Super Zoom Master L-608/L-608 Operating Manual Bedienungsanleitung Mode d’emploi Manuale d’istruzioni Manual de instrucciones DEUTSCH ENGLISH FRANÇAIS ITALIANO ESPANÕL ENGLISH Congratulations on your purchase of a Sekonic Super Zoom Master L-608/L-608CINE Exposure Meter. The Zoom Master L-608/L-608CINE is the latest addition to the extensive line of Sekonic Exposure Meters which have been market leaders. It was designed to be the ultimate meter, a do-all instrument for the most demanding pros. It is the first zoom spot meter on the market. Nine camera-quality lens elements are required to accomplish its 1°to 4° zoom range. Its sealed housing and controls make it water and moisture resistant. Yes, you can use it in the rain, but it is not an underwater meter. Its large LCD display makes readings easy and lights up automatically in dark surroundings. In order not to crowd the controls, four functions which are less frequently used, are confined to DIP switches, located in the battery compartment. Because of its many features, the L-608/L-608CINE requires this rather extensive manual. But since you will never use them all at the same time, once you have learned all about it, it is simple and its use will become second nature. The Zoom Master L-608/L-608CINE has undergone extensive quality controls at every step of manufacture. Please read this instruction manual thoroughly, to be able to take advantage of its many features and to obtain the long service life it is designed for. Thank you for your confidence in Sekonic.

PocketWizard OEM Radio Transmitter Module (T42) Mfg. by LPA Design for Sekonic Light Meters Theory of operation: The radio transmitter modules consist of a CPU chip, PLL, and VCO/AM Modulator. The CPU is a microcontroller with firmware that connects the radio module to the host CPU of the Sekonic Light meters. The two CPU’s (host & module) talk by way of logic level RS-232 commands. When the module CPU receives a command to change to a new channel, it loads the PLL with a new reference divider number from a channel look up table in it’s internal ROM. The module has the ability to switch between 32 different “channels”. See the frequency table for details. When the module gets a trigger command or a trigger pulse on the trigger input pin, it powers up the PLL and VCO parts on the board. It loads the PLL with the divider number, waits for a PLL lock detection, then keys on the RF amplifier and does a “fine” adjustment to the PLL. When the amplifier is turned on, the VCO in the PLL can shift off frequency by as much as 50KHz. By letting the PLL adjust for one milisecond before starting the actual command data pulses, the frequency error drops to less than 10KHz maximum at the start of the RF command. Once the PLL has been locked and the “fine tune” adjustment has completed, the modules CPU keys ON and OFF (OOK) the RF amplifier to AM modulate the carrier. The command packet is shifted out at 15uS bit rate for either 16 or 24 bits depending on the channel. Channels 17-32 are 24 bit, channels 1-16 are 16 bit. Each command transmission is sent three times with a blanking period of 3ms between each copy. The 1ms “fine tune” PLL adjustment is only done once at the very beginning of a “full burst”. The PLL, RF amplifier and CPU are then put into a low power shut down mode until the next trigger.

The device is normally manually operated and transmits a 3 packet burst control signal. Normal operation of the EUT complies with the parameters required in Part 15, Subpart C, Section 15.231. For testing purposes only the EUT was configured to continuously transmit. The Sekonic models L-608 and L-608CINE are electronically identical and utilize the exact same RF module. The only difference between these two models is the type of information which can be displayed on the LCD screen when the light meters are being used for cinematography measurements. Test Report No. R-3720N2 FCC ID: PFK-608-01 The L-608CINE model is capable of displaying more CINE speeds. TEST SAMPLE / TEST PROGRAM CThe transmitter is manually activated. CThe transmitter does not perform periodic transmissions at regularly predetermined intervals. CThe device can not be employed for RC purposes involving security. CThe fundamental field strength at 344.04MHz did not exceed 7250.01FV/M (Average) at a test distance of 3 meters. The fundamental field strength at 348.97MHz did not exceed 7457.08FV/M (Average) at a test distance of 3 meters. The fundamental field strength at 353.97MHz did not exceed 7665.54FV/M (Average) at a test distance of 3 meters. CThe field strength of harmonic and spurious emissions did not exceed 725.0FV/M or 500FV/M as applicable at 344.04MHz. The field strength of harmonic and spurious emissions did not exceed 745.71FV/M or 500FV/M as applicable at 348.97. The field strength of harmonic and spurious emissions did not exceed 766.54FV/M or 500FV/M as applicable at 353.97. CThe device can operate at 32 discrete frequencies over the range of 344 to 354MHz. The device was tested at the frequencies of 344.04MHz, 348.97MHz and 353.97MHz. The bandwidth of emissions did not exceed 0.25% of the operating frequency and was determined as follows: Fundamental Frequency=344.04MHz 0.25% of Center Frequency=0.86MHz 0.86 divided by 2=0.43MHz Bandwidth Range=Fundamental Frequency + and - 0.43MHz 344MHz - 0.43MHz=343.61MHz 344MHz + 0.43MHz=344.47MHz Bandwidth Range=343.61MHz - 344.47MHz Fundamental Frequency=348.971MHz 0.25% of Center Frequency=0.872MHz 0.872 divided by 2=0.436MHz Bandwidth Range=Fundamental Frequency + and - 0.436MHz 348.97MHz - 0.436MHz=348.534MHz Test Report No. R-3720N2 FCC ID: PFK-608-01 348.97MHz + 0.436MHz=349.406MHz Bandwidth Range=348.53MHz - 349.41MHz TEST SAMPLE / TEST PROGRAM (continued) Bandwidth Calculations continued: Fundamental Frequency=353.971MHz 0.25% of Center Frequency=0.884MHz 0.884 divided by 2=0.442MHz Bandwidth Range=Fundamental Frequency + and - 0.436MHz 353.97MHz - 0.442MHz=353.528MHz 353.97MHz + 0.442MHz=354.412MHz Bandwidth Range=353.53MHz - 354.41MHz CThe device uses an internal antenna. CRadiated Emissions from the EUT were measured in all three axis. Worst case emissions were found with the EUT in the vertical upright position. This orientation is also the position in which the device will normally be used. The attached Radiated Emissions test data is representative of this worst case orientation. DETERMINATION OF FIELD STRENGTH LIMITS The field strength limits shown below were calculated as instructed in Section 15.231. Fundamental Frequency: 344.04MHz Where F is the frequency in MHz, the formula for calculating the maximum permitted fundamental field strength for the band 260-470MHz, FV/m at 3 meters is as follows: 41.6667(F) - 7083.3333 =Field Strength Limit (FV/m) 41.6667 x 344.04=14335.01147 14335.01147 - 7083.3333=7251.678168 Field Strength Limit=7251.68 FV/m The maximum permitted unwanted emission level is 20dB below the maximum permitted fundamental level.
