| Testing and Measuring Instruments | |
| The use of the following instruments is recommended in inspection and repair of the Yashica TL Electro-X: | |
| Voltage Stabilzer | |
| This instrument is indispensable to assuring high efficiency in repair and servicing. It is advisable to use a voltage stablizer featuring a voltmeter and ampre-meter that provides ready checking and reading of the output voltage and current. Moreover, teh use of a battery tool and lead wires featuring clips at one end is recommended. By installing the battery tool in the battery chamber in place of the mercury battery, electric power can be supplied readily from the voltage stabilizer. | |
| Insulating Resistance Meter | |
| This instrument which features an exclusive resistance scale permits reading of resistance over a range of several megohms to several hundred megohms and is employed in the same manner as an ordinary tester. Since it uses a high voltage power (approx. 500V), however, utmost precaution must be exercised to prevent adverse effect on other circuits. In the course of use of this insulating resistance meter, particular care must be taken to protect the transistors from the high-tension supply. | |
| Focal Plane Shutter tester | |
| This instrument permits varied types of tests and measurements of the function of the focal plane shutter, including the shutter speed (at the top, center and bottom of the picture area), speed of operation of the front and rear sectors of the shutter, and time-lag of the X flash synchronizer contact. | |
| Standard Light Source | |
| The standard light source is used for checking the exposure readout circuit. It is advisable to incorporate this standard light source in the light value tester which is generally used for testing and repair. | |
