The Auto-Leader is a very handy carry around exposure meter. It allows the exposure to be measured very easily thanks to its pointer-tracking system which is based on the guide mark.

Preparing to operate Battery Use a 1.5V silver oxide battery (G13 AS designation). First, use a coin to remove the battery compartment cap (14) by rotating it to the left. Now load the silver oxide battery with the (+) side face up. Remove the battery if you do not intend to use the unit for a long period of time. Battery check The exposure meter needle will not point to the correct value if the voltage of the battery falls below the rating, and so it is a good idea to check the voltage before use.
Operation Film speed setting Set the film speed setting which you intend to use. How to set the film speed For the correct setting on the ASA scale (10), rotate the ASA set knob (12) and align the white mark on the black dial with the red scale unit in the ASA window. Reading out the exposure When the sensor (1 ) is pointed in the direction of the subject, the pointer (4) deflects in accordance with the brightness of the subject.
Movie scale (6) Measuring the exposure for movie cameras is performed in exactly the same way as that for ordinary still cameras except that the number of frames (8, 16, 32, etc.) is taken into consideration. Read out the value on the f/number scale (8) which best agrees with the number of frames of the movie camera and then transfer this setting to the camera. With a movie camera shutter open angle of 180°, the standard number of frames is 24, and this is indicated by the black line.
Interim scale units The interim units on the dial scales are as follows: Interim values of the ASA scale (10) [DIN scale (91)]
