4. Flash mode The following flash mode can be selected:

FSA02401-R.3244.A

(1) TTL flash mode (TTL) TTL auto flash control is possible. (2) Manual repeating flash mode (MR) Flash fires repeatedly at the fixed amount of light (1/8 or 1/16). (3) Manual flash mode (M) Flash fires at the fixed amount of light (1/1, 1/2, 1/4, 1/8 or 1/16). (4) Auto flash control mode (A) Flash is controlled at the aperture f/2, f/2.8, f/4, f/5.6, f/8 and f/11. (ISO 100) 4-1. TTL auto exposure control range Film speed: ISO 25 - 400 (FA, FE2, FG, F-401 or Nikonos V with sync cord for land use) ISO 25 - 1000 (F-301, F-501, F-801) Aperture f/1.4 - f/32 Distance 0.6 - 20m (Refer to the table in the page 4.) 4-2. Manual repeating flash Frequency: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 (Hz) Number of flashes: At Ml/8 setting: 1, 2, 3, 4, 10 (Displays -- at 10 setting) At Ml/16 setting: 1, 2, 3, 4, 5, 6, 7, 8, 20 (Displays -- at 20 setting) With the built-in batteries, repeating flash is available up to 4 times at Ml/8 setting or 8 times at Ml/16 setting (with fresh batteries). The number of flashes is increased by using an external power source (SD-6, SD-7).

IX. ADJUSTMENT PROCEDURE

FSA02401-R.3244.A

a) Outline There are six adjustment points; five variable resistors (VRt - VR5) and the focus assist illuminator angle. Because adjustment of the vaiable resistors VRl - VR5 is an electrical one, the order of adjustment procedure should be followed exactly. VRt: VR2: VR3: VR4: VR5: Safety circuit voltage (3503V) Recycling completion voltage (3302V) Flash output in M & MR mode Flash output in A mode Gammer in M, MR or A mode (regulated current)

Order of adjustment: VRl -- VR2 -VR5

FSA02401-R.3244.A

b) Adjustment Procedure Variable resistors VR1 - VRS can be adjusted after removing autofocus illuminator panel. However, the test point on the printed circuit B, which is used to measure the voltage, is not so close to the hole of the body mold E, and it is difficult to make contact. Therefore, it may be easier to adjust VR1, VR2 and VR5 after removing the body mold E to make the contact surely, because adjustment of VR1, VR2 and VR5 requires measurement of voltage. Be careful of the high voltage of the main condenser when disassembling. Use a DC regulated power supply (5.7V, 2A) if not specified.

GND can be taken on the circumference of the sync connector or the right pin of the external power source terminal.

FSA02401-R.3244.A

1) VR1

(Safety circuit voltage)

Adjustment of VR1 is to decide the voltage (350V) at which the safety circuit starts operation. As shown in Fig.1, by turning the variable resistor VR1 in a clockwise direction, the voltage decreases. Boost the monitor voltage by turning VR2 fully in a counterclockwise direction, then adjust. As shown in Fig.2, connect the SB-24 with a DC regulated power supply and apply approx. 5.2V as the power source voltage. (current limit: 1A) Connect a digital voltmeter between TP3 and GND shown in Fig.1. Adjust VR3 to start firing the SB-24 when the voltage at this point reaches 3503V.

Fig.2

Note: Be careful that the voltage in the main condenser does not exceed 355V in adjustment. The power automatically turns off unless the ready-light lights up for 60 seconds. In this case, turn off the power SW once, and then turn it on. 2) VR2 (Monitor voltage) VR2 can be adjusted to maintain the terminal voltage of the main condenser at 330V, and also to decide the voltage for ready-light lighting. Adjust VR2, so that the voltage of TP3 is 330V. (By turning VR2 clockwise, the voltage decreases.) If the main condenser voltage reaches the monitor voltage once, ascillatio~ stops. Oscillation does not start again in 32 seconds at longest. Accordingly, once the oscillation stops at the monitor voltage, it is necessary to fire the flash by pushing the openflash button. The adjustment of the voltage to light up the ready-light can also be completed by the above adjustment. Set the voltage of the DC regulated power supply at 3.8 - 4.0V and make sure that the readylight lights up at the voltage of 260 - 268V. Guide number inunediately after the ready-light lights up is: GN 3) VR5 (Gamrner) VR5 is adjusted, so that the level of light output in A, M or MR mode can be set correctly. Connect a voltmeter between TP4 and TP5. Then, adjust VR3, so that the voltmeter reads 18.4mV. (By turning VRS clockwise, the voltage decreases.)

4) VR3 (Flash outpu,t in M & MR mode)

FSA02401-R.3244.A

Place the SB-24 two meters away from a flashrneter, and fire it by pushing the open-flash button or by closing the X contact. With the flash mode selector set to M, the light amount 1/16 and the zoom setting 35rnm, adjust VR3, so that the value on the flashmeter should be as follows: (By turning the VR3 clockwise, the light amount increases) F4 - F4.25 GN8 - GN8.5 All the light amount in M mode (1/16 - 1/1) and in MR mode (1/16, 1/8) can be adjusted by the above adjustment at Ml/16 setting. Inspect the flash output at each setting (at least with zoom 28mm & 35mrn setting) in accordance with the specifications.

5) VR4 (Flash output in A mode) Place the SB-24 two meters away from a standard reflector paper, and fire it by pushing the open-flash button or by closing the X contact. Set the flash mode selector to A, ISO film speed to 100, zoom to 35mm and aperture to FS.6. Measure the flash output using a flashmeter and adjust VR4, so that the following value is shown. (By turning VR4 clockwise, the light amount increases.) F5. 6;t0. 1

6) Adjustment of angle of FL module unit The pattern of the autofocus assist illuminator should be inside the focus brackets of the camera. If the shoe cover is replaced, the position of the AF illuminator projection may possibly be shifted. Be careful not catch lead wires when screwing the shoe cover, because the FL module unit may be inclined if the wires are caught by the shoe cover. Note: 1. FL module is fixed on the body mold Eby two springs (//161) and three screws (#177). The position of the AF illuminator projection can be adjusted by fastening or unfastening these three screws. 2. If the FL module has a problem, replace the whole FL module unit with new one. Focusing of the FL module is already adjusted and only three screws (#177) should be adjusted.

FSA02401-R.3244.A

Adjustment should be made with the autofocus il,luminator panel detached. Attach the SB-24 to the F-501/N2020 on which an AF Nikkor 70-210mm F4 lens has been mounted. Set the focus mode selector to S (Single AF servo) mode and the lens to the 135nnn setting, and mount the SB-24 firmly on the camera accessory shoe. Place the camera (film plane) 1.6 meters away from the wall. Depress the shutter release button halfway to light up the AF illuminator light. As shown in the figure below, adjust three screws, so that the dark stripe of the AF illuminator light is a
