Page 3: Safety Instructions
Scanning Head TK326 1. Safety Instructions The scanning head TK326 is developed only for scanning of rotor marks and LED’s of electronic meters. It is not allowed to modify the TK326 in any way. Only electrically skilled person (older than 18 years) having relevant education and experience which enable him/her to perceive risks and to avoid hazard/damage which electricity can create, are allowed to operate the equipment. -

Page 5: General Description
The scanning head TK326 is developed to scan rotor marks and LED’s of electronic meters. If the TK326 is used to scan rotor marks, pulsed LED’s light up the rotor disk. So the reflected light is pulsed as well and can be detected independent of the background light. The scanning heads TK326 can detect every single switching edge of a pulse and allows the automatic starting- and no load-test on ZERA test systems. -
Page 6: Scanning Of Led's
The switch on the rear side must be in the lower position („LED“ see chapter 2.3.2.). The potentiometer of the TK326 has no influence on scanning. The scanning head is positioned in front of the diode to be scanned in approx. 35 mm distance. The diode on the rear of the scanning head flashes in time with the pulse transmission. -
