)
remove the camera front lid;
2)
remove the shutter unscrewing the central screw;
3)
unscrew the screw fastening the shutter unit to the body;
